It sounds like you are trying to manage your backup tapes (as in traditional backup software -- like every other product out there); you should just let TSM manage the tapes -- if you have a failure on a daily incremental, you simply re-run it the next night (or sooner, if you are so inclined)... TSM will still only backup the new/changed files (assuming you are configured with the standard, typical situation). There are cases where a customer wants "full" backups more than just the first time a full-incremental is run -- but that is not typical, it's only because they are trying to consolidate mission-critical backups for the fastest restore, but there are better ways to accomplish that goal than re-sending the whole file system across the network (such as weekly image backup, and/or collocation on the file-level incrementals).
Your question suggests that you might greatly benefit from a better understanding of the progressive-incremental technology that TSM employs to back up file-served data; this product will use far fewer tapes to handle storing several versions of any given file, and (when configured properly) will manage the tapes and restore the data faster than its competitors. For example, with your 200 GB file system, it probably has thousands of files; using the "Getting Started" book, rule of thumb, you'd need only 200 x 5% x #-versions, (say 14 days point-in-time restore capability), 1.7 times the file space occupancy -- one full copy plus 5% for each additional day in your point-in-time restore criteria (guessing that less than 5% change per day across the most recent 14-day period). With TSM, there is no need to delete a specific day's backup of flat-file data, plain and simple; if that statement makes no sense to you, then you need a better understanding of the product -- your email is from IGS, so that would be highest recommendation. Now, all of this gets more "involved" when discussing backup strategies for large data base volumes; see the applicable TDP books and discuss with the dba's supporting the application to determine what's needed.

But what is the difference if I do full backups in between ??? If I see a filespace of incremental backups as one. I try to explain better my question. For example a I run a incremental backup every day, of the file of 200 gb aprox. If for any reason this backups fail, I want to delete this version, and reuse the tapes. Is possible this ? ... yes .. how ? Thank very much !!! Best Regards Christian Astuni IBM Global Services [EMAIL PROTECTED] Tel. 4898-4621 Hipolito Yrigoyen 2149 - Martmnez (1640) Bs.

No, you cannot delete a specfic day. However, you can setup your management classes to handle this, or do full between incrementals. 2. You will have to do a backup stgpool "stgpoolname" "copypoolname". You cannot set volumes from a primary stgpool offsite, only copypool volumes. Tivoli handles off-site copies using something called a copypool. This storagepool is normally only used for off-site and media protection purposes. If you haven't got a copypool, you will need to define one, to be able to handle off-site copies.

I have two question .... 1.- There are any way to delete a specific backup of one day or one week ? I running a incremental backups since Monday to Thursday, and archive on Friday. I want to delete all backups of a specific week. Do any people know how do this ? 2.- As I told ... a run backups every weeks, and every Monday I need to send offsite a group of tapes that I used in the last week. Is possible do this. I try to put the tape in status offsite, but I receive an error, that the tape "is not belong a copy storage pool" There are another way, because I stay a tape in normal status, this can be required in any time and I don't have this tapes. Thank You very much for your time. Best Regards. Christian Astuni IBM Global Services [EMAIL PROTECTED] Tel. 4898-4621 Hipolito Yrigoyen 2149 - Martmnez (1640) Bs. As. - Argentina
