Our backups have been very spotty ever since we migrated from Netware to OES. I just found this kb article from Symantec.

When does SMS support get utilized during backup when using the RALUS (Remote Agent for Linux and Unix Servers) agent to back up to the Windows media server.

Basically, TSA is not being used for the file system. I don't know if that means that the tsa configuration is actually hindering backups or just not helping. I'm getting ready to call symantec support, but I have a feeling I won't get far. Does anyone have any insight into this? Thanks.
