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.
