Before I had been doing incremental backup between my primary freenas server and backup freenas server, the backup server went down late last year due to power supply failure, now the backup server is finally back up, I'd like to continue doing incremental backup using snapshots, however the oldest snapshot on my primary server is newer than latest snapshot on the backup, since only 3 months worth of daily snapshots have been kept on primary:
Earliest snapshot on primary as of today: tank@auto-20170110.0015-3m
Latest snapshot on backup: tank-bu@auto-20161115.0015-3m
I am not sure if I can still do the incremental backup like this, since primary lost snapshot tank@auto-201601115.0015-3m long time ago:
zfs send -Rvi tank@auto-201601115.0015-3m tank@auto-20170410.0015-3m | ssh root@10.10.57.8 zfs recv -Fdvn tank-bu
Or can I do this? Will I lose deltas between 2016/11/15 and 2017/01/10?
zfs send -Rvi tank@auto-20170110.0015-3m tank@auto-20170410.0015-3m | ssh root@10.10.57.8 zfs recv -Fdvn tank-bu
A further question here is, is there a better way to do a straight mirroring between the two zfs systems for backup purpose?
Your help is much appreciated.
