Operations:
 1. Handle several VSE/VSAM files with a single command, either with a generic
name or as files of one catalog.
 2. Restore VSE/VSAM files to locations, volumes, and device types that are
different from those where the files were before.
 3. Exclude files from a collective backup or restore operation.
 4. Tune the performance of VSE/VSAM by specifying the size of the buffer in the
BACKUP command, and the number of buffers in both the BACKUP and
RESTORE commands.
In addition, the VSE/VSAM Backup/Restore Feature allows you to:
Back up and restore empty objects, where an empty object may be either a:
VSE/VSAM object defined with NOALLOCATION (such as a default model
or a dynamic file), or
VSE/VSAM cluster that has not been loaded since being defined or reset.
Change the allocation size for the data component of a file at restoration.
You can specify allocation size in device-independent units by using the
RECORDS parameter when the cluster is defined to facilitate restoration of
objects.
Change the index CI-size at restoration.
