If you use aggr snapshots with a few day retention you're 'paying for' the blocks locked in snapshots anyway. Better to have this retention (few days) at the vol level as standard and ease recovery when the unexpected happens. Maybe even require some special approval for customers requesting configs without snapshots.<br /><br />My 2 cents.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-766899806551963401.post-77973557531098555232010-12-09T05:15:03.028+05:302010-12-09T05:15:03.028+05:30Yeah, I agree with your comment that not everyone ...Yeah, I agree with your comment that not everyone does have a free aggregate to do a aggr copy for recovery of lost data from a volume or recovery of whole volume which was deleted accidentally, but yes you can do snap restore of whole aggr if feasible and most appealing reason is recovery when your aggr is corrupted and you have to run wafliron on your aggregate.<br /><br />I always recommend having 2-3% space reserved for aggr snapshots.Anonymoushttps://www.blogger.com/profile/06767496085573306941noreply@blogger.comtag:blogger.com,1999:blog-766899806551963401.post-53644612584994960052010-12-09T01:23:15.048+05:302010-12-09T01:23:15.048+05:30We all know you can recover this way but not many ...We all know you can recover this way but not many shops have extra disk or empty aggrs lying about that they can restore to. NetApp seems to be moving us toward ever bigger aggrs which will make this less of an option going forward unless you have 16+ TBs of disk unused. I'm certainly not going to recommend that people keep aggr snapshots running hourly, keep aggr snap reserve at 5% and keep an empty aggr the size of your largest aggregate just for aggr recovery. Kinda crazy. I'm glad for you and your user that you had the extra space but for most clients, this won't fly.equals42https://www.blogger.com/profile/15448030672437248095noreply@blogger.com
