This section explains considerations you should keep in mind when you restore file pools, user storage groups, file spaces, directories, and files.
CA VM:Backup does not group source and target pairs or check for duplicate source and target pairs in restore jobs. If you submit a restore job where the same source and target pair is specified twice or you submit the same restore request twice, CA VM:Backup restores that data twice.
You can restore SFS base files to a directory, a minidisk, or a virtual reader. You can restore SFS aliases and authorizations to directories only. Using restore job template files, CA VM:Backup system administrators can restore files for more than one user ID at a time.
When CA VM:Backup restores an SFS base file, the date of last reference is set to the current date.
You can restore BFS files to a BFS directory only.
When you restore a single file space through the Submit Special SFS/BFS Restores screens or the RSPACE command, the file space must already exist in the target file pool. When you restore multiple file spaces through the RGROUP or RPOOL command, you can specify either of the options listed below on those commands:
CA VM:Backup restores all file spaces regardless of whether they already exist in the target file pool or user storage group.
CA VM:Backup restores only those file spaces that exist in the backup version and not the target file pool or user storage group.
When restoring an entire SFS directory to an SFS directory that does not already exist, CA VM:Backup creates the directory and any required parent directories in the target file space.
When a system administrator uses the Perform User Functions screen to restore a directory and all subdirectories under that directory, the administrator must submit a restore request for each directory.
When CA VM:Backup backs up a DIRCONTROL directory, it does not include information about whether that directory is eligible to be assigned to a data space. When the directory is restored, any such eligibility is lost. To reinstate this eligibility to a restored DIRCONTROL directory, use the CMS DATASPACE ASSIGN command. For general information about using data spaces with SFS and for specific information about the DATASPACE command, see IBM's z/VM CMS File Pool Planning, Administration, and Operation manual.
For file and directory restores, the target directory must exist.
When you restore a user storage group, the user storage group must be defined in SFS and the minidisks that make up the storage group must be reserved and formatted. However, the minidisks can differ in number, size, and device type from those that originally contained the data. The file spaces do not need to be enrolled.
