One of our clients always ends every backup job with the following message:

17.03.2004 10:23:26 - Warning bpbrm(pid=2820) from client mailgw01: WRN -
Removable Storage Management: unable to export database (WIN32 21: Unknown
error)

What does this "Removable Storage Management: unable to export database"
message mean? I can not find any documentation on this warning.
Restore seems to work well, and the job finishes with status 0. But still, a
message like that makes me a bit worried.

We are using Netbackup 5.0 on a Win 2000 Master/mediaserver.
This particular client is Win 2003 with Netbackup 5.0.
