Continuous Restore mode for virtual disaster recovery
You can perform virtual disaster recovery on request or set it to the Continuous Restore mode when data recovery is synchronous with backups performed in the source system.
The Continuous Restore requires a dedicated computer or virtual machine that must not be used for other purposes (learn more).
Enabling the Continuous Restore mode
Backup Manager instructions
- Set the Backup Manager to the restore-only mode (if it is not installed in the restore-only mode).
- Go to Continuous restore > Virtual disaster recovery.
- Click Enable continuous restore.
- Select a recovery target and configure your recovery preferences. Click Restore.
Recovery Console instructions
The Continuous Restore mode is the predefined option in the Recovery Console. You can manage the setting for each device through the Continuous Restore checkbox.
The target virtual machine is not supposed to be in use while the Continuous Restore mode is active. If your recovery software detects that the virtual machine was started in-between restore sessions, further restores get blocked and a warning message appears. This is done to prevent possible data loss.
There are several ways to unblock the Continuous Restore process.
- Click the Unblock button in the warning message.
- In Backup Manager, go to Continuous restore > Virtual disaster recovery and then click Restore. This will initiate a quick delta restore that will overwrite the changes at the target location (if any).
- In the Recovery Console, right-click the device and choose Unblock from the context menu.
After this is done, the continuous restore process will be fully functional again.
If the virtual machine may contain changes that you want to keep, please make a copy of it before you unblock the Continuous Restore mode.
The recovery software checks if the virtual machine has been in use before each virtual disaster recovery session. If you are sure no important data is added to the virtual machine, you can disable these checks and have the previous version overwritten without warning messages. To do it, add
VdrRestorePolicyForceOverwrite=1 to the
[General] section of the configuration file belonging to your recovery software.
The setting applies to all backup devices installed on the current computer (one device for the Backup Manager or multiple devices for the Recovery Console).
