Expansion is supported on Unitrends Enterprise Backup deployments.
Warning: Once you add a disk to the datastore and expand storage, that disk is added to a logical volume. The newly added disk and any existing disks are then treated as one disk by the system. You cannot remove the disk once it has been added. Removing a disk after expanding storage results in data loss and corruption. |
1 Verify that no backups are running. If backups are running, either cancel them or wait until they complete.
If you attempt to add storage while backups are running, the Administrator Interface displays the following message: A storage expansion cannot take place while backups are queued or running.
2 Add a disk to the datastore used by the Unitrends Enterprise Backup VM.
See To create additional backup storage for Hyper-V or To create additional backup storage for VMware for details.
3 In the Unitrends system, select Settings > Storage and Retention > Storage.
4 Click Add Backup Storage.
5 Choose Expand your backup device across added disks, then click Confirm.
• The Expand Storage page shows the current size of the default internal storage pool.
• If you have not yet added a datastore, you may click Show Steps for Adding Additional Storage for detailed instructions. You must go to your hypervisor and add the datastore before expanding storage.
6 Click Expand Storage.
The system expands storage on the default device to include the disk you created on the datastore. The default device is D2DBackups unless you’ve configured a different one.
7 When storage expansion is complete, the current size of the storage pool is updated to reflect the expansion.
95% of the disk you added is allocated for backup/replication storage. 5% of the expanded storage, up to 2GB, is allocated for swap space.
8 Click Confirm to exit.
