back-up solutions?

[David Schlosser]

To the ACE community:

What sort of solutions (hardware, software) have you implemented in
order to restore files in the event that ACE has identified a file as
being changed/altered/deleted?

I intend on having ACE monitor our server that contains digital
assets. We are considering using NTBackup to back up the server to a
LTO Ultrium 5 tape drive, then if we need to restore a file that ACE
has identified as being changed/altered/deleted, we will restore it
from the backup. Would like to hear if anyone has similar or other
solutions.

Feel free to respond to me directly off list if preferred.

In Chronopolis, we perform a manual restore on any files that ACE
detects as corrupt. We maintain three copies of all data at three
different sites (UMD,SDSC,NCAR) and at UMD perform local, nightly
backups using IBM's TSM product.

In the event of corruption, we do the folling at UMD:
1. Re-run the audit to verify that the file is indeed corrupt and it's
not an intermittent failure.
2. Attempt to restore from local backup if the file is indeed corrupt
3. If local restore fails, we'll copy from one of the peer sites
4. Re-run ACE against the failed files and test to see if they are no
longer corrupt.
