SnapImage questions
This is a large site with Solaris NW Servers / Storage Nodes and a mix of Windows and Unix clients. A specific Windows 2003 server has 1.7 million fax files to be backed up and seems to be candidate for SnapImage.
The SnapImage docs are not clear whether this Win2K3 server running SI could back up the data to a Solaris NW server/storage node.
Can anyone confirm this ?
The docs also mention that SnapImage supports the new NetWorker Data Service Agent (DSA) feature.
A recent document issued by Carsten Reinfeld indicates that when using DSA with NDMP backups to a remote storage node, although the "client" is an NDMP host, the storage node sees the data as a normal NetWorker saveset, and does NOT need to have an NDMP device configured. This would also imply that the other NDMP-type limitations such as no multiplexing and no DDS would also fall away.
If this is the case, it would work very well in my environment. The Win2k3 host would run SnapImage and the NDMP client. The Solaris Storage Node would use the DSA feature and would not need the NDMP Tape server. The SnapImage savesets would be handled like any other savsets from other clients.
If this is not the case, we would have to set target sessions to 1 to disable multiplexing, and disable DDS.
Doing this on a heavily-used IBM 3592 tape drive on the Storage Node would be a show-stopper.
Can anyone comment on this ?
