Hi!
After reading about freeNAS and ZFS on the docs and forum, I still have several noob questions.
I want to make a backup server mirrored with the ability to survive 2 simultaneous HDs failures. (Bad sectos, complete dead HDs, etc.)
If I understand, I will need 3 HDs (RAIDZ-2) for this. Correct?
Now, suppose I need to add more space, can I attach another 3 HDs and grow up the volumes online?
Sending snapshots at regular intervals to a remote machine (the idea is have a "clone" of the backup machine), in case of a complete disaster (maybe a meteorite strike my house) and loosing the complete machine, will I be able to retrieve the exact state at last snapshot? (I mean, just with the snapshot data) Or even move the "clone" backup machine to the original one and keep working as usual?
Thanks in advance, and sorry for my english, isn't my native language.
PS: In return, If my evil plans work ok, I will post all steps as "a noob guide for complete paranoid backup solution". :)
