Just as another data point, apparently a year ago my backup server wasn't backing stuff up, so for the past few days my nightly backup hasn't had anything to do for the "remove incremental > 1 year old" step it does. You know what? Instead of the process finishing at 6-8pm it's finishing before 8am! In other words, it takes 7 hours to backup all my systems, and then 10-12 hours more to remove all the year-old incrementals. Yes, the removal of snapshots is taking longer than the backups themselves. Based on this, if I had unlimited disk space I would never remove an incremental. But disk space is not unlimited, and I figured 1 year was a good cutoff. I wish this were faster. My worst offender is one particular system: 3 hours to backup the server and 8 hours to remove an incremental from that dataset. That seems.... unbalanced. -derek -- Derek Atkins 617-623-3745 [email protected] www.ihtfp.com Computer and Internet Security Consultant
