Disaster Recovery for SAN or NAS

[LawnBoy]

Just wondering what popular consensus is. Lets say a flood wipes out my NAS box, how can I have the data it held offsite? Tape backups? Sync to a duplicate box in another building?

Looking for "foolproof" here...

Tape backups off-site would be the first step, but depending upon the size of the NAS, you may never do a full restore from tape - it might just take too long.

Off site replication is the way we deal with DR for NAS. We have 2 NAS (Celerra) systems (1 in each site) that have storage on a EMC Symmetrix which is replicated from one site to another Symmetrix in another site.

Yeah, the problem with tape is time. It's taking 10 hours for my backups to run now, and we need to double our storage capacity.

How much bandwidth do you have between sites? My server farm is on 1Gb but the remote site I've spotted is only connected with 100Mb.
