Yep , i was ready to bet on it , but how do you want us to backup big netapps ?

i have around 2T of videos so it will take _a_lot_ of tapes , and time to backup this .

I can always setup a linux nfs server and use ndmp to backup it by a dedicated giga card , buts its a lot of complications .

I think backup is a real problem with current huge volumes and cheap ide drives are cheaper than tapes (or close to the tapes) .

The filer probably will not accept and it is certainly not supported to hook up any other RAID arrays to a filer. There is no device support for it.

Hello,

I'm wondering what is the best backup system for saving big netapps we have tried alot of solutions , but we finished by running 3 sets of netapp in snapmirror so A(master) replicates to B and C (slaves) all have now raid_dp enabled and spare around . So we have realtime B and C backups (we may cluster A and B) .

But as its quite expensive "backup" i'm looking for some classic backup with tapes for example but i know from the past that tapes can be big pain to manage (specialy as we have around 2.5T of data on A)

Anybody have some "tape backup" that realy works ?

sub question : anybody have tried to attach a cheap ide raid shelf to scsi port of the netapp and use it as backup ?

today its cheap to have 14x300 gig ide disk array with scsi port , so it could be better than tapes if its directly attached to the netapp , nan ?

Best regards cb
