We have recently cut-over to using Veritas NetBackup with NDMP to perform a mixture of backups to filer-attached-tape and 3-way backups to other filers with tape. We are running DOT 5.3.4R3P2 on a mixture of 630's and 760's against NBU 3.2 with a recent patch set (one that includes the 3-way fix).

In both instance, we have found that sometimes a filer completes a dump (ndmp session goes away, backup snapshot is deleted, /etc/dumpdates is updates), but the backup job hangs in Veritas-land. This job hangs indefiately until manually killed, at which point it does not record the file history making the backup un-restore-able.

We're growing very frustrated with this issue. BudTool has been backing these filers up for 2 years with NDMP and relatively few problems. So far, NBU support has been disappointing to say the least.

Has anyone seen this? Is there a workaround or fix?

Also, does anyone know the mechanics of the "/etc/ndmpdlog.*" files? They are poorly documented in the DOT manuals. All of ours are zero length, but its unclear whether this is supposed to be the case (no news is good news). Does anyone know what they are supposed to look like?
