Hi Bill, I totally agree with you on the DIRMC topic, and like you, I built a specific disk-based mgmt-class with is the recipient for WIN directories. The problem I'm facing is AIX specific (no dirmc was built here, as directories pathes are supposed to be stored within TSM db), and your assertion :
> I believe that TSM backs up the directory, too, if any files have changed in that directory. seems to be opposite to what Richard Sims (shall I call him "Master" ?) says ... Maybe we should wait for his answer, before dueling ;-) Cheers.

I believe that TSM backs up the directory, too, if any files have changed in that directory. And unless you specify a DIRMC, TSM uses the management class with the longest retention for DIRECTORY entries. This was a problem people saw before IBM implemented the DIRMC option. For Unix servers, directory entries are just entries in the TSM database and do not have any associated data. Unlike Novell and Windows where you have "data" like the ACL's associated with directories. Then you have space occupied in a storage pool. We always create a DIRECTORY management class with the highest retention and force the DIRMC option out with client option sets. The destination storage pool for this is a DISK storage pool that doesn't migrate. Just gets backed up to copypool tape. That way restores are quick as the data comes right from disk.

Hi *SM'ers, I recently found that one (surely others too) of our AIX clients was getting part of it's directory structure backed up everyday although it did not change, but can't find the reason why. As Andy says it in his excellent web page : A normal Incremental Backup will *not* back up directories whose timestamp has changed since the last backup. We're performing incremental backups, copymode used for this client is set to modified, so I can't understand what's happening ! The worse is that the mgmt-class having the longest retention period (retonly 768) in this domain is used for storing that data, so I end up with thousands (probably more if other servers are affected !) entries in TSM DB which are worthless. This in an example of what I get, using "show version" (snippet of it) on this server: /export/mksysb : / (MC: BACKUP_2_YEARS) Inactive, Inserted 01/07/05 20:51:51, Deactivated 01/10/05 20:37:15 ObjId: 0.539953678, GroupMap 00000000, objType 0x01 /export/mksysb : / (MC: BACKUP_2_YEARS) Inactive, Inserted 01/10/05 20:37:15, Deactivated 01/12/05 20:37:32 ObjId: 0.541340571, GroupMap 00000000, objType 0x01 /export/mksysb : / (MC: BACKUP_2_YEARS) Inactive, Inserted 01/12/05 20:37:32, Deactivated 01/14/05 20:37:16 ObjId: 0.542636928, GroupMap 00000000, objType 0x01 /export/mksysb : / (MC: BACKUP_2_YEARS) Inactive, Inserted 01/14/05 20:37:16, Deactivated 01/15/05 20:38:31 ObjId: 0.544018035, GroupMap 00000000, objType 0x01 /export/mksysb : / (MC: BACKUP_2_YEARS) Inactive, Inserted 01/15/05 20:38:31, Deactivated 01/16/05 20:38:29 ObjId: 0.544640259, GroupMap 00000000, objType 0x01 /export/mksysb : / (MC: BACKUP_2_YEARS) Inactive, Inserted 01/16/05 20:38:29, Deactivated 01/17/05 20:38:53 ObjId: 0.545097616, GroupMap 00000000, objType 0x01 This is a NIM server, where "MKSYSB" files from other servers are stored everyday, so the content of the directory is changing, but not it's structure. TSM server is at 5.2.2.1 on AIX 5.2, client is 5.2.3.1,on AIX 5.3 Could someone tell me what is happening here, and how to avoid this ? TIA.
