Which OS would you use for a NAS? Do any nix support encryption of the Data?
Probably some form of Linux or BSD.
All of them, depending on how you've setup your drives.
FreeNAS - every feature you get from a specialised NAS device, plus block-level deduplication if you use a machine with enough (8GB) of RAM.Quote:

So, for instance, you might have several physical disks (/dev/sda, /dev/sdb, /dev/sdc) combined into a MD RAID array (/dev/md0) which you might then encrypt (/dev/cr0) and then mirror to another machine (/dev/drbd1) before you actually format and mount the final resultant block device (i.e. do mkefs of /dev/drbd1 and mount it somewhere like /mnt/data).Quote:

Your downside to encrypting is you either need to:
a) login and mount the volume by supplying a passphrase upon reboot.
b) provide a means for the server to mount the encrypted volume automatically (that wouldn't be effective if it got stolen, for example).
We went with a) on both a QNAP (custom Linux) and a standard server running Ubuntu 10.04 and encrypted LVM.
Also remember the files are only encrypted when the volume isn't mounted.
