as repository for our backup copy jobs I would like to use FreeNAS (4x4TB RAIDZ on HP Proliant ml310e v8) with iSCSI. A second machine will be installed later as shall be used as offline storage using FreeNAS replication. The FreeNAS machine is solely used as Veeam Target.
Current backup sources: 2 small Hyper-V machines (Veeam Essential), some small Linux machines, one big phys. Server inclusing file service (~2 TB of data), some smaller phys. server
Is there a best practice or "what to avoid" using iSCSI as repository target?
Are there any general drawbacks associated with this approach?
