This feature allows two backup jobs to run at the same time, if they meet the backup type and combination criteria.
For SQL Continuous backups, the Concurrent backup option will appear in the left menu when editing the job. This option only shows for SQL Continuous jobs. File Archiving backups enable Concurrent backups under Zip Options.
To enable concurrent backups for SQL Continuous:
- Select Concurrent backup from the left menu.
- Select Enable concurrent backups from the Concurrent backup page.
Considerations
Concurrent backup combinations:
- Two File Archiving backup jobs can run at the same time if both have ‘Enable concurrent backup’ selected.
- An SQL Protection backup job, with ‘Enable concurrent backup’ selected, can run concurrently with a System Protection, File Protection or File Archiving backup job. The File Archiving backup job does not need to have ‘Enable concurrent backup’ selected. (System Protection and File Protection do not have an ‘Enable concurrent backup’ option).
- An SQL Protection backup job can run at the same time, in any combination, if both have ‘Enable concurrent backup’ selected.
- In all cases, only two backup jobs can run concurrently.
Concurrent backup scenarios:
- If two concurrent backups are scheduled to start at the same time, one backup will start first and begin preparing the job. Once the preparation phase has completed, the second backup will start
- If a third scheduled backup job has 'Enable concurrent backup' selected, it will be queued and run once one of the two existing concurrent backup jobs has finished.
Concurrent backup limitations:
- Only two backup jobs can run concurrently.
- Concurrent backups cannot write to the same destination device (e.g local drive, NAS, RDX etc).
- If another backup job is already running when the concurrent backups are scheduled to start, then one of the concurrent backups will start if it meets the criteria defined in the concurrent combinations section.
- A backup job cannot run concurrently if it is backing up a Hyper-V environment or an Exchange server using VSS (VSS enabled).
