Hello
I have re-purposed my old X7DBE+ server as a backup server inside a 1U chassis (supermicro 1U) which is equipped with a BPN-SAS-815TQ backplane and 4 hotswappable drive bays.
The server currently has the following hardware specs:
-Supermicro 1U chassis with 4x hotswppable drive bays
-48GB DDR2-667 ECC RAM
-2x Xeon L5420 2.5GHz (4 cores each)
-The backplane (BPN-SAS-815TQ) is directly attached with SATA cables to the motherboard SATA ports. For now I assume this backplane supports only 2TB drives but if someone can confirm I'd appreciate...Otherwise I will contact Supermicro to ask.
The general idea is to use this older server to perform a backup of my main storage server which runs Freenas 9.10-STABLE. I would perform the backup manually, i.e. start the backup server, dock the hard drives in the hotswappable bays, perform the backup, unmount the drives, shutdown the server and bring the drives off-site.
My current Freenas main storage server uses 8x 2TB drives in a RaidZ3 config (11TB usable). Pool is currently 75% full. Out of the 8TB or so being currently used, there are about 2.6TB I need to backup, the remainder I can retrieve back from other sources should it be necessary.
Some questions come to my mind:

Some questions come to my mind:
- Since the backplane supports only 2TB per drive, that would be a raw capacity of 4x2TB=8TB for this server, therefore I wont be able to replicate my entire pool to this server but instead I will backup only specific root folders. Thats why I was leaning towards rsync and a classic linux distro. Should I opt for freenas although I wont do integral pool replication?
- On the backup server, should I configure all 4 drives to be a single concatenated volume (pool in Freenas language, LVM in Linux) or simply 4 independent disks? Whatever I do I will need to be able to expand (either by adding more drives, as I currently have only 2 drives but will get more in the future) or bigger drives (replacing the 2TB's by 4TB's if the backplane allows...)
