Hello,
I see a very big problem in this disk storage pools.
If you have an surge on your electricity network you
can potentially loos all your data including the backup !!

That is why the industry has developed UPS, RAID and auto-retracting
disk heads among other things.

Netapp is currently selling a SAN solution that utulizes ATA disk. They
are marketing this as either nearline storage or as an alternative to
tape. The array is a 12TB array with a cost approximating tape according
to their marketing collateral. Hope this helps.

We have also been looking at using a large diskpool.
It appears migration only uses one tape drive per node.
So, if you use TDP to back up 500GB to disk and then
run migration, it will only use one tape drive to
migrate that 500GB.
Is this true?
Migration has historically run as one process per

We've been thinking about a huge disk pool also. What we would probably do
is client backup to SCSI disk first then migrates to cheap disk or Tape.
What I really would like is to control which backups go to Tape or cheap
disk based on size. (We get great throughput restoring large files from
THat's not a bad idea Tim.
The other thing that I'd like WRT big diskpools or sequential storage pools is the
ability to migrate inactive files and leave active ones behind.
This would need a move data inact=y and another migration threshold for a storage
pool
migration would check for the
