Transparent Snapshot Data Mover protection mechanism
The
Protection Engines window in the
PowerProtect Data Manager UI includes a pane for
Transparent Snapshot Data Movers. Transparent Snapshot Data Mover (TSDM) is a protection mechanism that is introduced in
PowerProtect Data Manager 19.9 for data movement during virtual machine protection operations. Previously, the only protection mechanism available in
PowerProtect Data Manager for virtual machine protection was the VMware vStorage API for Data Protection (VADP).
A vSphere Installation Bundle (VIB) is included with the software installation and update packages for
PowerProtect Data Manager 19.9 to facilitate the use of TSDM, and is enabled at the vCenter level upon the
PowerProtect Data Manager 19.9 installation or update. The VIB installation occurs automatically at the cluster level when a virtual machine protection policy is created, with no requirement to restart the ESXi hosts or put the hosts into maintenance mode. Any new virtual machine protection policies use TSDM as the default protection mechanism instead of VADP, provided that the vCenter/ESXi Server that hosts the virtual machines is a minimum version of 7.0 U3.
The
Transparent Snapshot Data Movers pane provides a hierarchy view of the vCenter Server asset sources that have been added in
PowerProtect Data Manager. Use this view to determine if the vCenter/ESXi is enabled for VIB management, and if the hosts have the VIB installed or are eligible for VIB installation. A vSphere host cluster can have one of the following statuses:
Installed—The VIB installation on this vSphere host is completed, and TSDM is enabled as the default protection mechanism for the virtual machines on the vSphere host.
Ready for install—The vSphere host requirements for VIB installation have been met, and the installation will proceed automatically on the vSphere host when a virtual machine running on the cluster is added to a protection policy.
Ready for upgrade—This status displays when the VIB is installed on the vSphere host and
PowerProtect Data Manager is upgraded, but the VIB is being managed manually. In this case, the VIB will not be upgraded automatically on the vSphere host.
Not eligible—The vSphere host does not meet the requirements for VIB installation. When TSDM cannot be used, the VADP protection mechanism is used for virtual machine protection operations on this host.
Failed—The VIB installation on the vSphere host did not complete successfully. The
Jobs window provides more information about the issue that caused the failure.
Use the filter icon in the status column to display only vSphere hosts with a certain status. For example, you can choose to display only hosts that are ready for VIB installation or upgrade.
When the VIB installation is started, the
Protection Engines window updates to display the progress. Also, an entry for the job
Performing Host Configuration (vib_install) appears in the
Jobs window.
NOTE Any virtual machine assets that were added to a virtual machine protection policy in
PowerProtect Data Manager 19.8 and earlier currently use the VADP protection mechanism. After the VIB installation on the vSphere host that contains these virtual assets, you can migrate these assets to the TSDM protection mechanism.
Migrating assets to use the Transparent Snapshot Data Mover provides more information.
Disable or re-enable VIB on an ESXi host
In the
PowerProtect Data Manager UI, you can disable VIB management on a vCenter to prevent automatic installation or update of the VIB on the ESXi host. To disable VIB management on the vCenter:
Go to
Infrastructure > Protection Engines, and then select the
Transparent Snapshot Data Movers pane.
Hover over the
Enabled icon to the right of the vCenter, and then click
Disable.
To re-enable VIB management on a vCenter that currently has the VIB disabled:
Hover over the icon to the right of the host, and then click
Enable.
If a VIB installation or update is required, the status indicates
Ready for install or
Ready for upgrade.
Select the checkbox next to this host and click
Install to manually perform the VIB install or update, or wait for the automatic VIB installation.
When performing a manual VIB installation, if one or more of the selections are not eligible or the VIB is already installed, a dialog appears. Click
OK to proceed.
