I'm a little late to this discussion, but there are a couple things I wanted to respond to:
> Thanks! That explains why I filled it up and how big it should be. Did > I miss it, or is it really not in book? > -Rob There is a section titled "DASD Space Needed for Control Data Backup" in Chapter 7 of the CMS File Pool, Planning, & Administration book. > The problem with that is if you have to recycle that filepool with the > control backups, the access will be gone and the control backup fails. > And I believe that unless you poke in the SFS server, you can't > re-access that other than STOP NOBACKUP and restart? > -Rob You can direct the control data backup to another file pool using the explicit directory name and thus, avoid the access, and the problem of th e access going away. Eg. fileserv defbackup disk backup data fpname:username.dir Backing up to tape is another method (besides minidisk).
