Kenneth, just to give a bit more background, we are a development shop running Flex_ES and z/OS on an IBM x-Series machine for COBOL/CICS/DB2 development. We have around 250 GB of disk and our backups are currently done to a Super DLT drive that gives a maximum backup of 320GB with 2:1 compression. We run backups just once a week (BTW the disks are raid protected with both a hot and cold spare) and we take a mixture of full volume and logical dataset backups. We don't have any multi volume disk datasets. The belt and braces approach I have at the moment means that the backups will not now fit onto a single cartridge and the drive has no stacker. So I'm looking at the possibility of doing away with some of the logical dataset dumps if I could use the full volume ones to restore individual datasets. Apart from normal sequential and pds type stuff the other main dataset type would be DB2 tablespaces. And lastly (and I know this should not influence any change of plans) I can't remember the last time I had to do a restore.

Jim, You won't find any product can restore a multivolume dataset from just one volume backup. You can work hard to restore the individual pieces and then hope you catalog them in the right order. Maybe for VSAM too if you work at the component level, not the cluster. Haven't tried lately. Then go and do a define recatalog. But you really need to be depserate to do that. Full volume dumps were meant for full volume restore. Incremental dataset level backups give you dataset recovery. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
