Cc, An important consideration in restoring a file is understanding the retention settings of a copygroup and the distinction that two settings affect HOW MANY copies of a file are kept after they change or are deleted and two settings affect HOW LONG files are kept after they are changed or deleted.
VERExists - how many copies VERDeleted - how many copies RETExtra - how long to keep RETOnly - how long to Keep If a file never changes or is never deleted from the client, it will be restorable as long as it is not deleted from the TSM server - a nice benefit of the incremental forever method. As a general rule, for general filesystem backups, I keep all versions (VERE & VERD) but set limits on how long (RETE & RETO) deleted and changed files are kept. This way, if a couple of files are constantly changing, I can reliably roll back to any date within the retention time and restore any file. Again- this setting is something that varies with each environment. It may take a while to understand these settings and how they interact, I would suggest that you set up a test policy with short settings to observe how things work.

Hello, I'm new to TSM. I've been doing some reading on this TSM progressive incremental backup. My understanding with this backup, there is only one full backup (the base) and then incremental after that. Suppose I've been backing up a new server for 28th days, then I need to restore data backup on the 15th day, how do I restore all the data? Sorry for asking as I'm used to the conventional backup & restore method with Legato. Appreciate if someone can advice me.
