I'm exploring backup policies such that if there's insiders quietly
altering them, we can skip the 'bad' changes:
Day 1: the initial good build
Day 2: legit/good updates were made
Day 3: an insidious/malicious update were made
Day 4: good legit updates/changes were made
We want to restore till Day 2, skip Day 3, restore Day 4.
Was told a GFS scheme as above will help but I tend to think
a mix of incremental plus differential backups is needed.
For DB, is it better to backup the OS files of the DB or take dumps & backup
the text dumps?
