My plan for data "safety" for my audio library is still evolving.  Right
now, I simply have two sets of USB drives (2x500GB, 1x250GB in each
set).  These drives are FAT32; it's likely to be readable on just about
anything which has a USB connector!  I currently use Allway Sync (one or
twice a week, depending on how much I've added or changed) to keep the
drive sets synchronized.  (I also, of course, have the original CDs,
plus an extra copy of my downloaded songs in a backup directory on the
250GB drives, but I wouldn't look forward to re-ripping all the CDs and
transcoding and/or tagging the downloads.)

I just ordered a new linux box, primarily for SqueezeCenter.  It comes
with 500GB SATA, to which I will add 1TB SATA.  Haven't decided on the
filesystem yet, probably EXT2 or EXT3 for those drives, which will
contain a 3rd complete copy, in addition to the 2 USB copies.  Not sure
exactly how I'll sync, but I'll probably try to write a script whose
funtion is to run "flac -test" on all flac files found on a given
drive, so I'll periodically be able to test both the SATA and the USB
drives for bit rot.  I've no plans for RAID as this is just personal
audio; there's no special requirement for constant data availability.


My feeling at this point is that the best way to assure data integrity
is with the appropriate level on human involvement.  To much
automation, and the computer may quietly destroy data behind your back
when you're not paying attention.  To little automation and the process
of ensuring data integrity on upwards of 1TB of material becomes
completely unmanagable.  So, IMHO, the trick is determining what level
of human involvement gives one the best chances of keeping the data
intact over the long haul.
