Please bear with me, but this is an area where my knowledge is very limited.
I'd need a quick and simple answer for a discussion here. Don't go too much into various possibilities. I just need to get the big picture for now. Snapshot functionality is offered by DASD subsystems, not by z/OS, right? What granularity can one get with snapshorts? - On the sub-volume level, i.e. on the individual MVS data set level ? - On a multi-volume level within one storage subsystem? - On a multi-volume level within multiple storage subsystems? -How can an application access the data in a snapshot, i.e. to create a point in time backup? -Is it reasonable to program, say in Java or PL/1, to backup data with the help of snapshot technology? - Does this require authorized functions? -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
