Hi Bob,
I have had good experience with backup of clustered NT/Win2K servers.
Assuming that all the diskspace you would like to backup, on your array, is
allocated as clusterdisk resources in your cluster, then do a cluster
install as described in IBM Redbook SG24-5742-00 and "TSM Installing the
Clients" Appendix F.
There is one small snag - if the cluster fails over during backup
processing, backup will fail, but the next time backup starts, it will
backup from the node owning the cluster-disk resource. My advice - follow
the instructions carefully, or you might get undesirable results, such as
trouble with TSM Password registry key replication.

Subject: How to backup a shared disk array?


We have a storage array fronted by two, clustered NT servers.  The NT
servers are identically (or nearly identically) configured.  Each has a TSM
client installed.  We'd like to develop a TSM backup stategy that permits
daily incremental backup of both servers, including the storage array, but
without doubly backing up the storage array.  If either server fails, the
other server should be able to *automatically* assume the role of backing
up the storage array.  Either server should be able to restore storage
array files.  Any suggestions?
