Retention settings

[vremenar]

Hi all.

I have a question about retention settings. I have to setup a retention to match the requirements of the business:
- documents that are "live" should have 14 versions kept on TSM servers for 90 days, last modified version should be kept on TSM for 10 years
- documents that are deleted should have only the last version and should be kept on the TSM for 10 years

Is this the right setup VERExists=14 VERDeleted=1 RETExtra=90 RETOnly=3650? Will that work for DB's (Lotus Domino and SQL Server)? Does that mean that only "live" versions older than 90 days will be removed from the TSM?

Thank you.

- documents that are "live"

TSM refers to those as Active.

Is this the right setup VERExists=14 VERDeleted=1 RETExtra=90 RETOnly=3650?

It will, but you may or may not be able to go back to 90 days that way. For example, if a file is modified daily and you keep 14 versions, you can only go back 14 days, you won't be able to go back 90 days. However if you have a file that is only modified once a week or less, you will be able to go back to 90 days, but you may not have 14 versions, especially if 14 were never created. Some files never change or only change once or twice during their lifetime.

Will that work for DB's (Lotus Domino and SQL Server)? Does that mean that only "live" versions older than 90 days will be removed from the TSM?

Active versions never expire, only inactive. To become inactive, one of the following needs to happen:
- for a file backup, a new version of the same object needs to be stored, the previous becomes inactive (VERExists adn RETExtra)
- for a file backup, the file is deleted and a new incremental flags it as inactive (VERDeleted and RETOnly)
- for a file or a TDP backup, the object is expired by the client (VERDeleted and RETOnly)

In the case of TDPs, all new backups have a unique sequence number, so are always unique objects, therefore always active. They need to be expired by the same mechanism that does the backup. You can look in the manual for the specific TDP you are using to see how to get rid of old backups.
