What do people do for enterprise-wide Netapp backups? It's nice to plug in a big tape drive into the dedicated SCSI port on each filer, but management becomes a hassle, and the hardware itself gets pretty expensive. If you centralize everything to a backup server and do dumps over the network, what do you use to manage the scheduling and auditing of the tapes? Is there a way to get Amanda to work with a bunch of Netapps? Anyone using NDMP-based tools?
