Delayed Archiving for Existing Clients

Delayed stubbing prevents data loss in the event that you must perform a disaster recovery (DR) restore. Without delayed stubbing, when you perform a DR restore, recalls might fail for files that were backed up after the DR backup that is selected to be restored. By delaying stubbing, you can roll back to a previous CommServe DR version (within the minimum DR backups setting) without any data loss.

Stubbing is delayed by the number of DR backups plus the number of days that must pass after a DR backup.

  • For existing client computers, the default vales are set to one (1) DR backup + zero (0) days.
  • Starting Service Pack 16, for new CommCell environments, the default values are set to zero (0) DR backup + zero (0) days.

You can change the number of DR backups and the number of days to delay the stubbing process by configuring the nMinDRBackupBeforeStubbing (DR backups) and nMinDaysBeforeStubbing (days passed) additional settings at the CommServe level.

Both the additional settings are required for delayed stubbing. To disable delayed stubbing, set the value of both additional settings to 0.
