LIBR BACKUP/RESTORE
You can use BIM-EPIC to control the tape datasets created by the BACKUP function and
read by the RESTORE function.
Only prime dataset definitions are allowed. Therefore, multi-dataset tape groups are
specifically disallowed.
Each controlled dataset must be defined with a TLBL or DD statement.
LUB allocation must be inhibited since LIBR requires use of the SYS number specified in the
BACKUP or RESTORE control statement. In addition, the tape drive assignment must be
held after the dataset is closed since LIBR may attempt to access the tape drive even after the
close has been accomplished.
Only when including the Standalone Restore programs (RESTORE=STANDALONE) with
the BACKUP function, the first (or only) tape output volume must be allocated before the
BACKUP function is attempted by using the TSIDASS OPEN function.
Use the TAPELABEL parameter to specify a one to seven alphanumeric filename, the first
character of which must be alphabetic. This is the same filename reflected in the
accompanying TLBL or DD statement.
Due to LIBR restrictions, you cannot use GDI to route a tape backup to disk.
Many sample job streams for LIBR BACKUP and RESTORE are supplied when BIM-EPIC
is installed. Please see the BIM-EPIC Installation and System Guide, "BIM-EPIC Sample
Jobstreams".
