asked on
with daily backups, what's the RPO we can commit to?
if we're taking backups daily ie every 24 hours (timings
of the backups (the backups can end between 1am to
4am, depending on how much is there to backup),
what's the RPO (Recovery Point Objective) we can
commit to? 24hrs or 30 hrs or it's 48hrs?
In the current risk management doc, it's indicated
as 48 hrs but since I joined not long ago, checking
if this is correct?

Also you have to take into account that restore may take even longer than taking backups.
(after detecting failure... so there will be loss of productivity DURING the restore.).
besides RPO,, also RTO needs to be known.

>RTO needs to be known
Yes, we do buffer in the restoration time to be about double the time
it took to restore from the last DR exercise.
I've seen in a previous bank that almost every week, there's a restoration
request to restore selected files/folder (not entire server) but they lack
the capacity/resource to do full restore quarterly (though in another bank,
they do it monthly) : can't we use the following reasons that our backups
have been tested:
a) we monitor backups for any errors
b) because it resides in data domain, we use sort of "explorer" tool to
read/open the backups periodically (quarterly) to verify?
c) in the days I work for a German bank, the OpenVMS command has
an option "backup/verify" which reads back the tapes each time
after a backup: isnt this a good alternative to doing full restore?

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Reading/verify is insufficient. A tape drive can do that but not actually restore.
You should be testing full restore of systems, as well as partial restores.

>Are restore practiced?
Only once a year during DR or when a recovery is raised.
We backup to Data Domain (not to tapes)
