Backup of local windows files through NDMP (NetApp) attached
Posted on 2011-05-09
I have a NetApp 2040 attached via fibre to a small tape library.
I used BackupExec with the ndmp option license to coordinate the backup of volumes which works really well exceeding 1GB/min.
In addition to this, I have been asked to incorporate the backup of some locally attached disks on our windows servers (i.e. not LUNs) which I am able to add to our backup plans. When I try to backup via this method, I get a maximum throughput of about 12MB/min which is way too slow. I understand this may be a bit slower because the way I understand it is that in a pure NDMP backup, all data stays within the NetApp <> Tape library fibre connection whereas the windows disks go via the BackupExec server through the LAN to the NetApps then onto the tapes.
Am I missing something here? Is this a configuration issue or have I misunderstood what is possible with this setup?
