ZFS Replication or Veeam replication?

[snas]

Current situation:
2 servers with freenas installed, both have 8*2TB disks in a raid 10 mode

However
Freenas-1 is equipped with SAS disks and (raid1) ZIL ssd's and a L2ARC ssd
Freenas-2 only has sata disks and no SSD's

What we are currently doing: Both servers are setup as iscsitarget and both servers are known in the vmware environment. 3 times per day (8:00, 14:30 and 22:00) veeam runs replication tasks wich copies all VM's from datastores on Freenas-1 to Freenas-2. (and ofcourse once a day at 1:00 to an offsite location).

Would it be wise to replace veeam with ZFS replication? It for sure will be a big license cost saver.


The benefit of veeam replication right now is that we've got separate setups not linked into each other, veeam is the bridge in between and it has been a proven and visible technology to us.

We could stop using veeam and start using ZFS replication, I wonder if its just as reliable as veeam.

Has any body played with these thoughts before, and what was your outcome?

anyone? :)

ZFS replication is reliable, but you'll find a certain reluctance in discussing virtualized setups, due to the complexity of most setups.

If the setup is reasonable (doesn't make jgreco lose his faith in people reading what he writes), ZFS replication is probably the better alternative. The fewer layers of abstraction between FreeNAS and what's going on, the better.
