i say keep it simple ... use find and tar
- find all changes since your last backup
- do daily, 7 day, 30 day, 90day incremental backups
per your paranoia levels
- full backups weekly, monthly, quarterly, semi-annually
per your paranoia levels
- tar it all up and copy it over to your backupd device
cd / ; find home etc -mtime -$DAYS | grep -iv $excludes | \
tar zcvf /mnt/zip/$today.tgz -T -
- let cron figure out daily, weekly, monthly, number of days
to span for incremental backups
- one script and 4 lines in cron that passes "days"
-- and there are tons of sanity checking you need to do ...
above couple lines becomes a couple pages of sanity checking
you should test that backyup actually works once in gazillion years
before you actually need to find a file from it
tons of free simple scripts
