We use a device from Data Domain (the DD200 Restorer) which appears to NetBackup as a tape device and can be used with the Filers via NDMP. The appliance uses a lot of the same ideas as OnTap (apparently one of the first engineers at Data Domain was a former NetApp engineer) in how they perform data compression. As an example, even though the physical specs of the box are ~3TB storage, we're seeing data availability of up to 20-25TB (we can maintain about 6 weeks worth of full and incremental backups of our GroupWise and Filer on this appliance).

Data Domain also has a new upgrade which will do multi-site mirroring of DD200 data (much like SnapMirror)

If anyone is interested in more info on the box and what we're seeing out of it, let me know.

Hi Toasters,

This is a bit off topic. I'm looking for a disk backup solution to complement our current tape backup environment. Currently, we are using Veritas DataCenter v4.5, on Solaris, and Quantum P6000/7000 library using SDLT. A lot of incremental backup are already going to the R200 but full and NDMP still goes to tape. Interested in something like a virtual tape solution that presents virtual tapes to Veritas and backup to the disk backend, R200. Also, if the virtual tape supports NDMP for the Filer backup that will be great.

Appreciate any suggestions.

Cheers,
