First, I apologize in advance for the length of this post but I am confused about snapshots, replication and end of life (EOL) deletion and I need some help.
I have 2 volumes, each comprised of 6 4TB drives in a RAIDZ-2 configuration. The second volume is a replication target for the first.
I have 4 periodic snapshot tasks set on the "push" volume.
1. hourly snapshots with a 1 day lifetime
2. daily snapshots with a 1 week lifetime
3. weekly snapshots with a 1 month lifetime
4. 4 weekly snapshots with a 1 year lifetime
Each of the snapshots is recursive and their are 16 datasets on the push volume. The snapshots tasks and replication are working properly.
The problem I am having is that the hourly snapshots are not being deleted at the end of a day. (I expect the same problem exists for the other tasks but they haven't been running long enough for me to see). I understand from the handbook that the snapshots won't be deleted on the "pull" side when they reach EOL (that's a separate question for later) but I thought that snapshots would be deleted on the push side when they reached their EOL. Furthermore, only the most recent hourly snapshot provides the rollback option (why don't the others?).
I have consulted the handbook and google to no avail. I am hoping one of the experts here can point me in the right direction to solve my problem.
