We implemented Data Domain but the backup and restore times were terrible. The largest database is a 6.7TB DB that takes anywhere between 4 - 5 hrs for backup and 7-8 hrs to restore. Since this wasn't acceptable, we've implemented NetBackup in between with OST / Boost technology which puts the backup on to DataDomain. The backup times are now 2.5 hrs and restores are between 4-5 hrs max. - Imtiaz Date: Tue, 15 Feb 2011 13:20:26 -0500 Subject: Re: data domain backups From: ebrown2266@xxxxxxxxx To: oracle-l@xxxxxxxxxxxxx Data Domain backups work very well We've been using rman incrementally updated backups as described here: http://oraclestorageguy.typepad.com/oraclestorageguy/2010/05/data-domain-rman-incremental-backup-saves-space-and-time.html We are able to do a full backup of a 1.2TB database in less than 30 minutes.

They seem to be working fine, and our restore validation also worked fine. I am just curious if anyone has run into any problems/gotchas with data domain. -- Andrew W.
