Okay, I may rely on mirroring then. If I do a DB backup every 4 hours it'll cost 6 tapes a day and each one will only have a few MB of data.
For some reason, the tapes used for DB Backup aren't listed when I execute a Q VOL. Something else to investigate. Thanks again. -----Original Message----- From: PAC Brion Arnaud [mailto:[EMAIL PROTECTED] Sent: 21 September 2006 16:28 To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] Total newbie question about DB Backups Hi Angus ! You'll probably get somehow disapointed, but there's no way to do what you're asking ! TSM wants a new tape for each DB backup, and the only way to spare your precious scratch volumes would be to use some form of disk storage, thru the mean of a sequential-on-disk device class ... HTH.

Every DB backup seems to use another scratch tape so my 3582 is going to run out of tapes very quickly. My backup command is Backup DB type=full devc=lto2-dc lifted directly from the redbook. How can I limit the number of tapes used for DB backups? I tried limiting the backup to a particular tape volume but the tape is apparently in use after the first backup and cannot be reused. Angus
