TSM 6.3 Node Replication - Using nodegroups to make it easy.
Tivoli Storage Manager from 6.3 onwards has had a feature called node replication. This brings up a new command called “replicate node”. The only pre-requisite is that you have two TSM servers on version 6.3 or above, and server-to-server communications are configured. The command replicate node, can replicate an individual node, or a group of nodes. I would strongly recommend using node groups, because you can have a single group containing many nodes, then have a schedule to replicate the group. Having a schedule for each node to be... [More]

Managing TSM Database Backups
Recently I was looking at a TSM server, and could see that TSM database backups to tape were working and expiring without issue, however database backups taken to disk were not being removed, and filling up the filesystem. There are three types of backups you can take of the TSM database: - Full. This is a full backup of then entire TSM database and this will truncate the TSM server active and archive logs. - Incremental. This will backup the changes in the TSM database between the current point in time and the last full database backup. -... [More]

TSM file level backups - how the retention settings work
The most powerful thing about TSM is how flexible it can be. There is a way for TSM to meet pretty much any data management requirement. The difficult part is to work out how long you need to keep data for, what rules need to apply. Once you know that setting up TSM is just a matter of following the motions. TSM performs backups and archives. (as well as restores and retrieves!) - Backup is typically the file level "incremental forever" type backups. - Archive is a full backup (eg a monthly backup) to keep for X amount of days.... [More]

Backing up JFS2 snapshots with TSM
There is a really good article here about how to create JFS2 snapshots in AIX: http://www.ibm.com/developerworks/aix/library/au-jfs2_snapshot.html This is a good way to get a point in time copy of an AIX filesystem, if your storage system doesn't have the capabilities of taking snapshots. The next problem is that of backing up the snapshots to TSM, and having your filespace naming correct. If you take a backup of /data by taking a snapshot of /data, and mounting it on /mnt/data that means that the TSM knows about /mnt/data which makes the... [More]
