We forgot to mention: Test the restore *before* you need to restore.  You
may find that the restore takes four times as long as the backups.

Rule of thumb 1 - restores always take at least twice as long as backups.
Rule of thumb 2 - backups never go wrong, restores always do.
Rule of thumb 3 - Rules of thumb are usually optimistic.

My rule of thumb.... Restore = backuptime x 2

I never past this time but it includes also the installation of a fresh OS

Hi

Does anyone have a rule of thumb for backup time ?  Could we say that if the
backup is more than 5 hours, it could make things more difficult for the
restore (downtime).

Example you restore during 7 hours to see that something went wrong. You
lost 7 hours.

I never had to do a disaster recovery yet, most of the time, does it take
the same time approx as the backup time to restore?
