Specify Miscellaneous Options for Disk Staging Backups

To perform disk to disk to tape (B2D2T) backups, you can optionally specify policies that control how Arcserve Backup processes backup job data.

Note: The miscellaneous options specified for disk staging backups apply to file system devices and deduplication devices.

To specify miscellaneous options for disk staging backups

1. Open the Backup Manager and select the Policies tab.

   Click Miscellaneous in the policies list.

   Specify the options that follow that you require for the job:

   • Purge canceled sessions from disk--Use this option to direct Arcserve Backup to delete sessions from the staging device immediately after a backup to staging device is canceled.

     This option helps to reclaim free disk space on the staging device as quickly as possible.

   • Purge failed sessions from disk--Use this option to direct Arcserve Backup to delete sessions from the staging device immediately after a backup to disk staging device fails.

     This option helps to reclaim free disk space on the staging device as quickly as possible.

   • Create makeup jobs to back up data directly to final destination under disk full conditions--Use this option to direct Arcserve Backup to back up data directly to its final destination media if there is insufficient free space on the file system device in a staging group.

     A backup operation will fail if there is insufficient free disk space on the staging device. To remedy this situation, Arcserve Backup can divert the backup operation from the file system device in a staging group directly to the final destination media. A makeup job searches for blank media and media from a scratch. As such, specifying this option can increase the overall success rate of your backup operations when a "disk full" condition exists.

   • Create makeup jobs on hold if Data Migration jobs fail--Use this option to direct Arcserve Backup to create makeup jobs on HOLD if data migration (copy to tape) jobs fail.

     A data migration job can fail if a media or tape drive error occurs during the copy to tape operation. Use this option to create a makeup job with a HOLD status that you can change to a Ready status after correcting the tape drive or media errors. If an error condition exists, this option minimizes the need to create tapecopy jobs.

   Consolidate Data Across Jobs While Copying Options

   Lets you consolidate backup data during the migration operation.

   • Copy Method--Specify a copy method (Append or Overwrite) that you want to use for the consolidation operation. The method that you specify must be the same for all jobs that you want to consolidate.
     • If you have a requirement to consolidate data across multiple jobs and ship the tapes on a daily basis, you should choose the Overwrite option.
     • If you have a requirement to consolidate data across multiple jobs (for daily backups) for the whole week to a single tape and ship the tapes on a weekly basis, you should choose the Append option.
   • Limitations and Considerations
     • If the backup is a rotation or a GFS backup, you must specify the prefix of the target media and the prefix of the media pool that you want to use for consolidation on the Destination tab.
