Is there any particular reason that I should consider moving to replication instead of continuing with rsync?
My setup: I've got two FreeNAS 8 boxes, HP Microserver N36L's connected by GigE and all UPSed.
Box1, primary NAS:
FreeNAS 8.2
5Gb RAM
4x2Tb RAIDZ1 (6Tb)
Box2, just contains a backup of Box1, no data of it's own. Also used for version upgrade testing:
FreeNAS 8.3b3
1Gb RAM
4x1Tb striped (4Tb)
So first question - will a 6Tb dataset replicate to a 4Tb destination? If not, that's the decision made for me.
(Box2's disks are the previous primary NAS RAID set, passed down into use in the backup device, which is why the difference)
I'm currently backing up Box1 by an rsync pull from Box2, which works fine.
I've also set weekly snapshots x 8, on both.
What benefits would I see from replication over what I have now?
Data transfer time is not an issue - it's a domestic situation without urgency.
Filecount isn't high enough to be a problem with rsync and memory, even though box2 only has 1gig.
Would I lose the ability to compress the data on Box2 and not Box1? That looks like a fs option so I would guess I get to keep the choice.
