SELBKUP is short for selective backup. It creates a backup of one named member. To backup more than one member, you can submit a series of control cards.
►►─ SELBKUP ─ memname ────────────────────────────────────────────────────────►◄
Specifies the SELBKUP function.
Name of the member to back up. For instructions to format the member name, see HEX Function.
Example
To selectively back up version 5 of a panel called SELBKEX in system $ID, enter:
HEX / SELBKUP $IDSELBKEX/4040404040404040/005U
Use the sample JCL displayed in the description of the BACKUP statement as a model. You must create one SELBKUP card for each member to back up. Arrange the cards so that member names are in ascending alphabetic order. VLSUTIL ignores any card that is out of sequence. You can submit any number of cards. The backup file has a ddname of VLSBKUP. Except perhaps for its size, there is no difference between the backup file produced by SELBKUP and the backup file produced by BACKUP.
You can use this backup file as input to a RESTORE function. However, if you specify RESTORE without operands, the VLS library contains only the members named in SELBKUP statements. To add the selected members and preserve the existing contents of the library, use the RESTORE NOCLEAR function. To preserve the existing contents of the library and add the selected members but replace members that have the same name, use the RESTORE NOCLEAR(R) function.
In most cases, the backup file produced by SELBKUP is used as input to a selective restore (SELREST). The SELREST function preserves the existing contents of the library. Use SELREST with SELBKUP to move selected members from one VLS library to another.
