Direct Access File Independence Facility (VCKD)
VCKD Utility Programs
Backup/Restore Utility (VCKDBKRS)
The VCKD Backup/Restore program (VCKDBKRS) provides a convenient
method to convert Direct Access files from CKD to FBA devices. Each Direct
Access file on the original CKD disk is copied to tape using the BACKUP=xxxx
option. The RESTORE option reads the backup tape and constructs the new file
on the FBA disk.
CA Dynam does not have to be enabled to convert the original CKD files to
tape or from tape to FBA files, but the VCKDBKRS program must be available.
Control Statement Format

BACKUP=
RESTORE
MAP=
Specifies the device type of the file to be copied to tape. Valid entries are
2311, 2314, 3330, 3340, and 3350.
Restores the backup tape to the FBA disk.
Indicates track- or record-mapping. For more information, see Mapping FBA
Disk Files.
Default: Track mapping
CLEAR=
MAXSIZE=
EOF=Y
Identifies fill character enclosed in single quotation marks (C'c' for EBCDIC,
X'xx' for hexadecimal). If specified during backup, any unused space between
the last record and the end of the control interval will be filled with the
indicated character. If specified during restore, all assigned FBA blocks will be
cleared with the indicated character before restoring the backup tape. CLEAR
should always be specified during a restore run. The clear character does not
have to be the same for the backup and restore of the same file.
Specifies the maximum record size for variable-length records within the file.
Causes an EOF record to be placed after the last control interval when the
backup file is restored.
