Specifying Change Detection

To indicate how CA VM:Backup identifies when data changes between backups, use the Change Detection section of the Work with Backup Template template screen. Depending on the backup type (full or incremental), CA VM:Backup reacts differently to your criteria for detecting changes.

• For a full backup, CA VM:Backup uses the change detection selection to determine what to save in the catalog to use for comparison during an incremental backup. This comparison detects whether data has changed.
• In incremental backups, CA VM:Backup uses the change detection selection to determine what values to compare to the values stored in the catalog. This comparison of values determines whether data has changed.
