I was thinking about building a FreeNAS running ZFS. Right now I shoot and iscsi target using openfiller VM to the wifes vista comp and it is in turn backed up through carbonite. Right now my collection of family vids and pics stands at 330Gb. I opened up an old pic to discover a black screen. I checked carbonite and found out it did a great job backing up the corrupted file. I think ZFS can help. What do you guys think? How cheaply can I fix this issue? If I build a box should I shoot for 4Tb? I need to be able to upgrade it if I have to, 1080 home vids are not small. Any help will be most welcome.
