You can deploy a File Recovery Enabler for Linux (FREL) to serve as a Virtual Server Agent access node for VMware Cloud Director. The resulting Linux access node can be used for backups and restores of VMware Cloud Director virtual machines.
Note
Ensure that different Linux access nodes are used to protect your on-premise and cloud hypervisor workloads to avoid issues with the Commvault Communications Service (CVD) on access node. For example, if a Linux access node for VMware is configured as a MediaAgent for other workloads, then the backup and restore operations will fail.
Procedure
-
Download the V11 File Recovery Enabler for Linux (FREL) package from the Commvault Store.
This package provides an OVA template that is pre-configured with the Virtual Server Agent, MediaAgent, and uses the Mono framework.
-
Deploy the OVA template and configure the Linux machine as a File Recover Enabler for Linux (FREL).
For more information, see Deploying a File Recovery Enabler for Linux (FREL).
-
To reconfigure the FREL as a Linux access node, from the CommCell Browser, expand Client Computers > FREL_client, right-click Virtual Server, and then click All Tasks > Reconfigure.
-
Perform a remote install of all currently available Commvault feature release maintenance releases on the Linux machine.
Known Issues
-
For browse and restore operations, use a Linux access node and MediaAgent to browse Linux guests, and a Windows access node and MediaAgent to browse Windows guests.
-
Linux proxies get VM used space information from the vCenter, which might report a greater amount of used space than is actually used on NTFS volumes. This behavior can increase the guest size calculation that is used for capacity licensing. To avoid this issue, use Windows proxies for backups.
-
Find operations are only supported for backup operations that collect file and folder information. Find operations are not supported for backups performed using a Linux access node or for any hypervisor that does not support collecting file and folder information. Skipping page files is not supported when using a Linux access node for backups.
-
For backups, Linux proxies do not support metadata collection using the Collect File Details option. For guest file restores, you can use live browse to view and recover files.
Backups that are performed using Windows proxies do support metadata collection using the Collect File Details option.
-
A known issue in Mono 4.8 might cause backups to fail with one of the following errors:
TimerCallback() - Exception - Error: SecureChannelFailure (Ssl error:10000096:SSL routines:OPENSSL_internal:EXCESSIVE_MESSAGE_SIZE)exception - System.IO.IOException: Invalid parameter at System.IO.FileStream.Dispose (System.Boolean disposing)
