1 Introduction 2 Installing Back It Up 3 Using Back It Up - Extended Version 4 Using the mini version 5 Examples Appendices A - Possible Errors and their removal B - File Structure on the PC/XT/AT Index
It you already own a Psion Organiser II, you will have begun to appreciate the value of information. For many people, the value of the data stored on their Organiser is far greater than the value of the machine itself.
If you own a valuable material item, a jewel or a painting perhaps, it would make sense to store it in a safe place. If your data is valuable, it similarly makes sense to create backup copies.
Back It Up is a program which allows you to save all the data on your Psion Organiser II onto either a hard or floppy disk of an IBM compatible PC, XT or AT.
If you should lose some or all of the data on your Organiser, Back it Up can restore all the data which was present at the last time you backed up your Organiser.
In order to use Back It Up you need
Back It Up can be used with all models of the Psion Organiser II.
In this manual, we have adopted a few conventions to make it easier for you to see what should be typed in on the Organiser and what should be typed in on the PC.
The names of keys on the Organiser are enclosed in square brackets and are in bold. e.g. [ON], the key which turns the Organiser on.
The names of keys on the PC are enclosed in angle brackets, e.g. <ENTER>, the key which accepts input on the PC. This key is also sometimes labelled <RETURN>.
Characters which you should type into either machine are shown in italics. Prompts which the program shows on the screen of either machine are shown in bold.
Some of the paragraphs in this manual will only apply when Back It Up is running on an Organiser with a 4 line screen. These paragraphs are marked *4.
On the Back It Up master disk are two versions, an extended and a small (mini) version.
The extended version can back up all the file types in common use on the Organiser, and has additional features to pick out the data you want to save more exactly. It uses about 16k of memory on the pack on which you store it. It you store it on pack B:, for example, 16k of pack B: will be used up. In addition, when you run Back It Up, it will need space in the main memory to run.
The mini version of Back It Up can also back up all tile types, but takes a more 'all or nothing' approach to the backup. Its advantage is that it can be stored in only 5K on one or the Organisers packs.
Furthermore, the mini version is split into two sections, MBACK (for backing up) and MREST to reload previously stores data. So you only need to have the most important software in memory, leaving more room for your own data and programs.
Back It Up always stamps a backup with the date on which it was used. The SAVEd files will always be saved in a sub-directory with the date in the name (see Appendix). This makes it easy to see when the backup was produced.
Of course, you will only get a correct date stamp if the correct system time and date are set on both the PC and the Organiser.
Back It Up always uses dates in the European format DD.MM.YY (two digits each for Day, Month, Year). If your PC is running the American date format, you should add a line to the file CONFIG.SYS (which should be in the boot directory of your PC) which tells the PC which country you are operating in.
For example add
COUNTRY=044 if you are based in the UK or
COUNTRY=033 for France.
For further information on this topic see your PC or MS DOS handbook.
The name used for each backup also contains a reference number between 0 and 9. You can choose this yourself, for example to differentiate multiple backups done on the same day, or to identify which person has made the backup.
Before you can start to use Back It Up, you must connect your Psion Organiser II to your PC with the Comms Link. One end of the Comms Link plugs into the top of the Organiser.
For some PCs, the 25 way female plug at the other end of the Comms Link cable will fit directly onto one of the Serial or RS232 ports on the back of the PC.
PCs which are compatible with the IBM PC AT usually need an additional item, called the IBM AT Link Up adaptor, to link the 25 way female plug on the end of the Comms Link to the 9 pin plug on the back of the PC.
IMPORTANT : Before you attach the interface to either machine, you must ensure that the computer concerned is powered down.
When you have connected both ends of the Comms Link, turn the Organiser on and load the communications software by pressing the [ON] key twice. The first press switches the machine ON and the second loads the software.
You can tell that the communications software has loaded by looking for a new option which should now appear on the Organisers top level menu (the menu which normally begins Find Save etc. The word COMMS should appear next to the OFF option. Should this not be the case then press [ON] once more.
If the COMMS option still does not appear, you have probably not inserted the Comms Link properly. In this case, switch the machine off, remove the cable then insert it once more and press [ON] twice.
Should the message OUT OF MEMORY appear, this means that there is not enough room in A: (RAM) for the Comms Link software. In this case you should free some memory, either by deleting unwanted items from A: or copying them onto either a Datapak or Rampak.
Return to the Main Menu and press [ON]. If you still have insufficient room, repeat the above.
It is recommended that you use a mains adaptor when transferring data to a Datapak. The jack plug on the mains adaptor fits into a socket on the Comms Link.
Before the Organiser and PC can communicate you must ensure that the communications parameters of both machines match.
Each time you use this connection you must check certain settings in the Comms Link parameters.
Choose the COMMS option from the Main Menu, then choose SETUP from the COMMS Menu (called SETUP hereafter). A list of communications parameters appears. The Comms Link manual has the full details of what these parameters are. To load Back It Up, the PROTOCOL must be set to PSION. For most PCs. the BAUD rate should be set to 9600, PARITY NONE, BITS 8, STOP 1 and HANDSHAKING RTS.

Load mini version of
4 line screen
Place your Back It Up master disk in one of your disk drives. e.g. drive A. Make this drive the current one by keying in the drive letter followed by a colon. In our example you would type A: followed by pressing <ENTER>.
Now enter the letters LZ it you are installing Back It Up for use with an LZ or LZ64 or the letters XP if you are going to use Back It Up with an XP or CM Organiser, followed by the drive letter which contains Back It Up followed by the letter of the drive where you wish to install Back It Up
For example, if the master disk is in drive A: and you wish to install Back It Up for a model LZ on drive C, type
A>LZ A: C: <ENTER>
The BACKITUP directory will now be copied to your target drive in the main directory. Finally the copyright message will appear. Now all Book It Up related files are copied to the new directory
The Comms Link program file (CL.EXE) must also be copied into the Back It Up directory.
The simplest way to make sure that this is done is to replace the Back It Up disk with the disk which came with your Psion Comms Link (in our example in drive A:) when the install routine asks you to put it there. The install routine will then copy CL.EXE from your Comms Link disk to the Back It Up directory. With that the installation on the PC is complete.
In order to install Back It Up on the Organiser you must load the procedure BACKINST from your PC to the Organiser through the Comms Link.
A>cd c:\backitup <ENTER>
C>cl <ENTER> on the PC.

4 line screen
Press the [MODE] key until the name of the pack which you want to store the Back It Up program on the Organiser appears on the Organiser screen. If you have enough memory left in A:, we suggest you use pack A:.
Enter the procedure name BACKINST on the Organiser and press [EXE]. The message FROM:BACKINST should then appear on the screen and you must press [EXE] once more. BACKINST should then be loaded from the PC to the Organiser.
When the transfer is complete, the message RECV A:BACKINST should appear on the screen again. Press the [ON] key until you return to the top level menu.
If the prompt FROM does not appear on the screen, the most likely explanation is that you have not set the PROTOCOL to PSION in the SETUP menu, described in section 2.2 above.
It the Organiser says FILE NOT FOUND then it is possible that you did not choose the PROCEDURE option from the FILE PROCEDURE menu.
If anything else goes wrong, check that you are properly connected to the first serial port of your PC and check the SETUP parameters again.
Enter the name BACKINST so that the screen reads
You will now see the source text of the procedure. Press the [MODE] key and select TRANS to translate the procedure.
If, for instance, you installed Back It Up to drive D: on your PC. then you will have to change C:\BACKITUP to D:\BACKITUP, then press [EXE].
Back It Up will then load a list of procedures onto your Organiser, which will take about 16k of memory. Once you have successfully installed all the other parts of Back It Up on the Organiser, BACKINST is no longer needed on the Organiser. If you are short of space, you can delete BACKINST from your Organiser (but do not delete it from the PC disk!).
The installation of the mini version follows the same routine as installing the extended version. The installation program in this case is named MINIINST.
To install the mini version of Back It Up on the Organiser, you must load the procedure MINIINST from the PC to the Organiser through the Comms Link cable. Follow the instructions in section 24, but wherever the previous section asks you to type in the name BACKINST, type in procedure name MINIINST. You need to receive procedure MINIINST, then go into the Prog menu and translate, save and run MINIINST, just as described for BACKINST.

Because the mini version of Back It Up is designed to save space, the loading program, MINIINST, does not automatically install all the parts of the mini version. MINIINST gives you the chance to load just the backup program or just the install program. Each at these takes about 5k of memory.
If you are going to use the mini version of Back It Up to make backups, when the menu Backup Restore Quit appears on the screen, choose Backup. when the backup program has successfully been loaded, you are returned to the same menu so that you can, if you have space, load the restore program as well.
Once you have successfully loaded the mini version of Back It Up, you can save space by deleting the MINIINST program used to do the loading.
Press [ON] until you are back at the top level menu of the Organiser (which normally begins Find Save.. ) then press [MODE]. The message INSERT ITEM or INSERT MENU ITEM will appear on the Organiser screen.
If you have installed the mini backup program, type in the name MBACK then press [EXE]. It you are using an LZ or LZ64, you will then have to tell the Organiser that MBACK is an OPL menu item.
If you have installed the mini restore program, type in the name MREST instead.
Press <B> to make a backup.
Press <R> to load a previously saved backup from the PC to the Organiser.
Press <ESC> to leave the program.
If you have pressed the wrong key, you can always break off by pressing the <Esc> key.
Each backup is identified by a name. The name always begins with the letter B. The next six digits are the digits of the date, in the form DDMMYY. So the name of a backup made on the first of January 1990 will start B010190. It you find that the wrong date is shown on the screen, you should check that the clock on your PC is set correctly.
The last digit of the name given to each backup is the reference number when you press <B> to start a backup, Back It Up will ask you lot your reference number. You can choose the backup number to be any digit between 0 and 9.
By using different reference numbers, you can make up to ten separate backups to be made onto the same PC disk each day. If, for example, three different people will be backing up their Organisers to the same PC, they could be given reference numbers 0, 1 and 2 respectively. If they enter their own reference number every time they use Back It Up, their backup data will be kept separately.
If two backups are made on the same day with the same reference number, the second backup made would overwrite the first backup. If two backups are made on the same day with different reference numbers, both backups are kept separately.
When you have entered the reference number, the CL program will run automatically. If you do not have the program CL.EXE installed on your PC in the same directory as Back It Up, the program will give you an error message and terminate.
Select BACK from the top level menu. You should then see the main menu in Back It Up - options Backup, Restore, and Drive.
is used to tell the Organiser on which drive Back It Up is installed on the PC.
The PC drive must be set correctly on the Organiser before you can go ahead and make a backup. If, for example, the Organiser screen shows Drive:a and Back It Up is saved on drive C: of the PC, when you run Backup, the program will report the error Path not found on the screen or the PC.
On the LZ and LZ64 models -
On the XP and CM models -
starts to create a backup. A default backup name appears on the screen. You should check that the name on the screen of the Organiser matches the name or the backup on the PC.
The first character is "B" followed by the current date, and the last character is the reference number. As long as the system date on your Organiser and the system date on the PC are both correctly set, you should not need to change the date part of the backup name, but if you are using a reference number other than zero, the last character of the name on the Organiser screen must be changed.
If you do not wish to create a backup, press [ON] until you arrive at the main menu. Otherwise pressing [EXE] brings up a further menu with different options.

(i) FULL - All packs with all files, diary files and alarms are saved.
(ii) OPTIONS - allows you to choose which files from which packs are to be saved. These option are different on the two and four line screens.
On the four line screen models LZ and LZ64 -
|*4||the Organiser screen shows a list of the different items you can
back up. If you press the [↑] and [↓] keys you will scroll through a
list which starts with packs A, B, and C and then goes on to list
Diary appointments, Alarms, ODB data files, DIARY files, OPL
procedures (either SOURCE or OBJECT code), Comms Link Setup
files, Spreadsheet files, Pager Setup files and, for the LZ
|*4||On the left hand side of each line is a + or - sign. For example, if
there is a + sign on the line for pack A, this means that files on
pack A will be backed up. If there is a + sign on the line for alarms,
all the alarms will be backed up. Lines with a - sign will not be
|*4||Pressing the [MODE] key changes the + sign to a -. By pressing
the [↑] and [↓] keys and the [MODE] key, you can choose which
items you are going to backup, and which you do not want to back
For example, plus signs on the lines for pack A and Spreadsheet
files, with minus signs on all other lines, will back up all the data
files on A and all the Spreadsheet files on A. Spreadsheet files on
B and C will not be backed up as these packs have been turned
|*4||Copy protected Datapaks cannot be backed up individually. They
are identified by a D in brackets by the name, Write protected
Datapaks are identified by an S in brackets.|
|*4||Pressing [ON] will bring you back to the main Back It Up menu.|
|*4||Pressing the [EXE] key ends the selection of the types, but gives
you the chance to specify a name mask.|
On the two line screen of models CM and XP -
|*2||the Organiser asks which packs and type of file you want to save
one by one.|
|*2||For example, it first asks if you want to save pack A. Answer by
pressing [Y] for Yes or [N] for No.|
|*2||Once you have answered whether you want to save pack A,
Options will then go on to ask if you want to back up pack B, pack
C, the Diary, Alarms etc. in each case you answer by pressing [Y]
Name mask - in addition to choosing the pack you want or the type of files you want, you can specify a name mask.
Initially, the name mask is set to *. The * symbol is used as a short hand notation for 'everything'. So it you want to back up all the files of the types and packs given a plus sign, just press [EXE] to accept the name mask *.
If, for example, you want to back up all the files beginning with a T, you can specify the name mask T*. Then, if you have a plus sign next to pack A and the spreadsheet files in the main list, all the spreadsheets and data (ODB) files with names beginning with T will be backed up.
The plus sign (+) is also used as a special character in the name mask. Whereas the star (*) is used in place at any group of characters, the plus sign is used in place of any single character. This allows a maximum file name length to be laid down.
Name mask: TEXT++++
will back up files called: TEXTPROG, TEXTDOK, TEXT but will ignore tiles called: TXTDOK, TIXT
Name mask: T* would back up all these files.
Name mask: ADR++
will back up: ADR11, ADR14, ADR%
but not: ADR1, ADR7634
Name mask: H+LL+
will back up: HALLO, HELLO, HULLA
but not: YELLOW, HALLO$
Standard setting: - after you have entered the name mask, you are asked whether you want to save the details of the mask you have just created and make it the standard setting.
If you answer yes, then a file will be created in the BACKITUP directory with the name BACKUP.DEF which will contain details or the setting you have created. Next time you want to make a backup to this setting, you can choose the STANDARD option.
If you have already created a standard setting for your backup after going through all the settings in OPTION, choosing STANDARD Will run a backup to the pattern you have set.
If you have not created a standard setting, nothing will happen.
When you have selected one of the three options and gone though its sub-options (if any) the backup begins. A message, "BACKUP RUNNING" appears. The next line shows the file currently being saved.
When the backup is complete, you are returned to the main menu. If more than one person is using these backups, it is recommended that you maintain a list of the date last used.
This is the option which we hope you will not have to use too often. To restore information to your Organiser from your PC, you run the BACKITUP program on the PC as normal, but press <R> for restore from the opening screen.
On the Organiser, select the BACKUP option from the top level menu of your Organiser. Back It Up will ask for the name of the backup which you want to restore. Unless you are going to restore a backup which was made earlier in the same day, you will probably have to change the date part of the backup name as well as the reference number.
When you press [EXE] you reach the FULL OPTIONS STANDARD menu.
As with the backup, FULL will restore all files, appointments, alarms etc. OPTIONS allows you to choose which packs and which file types to restore and STANDARD will restore the standard settings of packs and file types.
When the restore begins a message, LOAD BACKUP... appears on the screen of the Organiser. When the restore is complete, you are returned to the BACKUP RESTORE DRIVE menu.
Press <B> to make a backup. Press <R> to load a previously saved backup from the PC to the Organiser. Press <ESC> to leave the program.
If you have pressed the wrong key, you can always break off by pressing the <Esc> key.
Press <B> for Backup on the PC and enter the reference number of the backup you wish to create. Section 3.1 describes how to choose your reference number.
Run Mback on the Organiser. The message CREATE BACKUP appears on the screen of the Organiser. Below that the Organiser shows the letter of the PC drive on which it expects Back It Up to be running.
If the wrong drive letter is showing, press [MODE] until the right drive letter is on the screen. Press [EXE] when the right drive letter is shown on the screen.
If, for example. you try to run Mback with the drive letter set to A: and Back It Up is really running on drive C: or the PC, Mback will report error 188 and the screen of the PC will report "path not found".
Next you must enter the reference number of the backup you are going to make. Pressing [MODE] changes the reference number. The reference number you give on the Organiser must be the same as the reference number entered on the PC. With the mini version of Back It Up, you cannot change the date part of the backup name.
When you have pressed [MODE] enough times to make sure that the correct reference number is shown, press [EXE].
With the mini version of Back It Up, you can choose which packs to back up and whether to back up the current diary and alarms. If you choose to back up a pack, all the data files, diary files, spreadsheet files, Comms setup files, pager setup files and notepads on that pack are saved. If you want to specify more exactly which files you want to back up, you will have to use the extended version of Back It Up.
With the mini version, you can choose whether to backup pack A:, pack B:, pack C:, diary and the alarms. When you run Mback, all the backup options are initially set to off.
The cursor is shown as a single arrow pointing left on the four line screen and as a flashing rectangle on a two line screen. Initially the cursor is pointing to pack A.
If you press the [MODE] key, you tell Back It Up to backup the pack to which the cursor is pointing. On the four line screen, a double arrow head will appear to the left of a pack to show that it is currently set to on. On the two line screen, a single arrow head will appear below an item to show that it is set to on. Pressing [MODE] again will turn the same pack off.

If you press the arrow keys you will move the cursor to the other items. By moving around with the arrow keys and pressing [MODE] to turn packs on and off you set which packs (or diary or alarm) will be backed up. On the four line screen, you will need to press the [RIGHT] and [LEFT] arrow keys to move the cursor from the packs to the diary and alarms.
When you have finished selecting the items to be backed up, press [EXE] and the backup will begin.
To restore a mini backup, choose the <R> option from the opening screen of Back It Up on the PC and run program Mrest on the Organiser. You must specify the PC drive on which the backup you want to use is situated and edit the correct backup number which Mrest offers you until it is the number of the backup you want to use.
As with Mback you can decide which items to restore to the Organiser by pressing the [MODE] key to indicate that a pack or the diary or alarms should be backed up.
Remember that, if you restore the diary, for example, from a backup existing entries in your diary on the Organiser will be destroyed.
in the following examples, we assume that you are using a Datapak in slot B: and a Rampak in slot C:
On the PC, we assume that you have changed directory to the directory C:\BACKITUP and that you have run the Back It Up program by entering the word BACKITUP then pressing <ENTER>.
Then press the <B> key, then press [EXE] again to accept the serial number, which will normally end in zero.
Suppose you wish to make a backup of the current diary entries and data files in packs A: and C: with names beginning with "DATA".
First choose Backup from the main menu on the Organiser. Press [EXE] to go past the opening display.
From the menu which now appears, check that the Drive option displays Drive:C, showing that Back It Up is running on drive C: on the PC. If not, press [D] to choose Drive from the menu.
On the two line version, when you select Drive, you then need to press [MODE] until the letter C appears, then press [EXE] to show that you have made your choice.
On the four line version, each time you press [D] the drive letter advances by one letter. Keep pressing [D] until C appears.
Next choose the option Backup by pressing [B]. The message Create Backup appears and, if this was your first backup on 1st January 1990, the message Number: B0101900 would appear. For the purposes of these examples, we will leave the final digit as zero.
Press [EXE] to move to the next menu. The choices are now Full Options Standard.
On the two line version, the options are presented as a series of questions to which the answer is [Y] tor Yes or [N] for No.
On the four line version, the options are presented as one list, with a + or - sign to the left at each item. Items marked with a + are chosen to be backed up, items marked with a - are ignored. Pressing [MODE] changes between the signs.
In our example, you should input the following:
|NAME MASKS ?|
|Press [ON] to clear ++++++++ from two line or * from 4 line, then enter DATA++++.|
|[Y]||SAVE MASKS ?||[Y]|
OPL files means data files which can be created from the OPL language. not OPL programs, which are referred to as procedures.
If you choose the Standard option from the menu, you can create a backup or follow through a restore without having to set which items are to be backed up each time.
It you run Mback from the Organiser top level menu, the message CREATE BACKUP appears, with the question which drive on the PC, shown as PC-DRIVE: A if Back It Up is expecting the PC to use drive A.
If, as in our example, the PC is using drive C, press the [MODE] key until the screen shows PC-DRIVE C:, then press [EXE].
Now you will be asked for the serial number of the backup, which is entered with the help of the [MODE] key. The backup number given on the Organiser must of course be the same number that appears on the PC.
If you now press [EXE] you will see the question SAVE WHAT?.
If, for example, you wish to create a backup consisting of pack A, pack B, the Diary and the Alarms.
You enter, in our example, the following:
SAVE WHAT? ABCDW ^^ ^^
The letters stand for:
A: Pack A
B: Pack B
C: Pack C
When you choose Pack B, all the data files, program files, diary files etc on pack B will be saved.
The following section describes some common errors and their correction:
Your PC disk is full. Use a new disk, or erase some data from your disk, or install Back It Up in another partition of your hard disk where sufficient space is available.
Server Error means that the Comms Link program on the PC does not give a recognisable error on the Organiser. This can mean that you have not fitted a floppy disk correctly in its drive or that you have specified a drive which does not exist on your PC.
This error can occur when either using the Installation Program or when loading a standard mask (with BACKINST and MINIINST). With reference to the installation of software on the Organiser it means that one or more of the procedures which belong to BACK IT UP are missing. This usually means that you have told the PC to look in the wrong directory or on the wrong disk for the Back It Up files.
Ensure that all the necessary files are present and copy any that are missing from your master disk. You can also easily re-install parts or all of the program on the PC. During a restore, this error commonly occurs when you try to restore DIARY or ALARMS if you have failed to save these.
When loading a standard mask, this error occurs when either you have no standard mask or if you have erased the BACKUP.DEF file.
This error occurs when, during the installation of Back It Up another error occurred and you nevertheless ran Back it Up, or when you work with the Mini version and the Comms Link software is not installed.
This error happens only during Restore. Either there are too many files in the pack Index (on the pack being used) so that the limit of 110 files is reached. The solution is to remove any unimportant files either on the PC or the Organiser.
On the pack there is insufficient space to store all files. The solution is to remove some files, or on a Datapak use a freshly formatted pack.
Should any other errors occur, then consult the handbook for either your Organiser or Comms Link.
On the PC, BACKITUP.EXE creates the following hierarchy:
BACKITUP -----bddmmyyx------ Pack letter | | | - Pack letter | --bddmmyyz------ Pack letter | |- Pack letter | - Pack letter
This directory contains the complete Back It Up software plus the Comms Link program. Also the standard mask file BACKUP.DEF is stored here.
These refer to the individual Back-up files. With these you can recognise from the ddmmyyn the date the backup was created. The two positions dd show the day, mm the month and yy the year when the backup was created. The last figure is a serial number which can be freely used.
The file name is B1407894. This means that the backup was done on the 14.07.89 and the index number is 4. In this index the current DIARY and ALARM entries when the backup was created are saved. (DIARIES: DIARY.OB2, ALARMS: ALARM.BAK).
In these directories the backups of files from packs with the same name are saved. Should you wish, during restore, to load data to a pack from this section, then all data will be transferred when using the Mini version. or, when using the extended version, only the chosen files. If there are some files which you no longer wish to load then you must erase them. If you wish to load additional files onto the pack, then simply copy them as required.
The file suffixes have the following meanings
.ODB - OPL files, for instance MAIN
.OB2 - DIARY files
.OB3 - OPL Procedures, SOURCE or OBJECT Code
.OB4 - Comms Link Setup Files
