Can I add a comment... What if you have some form of file system corruption from anything and the file appears to have changed, TSM backs up the corrupt version and purges off the old copy??? If the files are as you say and never change, you won't have any inactive versions as long as active versions exist and if a file is accidentally deleted you would want some time to recover...
In looking at your current settings, from a business point of view, they are very sound and (if the files are as you say) you will only have one copy of the data, until something is deleted and then you will have 60 days to figure out someone incorrectly deleted a file and recover it. Again, if those files never change, your existing config will only have a single copy of the data... the current/active version.

I am going to change the backups from the incremental-forever to image backups. Also, I am going to change the retention to where I would only keep the active copy of each, and that's it. I don't want any inactive copies, and I don't want to keep them around for ANY amount of time, only the active. Reason being, the files in those NTFS file systems never change, and they are only archives. Here is the current config Versions Data Exists 2 Versions Data Deleted 1 Retain Extra Versions 30 Retain Only Version 60 Based on my comments above, would that need to be?: Versions Data Exists 1 Versions Data Deleted 0 Retain Extra Versions 0 Retain Only Version 0 Please help...This is one of the parts I hate about TSM. I know it's probably simple, but I never can seem to remember what each retention parameter (as shown above) MEANS! J God bless you!!!
