It's been a while since I've asked this, and I had a few more questions.
Is this kind of backup common? I'll agree that this is not the most
efficient way to backup anything, especially considering that this is being
done to save all chagnes to all files which may have been modified throughout
the course of N hours. However, as some of you may understand, that's not
really my choice ;)
I looked at doing this at one point, but decided not to.
Having been working with LVM2 in the last few weeks, I'd say the that the
snapshot facility would be better suited to your needs than running 4
hourly backups. It's far less CPU intensive, but requires a small amount
of extra disk space and a small performance penalty (changed/deleted files
are copied out into the snapshot area, so you need enough freespace to
handle the changes).
