Re: Incremental backups
I could do incremental backups for, say, every day of the week, and at the
end of the week compact my DB and do a full backup. This way I could roll
back do any day during the last week.
If I could precisely roll back a DB (something like what Dirkjan said:
roll-back-n-seqs, or roll-back-t-seconds), I could skip the incremental
backup and simply replicate. That way I would only need to do a backup
before compaction.
