- BACKUP & RESTORE
-
- These are two programs to help you transfer files across a
- Serial Link to a Series 3a.
- They are not complicated, but explaining exactly when you'll
- find them useful might be. And I'm no good at writing manuals.
- Still, here goes:
-
-
- BACKUP
-
- If you're the proud owner of a IBM PC or compatible, Macintosh
- or Archimedes, and a Psion Serial Link, you will be able to use the
- supplied software to treat your PC's (or whatever) drive(s) as Psion
- drives. Transferring files is then as simple as using the Series
- 3a's `copy' function. Easy.
- But what if, like me, you have another type of computer? In my
- case it's an Atari STE, but it could be an Amiga, or any other that
- has a serial (modem) port. You have to use the Series 3a `Comms'
- application to send files one at a time using one of the standard
- protocols: Xmodem, Ymodem or any variations thereof. You also need a
- program at the other end, to respond to the protocol. Tedious work,
- especially if you're doing a backup and need to transfer umpteen
- files. I have extra RAM in my Series 3a, and sending 3 megabytes
- file-by-file is no fun at all!
- So: here's a program to make the Psion end of the operation
- easier. BACKUP will scan through the drives you specify, listing all
- the files it finds, and create a `script' file. This can then be
- translated, and executed by the `Comms' application, to send all the
- files, one after another, automatically. If you have a file transfer
- program at the other end that will receive files one after another,
- you can go away for a well-earned cup of tea or coffee, while your
- computers chug away merrily!
-
-
- FEATURES
-
- You can specify which of your Series 3a drive(s) (M, A and/or B)
- are to be backed up.
-
- You can specify the name of the script file to be created (the
- default is \SCR\BACKUP.SCR).
-
- You can set the serial port parameters: baud rate, parity, byte
- length, flow control, and file transfer protocol.
-
- You can also write out a list file for use with the RESTORE
- program (see below).
-
- To make backups easier, BACKUP can list only those files which
- have altered since the last backup.
- It makes use of the MS-DOS `archive' file attribute. This is set
- whenever a file is created or written to, but otherwise ignored.
- There are two options in BACKUP to control this: `only changed'
- will list only those files with the archive bit set, and `reset
- changed' resets the archive bit on those files, so they won't be
- listed next time. (Take care when using the second option, as if you
- make a mistake, you can't re-run BACKUP to get the same list of
- files.)
-
- USING BACKUP
-
- The on-screen buttons are toggled by pressing their initial
- letter: they are activated when the `light' next to each turns
- black, and the button appears depressed. The other options are
- accessed by menu.
- Once you have set up the options you require, press ENTER or
- Psion-G to start scanning and creating the script, or ESCAPE or
- Psion-X to quit.
-
- To transfer the files, translate the script file in the `Script'
- application, and execute the result in the `Comms' application (both
- of which come with the serial link).
-
-
-
- RESTORE
-
- BACKUP is for backing up files from your Series 3a to another
- computer. What about restoring files? Transferring them in the other
- direction is not so easy. I haven't yet found an Atari program which
- will send many files in one go, and so I have to send them one by
- one, by hand. But what happens at the Psion end? If you're using the
- Ymodem protocol, the filename is sent along with the file, so the
- Series 3a knows what to call the files it's receiving. But it
- doesn't know where to put them. So ... (blare of trumpets) ...
- here's RESTORE. Using the file list created (optionally) by BACKUP,
- it recreates all the directories and subdirectories, and moves all
- the files to their rightful places.
- In the dialog box, specify the drive where all the files to be
- restored are (they should all be in the root or top-level
- directory), and the name of the list file created by BACKUP, and
- press ENTER to restore, or ESCAPE to quit.

- MORE INFORMATION
-
- BACKUP and RESTORE were written by me for my own use - I was so
- fed up with transferring files by hand. I hope they're of use to at
- least someone out there!
- If you have any comments, you'd like alterations made, or have
- any complaints, or even tokens of appreciation (well, I can hope,
- can't I?), please contact me:

-
- Although I'm happy with how these programs work, I'm afraid I
- can take no responsibility for any problems you may have. If your
- Psion forgets everything you've ever told it, or starts thinking
- it's a cabbage, please don't complain to me!
-
- This program is freeware: please distribute it freely to your
- friends, BBSs etc. The only restrictions are that this text file and
- the two programs are kept together, and that no alterations are
- made.
