Ok, a little bit of explanation on the title...
At home I have pool named "hulk" and a pool called "backuppool". The hulk-pool contains one RAIDZ-array consisting of 5 x Hitachi 3TB. The backuppool-pool consists of 2 x 2TB in a mirror. Those 2 x 2TB are placed in a Sharkoon QuickPort 3 bay. Easy for hot plugging/unplugging to take the disk to a remote location.
I would like to accomplish the following, by using zfs send and receive:
Every predefined point in time, take a snapshot of a set of filesystems on hulk and send these snapshots to backuppool. On backuppool I would to keep all the snapshots (unless I delete them manually of course ), doing so I would have a bunch of low-footprint backups for a long period of time.
I tried to do this ad-hoc, not yet automated:
zfs list after creating source snapshot
Apparently it creates a filesystem then, called Bart, no problem because I didn't add the parameter to create a FS with the same name as the source. But subsequent sends are failing:
sending snapshot fails
What am I doing wrong? Which parameters should I add to "add" the new snapshot to the destination?

must specify -F to overwrite itWhat am I doing wrong? Which parameters should I add to "add" the new snapshot to the destination?
