Vaulting of NDMP backups

[tbiller]

I have four NetApp filers each with two LT0-2 tape drives attached over SAN for three-way backups.

(Robot control is handled by the Master server)

What's the best practice for Vaulting these backups? Do I need more tape drives to be made available to the media server that holds the storage unit for these backups?

Is Vaulting even possible in such a configuration?

Thanks in anticipation.

Are you going to setup vault just to eject the tapes, or do you want to make duplicate copies and eject those?

Hi Rusty,

Thanks for the reply.

Duplication and ejection, usual Vault stuff.

hello tbiller. i have a 960 with about seven terabytes, i vault the inc's, but for the fulls i run a second backup.
at one point vaulting full's started taking longer then it was for me to run a second full backup.
ndmp has been the disdain of my disaster recovery plans! we are finally getting rid of our filer, but what a bugger to transfer the data off. it's like hotel california, you can check in but you can never leave. it's no wonder that network appliance is doing so well.

note: don't forget to enable hardware compression on your drives [lto]!

To run duplication you need a drive for the read of a tape and a drive for the write. If you backups are large it would be easier for you to just vault the originals out.

Comtec - thanks for that.

Can the existing drives attached over fibre to the filer be used for this duplication? Is that supported or even possible as they are NDMP drives? Or should I define two more drives to the media server the storage unit is running on for these dupes?
