SMS and BACKUP

Backup uses SMS Storage Group and Management Class information to determine the eligibility of a data set for backup.

The SMS fields that CA Disk supports are as follows:

• Auto-backup (SG) — This required field can be defined Y or N. The default is Y. When this field is defined Y, CA Disk will automatically allow backup. When this field is defined N, CA Disk will not allow backup of any of the data sets for the Storage Group.
• Guaranteed Backup Frequency (SG) — This field can be defined 1 to 9999, or NOLIMIT. When this field is defined as a number, CA Disk will not allow more than that number of days to pass without backing up the data set. When this field is defined NOLIMIT, Management Class attributes will be used to process the data set. See the sysparm description for SMSGBRST99 in the Systems Guide for deletion of previous Guaranteed Backup copies when a new Guaranteed Backup is taken.
• Backup Frequency (MC) — This field can be defined 0 to 9999, or blank. The default is 1. When defined as number that number of days must pass before CA Disk will back up the data sets that have changed since the last backup. When this field is defined with a blank, other Management Class attributes are used to process the data set.
• Admin or User Command Backup (MC) — This required field can be defined BOTH, ADMIN, or NONE. The default is BOTH. When this field is defined BOTH, both the Storage Administrator and the user can explicitly back up a data set. When this field is defined ADMIN, only the Storage Administrator can explicitly back up a data set. When this field is defined as NONE, neither can explicitly back up. To define a Storage Administrator to CA Disk, use the SMSSTGAD sysparm.
• Auto-backup (MC) — This required field can be defined Y or N. The default is Y. When this field is defined Y, the data set is eligible for implicit backup. When this field is defined N, it is not. For example:

  SCAN REALVOLS
  SELECT SGNAME=/
  BACKUP
  

  accomplishes the following:

  • Select the volumes contained in all Storage Groups.
  • Select the data sets meeting the appropriate Management Class and Storage Group attributes.
  • Backup the data sets.
