Hello Everyone.
I'm currently speccing out a FreeNAS build for my family to keep both sensitive and non-sensitive data/documents resiliently stored, and I'm trying to minimize the size of the machine so it can be carried out of the house easily in the event of a hurricane by a not-so-strong person (Mini-ITX case, 6-8 2.5" 1TB SATA SSDs). In addition, I'm trying to plan for making regular backups which will go off-site to a secure location.
My questions are:
1) If I fill up all of the SATA ports for my 1 Z2 pool, can I use an external drive/enclosure off a USB connection to back up the entire pool, or should I plan to directly attach a single big drive for replication/backup on the motherboard?
2) If I can't use a USB drive and don't have any spare SATA ports, is backing up over the network to a drive on a PC generally the way forward?
3) Should I back up the entire pool to a single enterprise/datacentre HDD, or would it be better to back up/replicate to multiple drives? I'm not entirely clear on how backing up a Raid Z works when it comes to restoring. I.E., will the 2 copies of parity and checksums on the backup drive(s) "generally" mitigate drive read errors during a restore?
