I currently use an R200 via an NFS mount for backups with Sun's branded version of Legato. All systems are currently on Gigabit ethernet. Usually the entire backup completes in well under an hour (approx 2GB of data). I added a new filesystem into the mix yesterday which is still processing as of now. It's a 550GB dataset which Networker says it is writing at 2899 KB/s.
Have never had a problem with the setup and it beats a real tape library hands down.

Hi all,
Has any one else out there dropped a NearStore VTL700 (or other model) into an existing NetApp/Legato Networker environment? We're thinking about doing this, but we'd love to hear people's experiences with it.
Currently, we have SDLT 320 drives connceted via SCSI to the backup server, which talks over Gigabit to the Filers and other clients. In the new plan, we've have FibreChannel connecting the Filers, VTL and Backup server, with the tape library connected to the VTL only.
Some of our concerns how we're going to be able to restore legacy Networker backup tapes? Will the VTL handle tapes it doesn't know anything about and allow them to be imported?
We're also thinking of finally making the move to NDMP as well from NFS backups, but we're quite concerned about the limitations of DAR (Direct Access Restore) allowing us to restore large chunks of NDMP backups without having to manually break it into chunks due to Networker/NetApp limits?
