lunadesign Posted October 2, 2008 Report Share Posted October 2, 2008 I have a "local" nightly disk backup set that 6 clients backup to. This backup set has the "Groom to remove backups older than" setting enabled and set to 30. On a weekly basis, I transfer snapshots from this backup set to one of two "offsite" rotating sets (with grooming disabled) that go offsite. Each backup set currently consists of two 500GB disks. I've been using all 3 of these backup sets for about 2 years now and they still work fine. My only problem is that over time the "local" set has filled up with lots of sessions for older clients that I no longer care about. There doesn't appear to be an easy way to clean these out other than manually "forgetting" each snapshot one-by-one (each one takes about 3-5 mins to process) and then running a lengthy grooming operation. Just navigating through the list of snapshots for the "local" set is pretty painful since there's no easy way to view by client or sort by columns in Retrospect. My original plan was to continue using the "local" set forever and retire the "offsite" sets every 3 years or so but I'm beginning to think it might be time to retire the "local" set as well and start a new clean "local" set. What do you guys think? Do backup sets get so cluttered over time that people generally retire or recycle them? Quote Link to comment Share on other sites More sharing options...
Mayoff Posted October 2, 2008 Report Share Posted October 2, 2008 I use my backup sets forever.... but I don't set grooming to 30. This is a really big number and will not free up very much space. Try setting it to 10 or 15. Quote Link to comment Share on other sites More sharing options...
lunadesign Posted October 2, 2008 Author Report Share Posted October 2, 2008 Thanks for the advice. I'm curious about your long-running backup sets - doesn't the processing time (ie, matching) take much longer if you have a ton of sessions?

Mayoff Posted October 2, 2008 Report Share Posted October 2, 2008 Yes, that is true. The more sessions...the longer the backup. My backup runs at night, so I don't notice it. Quote Link to comment Share on other sites More sharing options...
lunadesign Posted October 2, 2008 Author Report Share Posted October 2, 2008 One last question - are grooming operations supposed to take 3+ hours? It seems a little long. The backup set has roughly 800GB in it and the systems being backed up maybe have 500K files. Quote Link to comment Share on other sites More sharing options...
Mayoff Posted October 2, 2008 Report Share Posted October 2, 2008 Grooming is slow. 3 hours is not very long for grooming. Quote Link to comment Share on other sites More sharing options...
