Hi!
I have a strange issue trying to backup / replicate a ZFS pool.
The pool has some filesystems and daily snapshots for each filesystem (created using sysutils/zfsnap). I am trying to replicate it on another pool like this:
The verbose output shows that first snapshot is being sent and at some point I get an error:
If I omit
I expect that deduplicating will spare a lot of space on my backup device.
Similar issue is described in some ZFSonLinux articles.
My system is the last update of FreeBSD 10.3-Release, AMD64
Did someone noticed such problem with sending/receiving deduplicated replication ZFS streams?

Code:
# zpool import -R /altback backz
# zfs create backz/srv1z
# zfs send -DRv srv1z@2016-09-30_00.00.00--1m | zfs receive -Fdvu backz/srv1z
Code:
receiving incremental stream of srv1z@2016-09-02_00.00.00--1m into backz/srv1z@2016-09-02_00.00.00--1m
cannot receive incremental stream: invalid backup stream
-D
(deduplicate) everything works fine.I expect that deduplicating will spare a lot of space on my backup device.
