I'm sending this here for speed, also it's not too big. I'll be sending
Shell 2.07M to .sources,binaries later this week and if I get a chance
to tidy up the code I'll send the source for SDBackup there too.
But for now heres the Doc file, and UUE file.
I wrote this backup program about a month ago when I got my Supra 20 meg
drive. It is CLI oriented, and is invoked in one command line. At the present
it does not support wild cards, but you can select a single directory
or single file. I have quite a few people who have backed up and restored
their entire drives using SDBackup with no problems.
It seems that the availability of PD backup programs is getting much better
MRBackup seems very good also, Mark obviously put alot of time into his
backup program and I don't mean to compete with anyone. I just have'nt seen
a PD backup program arround yet that uses the 1.2 archive bits. And it sure
is nice not to have to remember the last time you did a backup.
Some Features: (SDBackup Version 1.1).
--------------
- Is generic to any drives, eg. you can backup floppies to floppies.
You can even backup (compress) 3 1/2 to 5 1/4 disks.
- Uses LZ Compression.
- It does support 1.2 Archive bits and any file when backup up gets it's
archive bit set, thus you can do incrementals via date/time or by
using the archive bit. (-s LAST)
Shell 2.07M (sending out later this week) will show you the Archive
bits under a dir command, in the protection field.
- Has a built in maintenance mode for checking/marking/clearing archive
bits on files. Any big files or directories you don't wont backed up
you can then just set the archive bit on and use the -s LAST mode.
- Error recovery is easy since all the files are marked as you go,
restarting the backup half way through will continue at the file you
left off at.
- Having preformated your disks with labels XXXX_nn: (eg. Backup_1:)
you can stick a disk in df0: and df1: and walk away.
- Or you can have SDBackup format them for you on the fly.
- Can have SDBackup just show you the files that would be backed up
without doing anything by using the -V switch.
