Re: Differential Backups

Can you show me an example on doing a backup using xdelta?

Thanks

baseline dump, and just keep the diff, right? Then to do a restore I would
just patch for the point in time I wanted to restore to? Seems like it
would
work, but whether it would save any hard drive space would depend on how
much
activity the database saw. Anyone doing this now?

idea is god, but dont use suggested diff program. go for xdelta. it's
algorithm is much better - faster and definetly less memory-eating.

TIP 2: you can get off all lists at once with the unregister command
