Instructions
Enable or disable Changed Block Tracking (CBT)
The Changed Block Tracking (CBT) feature is used to identify areas of the virtual machine backup that have changed since the last backup and only process those changed areas during the next backup. CBT is enabled by default.
Steps
1. From the PowerProtect Data Manager UI, select Infrastructure > Assets.
2. From the Assets window, select the Virtual Machine tab. If a policy has been assigned, the table lists the virtual machine assets that have been discovered in the vCenter, along with the associated protection policy.
3. Select one or more virtual machine assets from the list, and click More Actions > Changed Block Tracking.
The Changed Block Tracking dialog box appears.
4. Clear the check box to disable CBT, or select the check box to enable CBT.
In some cases, CBT can cause backups to take longer than expected if there are high change rates on the virtual machine.
You can disable CBT for virtual machines if the backups are taking too long to complete. Also, if you encounter an issue with CBT, you can disable it on the virtual machine.
NOTE: If CBT is enabled in PowerProtect Data Manager but is disabled in VMware vSphere, PowerProtect Data
Manager tries to back up the virtual machine with CBT enabled. If PowerProtect Data Manager cannot enable CBT, the
backup completes with a warning that indicates CBT data is not available.
5. Click Save.
NOTE: When CBT is disabled for a virtual machine, subsequent backups no longer use CBT.
Ad-hoc replication jobs for urgent scenarios
You can perform replication of one more protected assets within a protection policy by using the Protect Now functionality in the PowerProtect Data Manager UI.
NOTE: VMAX storage groups only support MTree replication, which is performed and scheduled from the DD system.
Therefore, manual replication for assets in a VMAX storage group is not supported.
To perform manual replication:
1. From the PowerProtect Data Manager UI, select Protection > Protection Policies
2. Select the protection policy that contains the assets that you want to replicate, and click Protect Now.
The Protect Now wizard appears.
NOTE: The protection policy must be enabled, its purpose must not be Exclusion, and the policy must already be
configured with a replication stage.
3. On the Assets Selection page, select whether you want to replicate all assets or choose individual assets that are defined in the protection policy, and then click Next.
4. If you selected the option to choose individual assets for manual replication instead of all assets, the Assets page appears with the individual assets available for selection. Select the assets that you want to include in the manual replication, and then click Next to display the Configuration page.
If you selected to replicate all assets, the Configuration page appears.
5. On the Configuration page, select Replicate now, and then select from the available replication stages.
NOTE: Only replication stages for the primary backup are available for selection.
6. Edit the retention period if you want to change the default settings, and then click Next.
The default settings are inherited from the primary backup stage of the parent protection policy.
7. On the Summary page, review the settings and then click Protect Now. A notification appears indicating whether the
request was processed successfully.
