alternating backup

[snoopy67]

I have devised a very simple scheme where i make a backup on partition 1 on my external disk, the next day a make the backup on partition 2 on the external disk, the next on partition 1 again, then partition 2, etc.
[sort of a "very poor man's incremental backup" ;-) ]

What i would like SD to do for me is just to remember the last time a made a backup on each partition.

Any ideas?

Cheers,
Gab.

Remember how, Gab?

Sorry, no ....

I'm really not sure what you mean.

@snoopy67: to semi-automatically backup to alternating volumes, you could e.g.

1. save the SD! settings for each backup volume separately,
2. create a script to start a SD! backup with (and to keep track of) alternating settings, and
3. use this script to start your regular backups to alternating volumes.

AppleScript is particularly handy for step 2 -- let me know if you'd like an example based on Dave's "Daily Backup" AppleScript application.

@Dave: hope you don't mind me intruding here ;-)

Thanks for the help. Unfortunately, i don't speak Applescript (just ksh & Co.), so i would like to ask you to provide the example

Thanks a lot in advance,
Gabriel.

How about simply using the scheduler built-in to SuperDuper? That is, schedule one backup for every MWFSun, and the other for TTSat. You would be using the same backup on Sun and Mon but otherwise alternating. Not perfect, but close and very simple to implement.http://www.shirt-pocket.com/forums/i...es/redface.gif

Ah -- I now see what was confusing here. I meant "How do you mean "remember"", and I think you took it as "Do you remember how"!

So -- hopefully darelon's response is helpful, but if not, could you explain a bit more about how you mean "remember"?

Thanks, and sorry for any confusion.
