expensive. Going the other route and putting, say, a DLT7000 on each filer is also nuts. Cost for one of those around here (toronto, ontario, canada) is something like $12500 plus the cost of a tape monkey to run around and change tapes daily.

We have all the above. It's not prohibitively expensive. The cost of the tape-monkey is amortised over the 100's of other systems he also tends.

Don't forget the media costs 300quid/night for a 6dayx13 wk cycle... about 4 times the tape drive cost itself.

BTW, my english parser keeps croaking over that CIFS statement.. Are you referring to the lost of CIFS-specific file information by doing, say, tar's over an NFS mount? If so, why? Doing a netapp-hosted dump pointing at a remote box with rmt and a tape drive perserves all CIFS specific information, afaik.

Yeees, point, CIFS isn't an obstacle.

Why 1000mb ethernet? I'm not sure what filer and tape hardware you have, but you think you need 128MByte/second throughput??!?

In my dreams. As I've said before though, in utter seriousness I *do* want to be able to back up 400GB in about 6 hours.

400GB is 6 hours is 19MB/s sustained. Only atm and Gb-ether can provide that over the network. Locally two F/W SCSI channels will provide it happily. So...

<lots of good case material snipped>

Seems like it's just a case of different strokes.
