Re: Audit log retention & disk space

Our auditors want 18 months of the audit journal available. Application
journals I keep for 14 days only.

If I only keep 3 months online and I need to restore from 9 months ago, or
more, I'll need to restore all the receivers from current to the oldest
point in order to preserve the receiver chain. If there's not enough disk
then the restore can't be done.

Even with the 18 months, we have plenty of available disk. We're using
less than 50% of the 21 TB in our system asp.

I would question the motivation for such big number. If you backup your
receiver on a regular basis, you don't need them online. You can restore
them on an as needed basis.

You could even, in case your management is nervous, setup a monthly
journal receiver only backup.

For example:
Keep 3 month on line. Each month, move the oldest month to a dedicated
tape. This way, you have 12 monthly tapes dedicated to journal. Easy to
locate, fairly fast to access. You can even duplicate them for extra
security.

Objet : Audit log retention & disk space

It's been recommended that we retain our audit log journal receivers on
DASD to 3-12 months. I figured the amount of disk required for that, and
it's not good. I know that DB journals have ways to reduce their size. Is
there anything similar for the audit journals? Other than changing what's
logged, any way to reduce their size?

TIA
