8 I tried sanoid, but it has a few problems which really become annoying when you have a lot of datasets:
9 1) every dataset is handled seperately, no use of recursive snapshots when datasets are inside the same tree
10 2) it keeps seperate hourly, daily,.... snapshots, which means it will happily create multiple snapshots with only a few seconds difference for every dataset around midnight.
11 3) when rolling back several snapshots, there are multiple errors reported because the cache (where does it store that?) does not match reality.
12
13 Have these been resolved yet?
14
15 I ended up writing my own system for this, got some extra intelligence in there to work around any possible error condition I have encountered.
