3 Different TSM Schedules required for the same AIX Client

[anandgmenon]

We have a requirement whereby we need to run 3 different TSM backup schedules on the same AIX Server as follows

1. Incremental Backup of all the local filesystems
2. Daily Full backup of a particular Filesystem
3. Hourly incremental Backup of a folder

Please explain how best this can be setup.

1. Is it possible to have different backup / archive retention settings for each of these schedules ???
2. Can these 3 schedules be part of different TSM Domains ??
2. If we do a full backup of a particular Filesystem daily , will this entire full backup be taken to DR via DRM daily?? Will each full backup be treated as a diffferent new version ???

1. Is it possible to have different backup / archive retention settings for each of these schedules ???

Schedule backup / archive is just that, a schedule job.

Yes, you can have different data retention for backup and archive.
There is a backup copy group and and archive copy group.

2. Can these 3 schedules be part of different TSM Domains ??

No. Like a node , a schedule can not be part of another domain.

2. If we do a full backup of a particular Filesystem daily , will this entire full backup be taken to DR via DRM daily?? Will each full backup be treated as a diffferent new version ???

Yes, when you do a full backup it will replace the most recent backup even though the file may not have changed since the last backup.
NOTE: If you do a full backup of a file system daily and if the file(s) does not change you have defeated the purpose of versioning.

1. I presume the way to get 3 schedules going for the same server will be to have 3 different stanzas in the dsm.sys file . please confirm

2. Each stanza will have a different node name . can these 3 node names be linked to three different domains ?? If not , how can we setup different backup policies for each of them ???

3. Regarding the full backup , suppose for the full backup schedule / node, we define a versioning as follows

verexist = 7
retextra = 7
verdeleted=2
retonly= 7

Will this imply that the full backup taken on every 8th day will expire the full backup taken on the 1st day ???

If the above policy does not do this , can you please suggest the policy settings which will do the above ???

Yes... got to have 3 different stanzas in the dsm.sys

SERVERNAME ABC

SERVERNAME ABC123
...

SERVERNAME XZY
....

2. Each stanza will have a different node name . can these 3 node names be linked to three different domains ?? If not , how can we setup different backup policies for each of them ???

The TSM Server see the 3 nodes as different systems.
The nodes can all be in the same DOMAIN or in different DOMAIN.

3. Regarding the full backup , suppose for the full backup schedule / node, we define a versioning as follows

verexist = 7
retextra = 7
verdeleted=2
retonly= 7

Will this imply that the full backup taken on every 8th day will expire the full backup taken on the 1st day ???

If the above policy does not do this , can you please suggest the policy settings which will do the above ???

No.
A full backup only done when the TSM Client backup to the TSM Server for the very first time.

Good Luck,

Admins sometimes tend to complicate things more than they need to, why would you want to run them under different node names? Just create alternate management classes that meet the required retention and use INCLUDES to bind the specific folders or file systems to the alternate retention settings. If you use three different node names then was the plan to run 3 schedulers? I have to disagree with this method...try to keep it as simple as possible. If you need more help I'll be happy to provide any information you need.
