Backups to a diskpool mgmt class appear to be going directly to tape.

Our daily incremental backups are defined to the default mgmt class with the Backup Settings pointing to a disk storagepool. Recently noticed that the backups appear to be writing directly to tape. (I presume this has always done this, I only noticed it recently).

In this example, if I search the actlog for the session id of the backup I can see requests for tape mounts.

05/18/12 00:59:03 ANR0406I Session 896322 started for node SERVER1 (WinNT)
(Tcp/Ip server1.domain.com(3253)). (SESSION: 896322)

05/18/12 03:51:07 ANR0511I Session 896322 opened output volume A00708.

If I check via the java GUI for a restore, the backed up files are in the 'DEFAULT' mgmt class (which is diskpool) so I can't account for the tape mounts.

I am more familiar with managing AIX clients and have never seen this kind of behaviour, so I suspect it may be peculiar to Wintel servers.
In this config I am running TSM v5.5 Server on AIX with the clients running at v5.4 on Windows 2002 sp2 or 2003.

I can't imagine that it is a windows issue. Please consider that destination for client backups is set in copy groups and not management classes. Management classes contains migration destination for HSM. Please recheck your claim. Additionally check maxsize parameter on diskpool.

Hi,

there can be one more problem - directories are bound to the management class with the longest retention (unless DIRMC is specified) - so your files may be stored correctly on the disk but the directories are written to the tape. Can you check that?
