Disks are much higher volume and are forced to be reliable "enough".
Hehe... as someone who had to explain to a customer that 2500+ drives
needed replacing due to a manufacturing defect don't tell me anything about
"reliable enough".. Those were FC drives by the way.
Ok I'm rambling, I'll stop, but tapes died
for a reason!
Well, for a lot of customers they are still very real. More for archiving
than for backups in some cases. I personally trust *good* tape technology
more than el-cheapo bit SATA drives (SATAn drives as one of my colleagues
likes to call them when they are causing grief). If you aren't backing up with a crc then you are
doing it wrong.
True, but CRC does not buy you much if the media are fubared enough to be
largely unreadable.
If you want archive, write it to dvd or bluray and
pull them out and
rewrite every 5 years.
At least. Have multiple copies of the same data. Use different media
vendors for those copies. Added bonus for using different media writer
drives. Store under controlled conditions, esp temp &
moisture. DVD & BR are basically consumer electronics stuff, so use ample
caution.
