Backup Type

Use the Backup Type field to select one of the following four backup formats: Logical, CMS, CMSALLOC, or Physical.

Note: CA VM:Backup always backs up SFS file spaces in SFS format, regardless of what you specify in this field.

Logical

CA VM:Backup determines the best way to back up data based on the type of domain being backed up. (See the following table.) This option is the default.

Type of Domain	Backup Format
CMS minidisk	CMS format
BFS file space	BFS format
Non-CMS minidisk	Physical format
Recomputed minidisk	CMS format--CMS area Physical format--Recomputed area Note: A recomputed (recomped) CMS minidisk is a minidisk that has been formatted with the RECOMP option of the CMS FORMAT command.
Reserved minidisk	Physical format Note: A reserved CMS minidisk is a minidisk that has been formatted with the CMS RESERVE command.
SFS file space	SFS format

CMS: CA VM:Backup backs up all CMS minidisks in the same manner as a logical backup, described previously. Non-CMS minidisks are not backed up. For reserved minidisks, CA VM:Backup performs a physical backup of the entire minidisk.
CMSALLOC: CA VM:Backup reads the block allocation map on CMS minidisks to identify which blocks are free or active. CA VM:Backup physically backs up only the blocks that are in use. Non-CMS minidisks are backed up physically. If you specify CMSALLOC in a full or incremental backup, CA VM:Backup automatically performs a full backup.
Physical: CA VM:Backup determines the disk type of the minidisk, then performs a physical backup accordingly. CA VM:Backup backs up CKD minidisks by track, and FBA minidisks in groups of 32 blocks of 512 bytes.
