Failed to mount restore point. Linux FLR appliance deploy failed in Veeam

Issue

Some times when we try to restore the Linux VM and its environment folders/files (Guest OS level), we get below error,

 
Error

Failed to mount restore point. Linux FLR appliance deploy failed :
Failed to mount NFS volume (IP_of_Repository:/VeeamBackup_IP_of_Repository). IP_of_Repository: Fault "PlatformConfigFaultFault", detail "NFS mount IP_of_Repository:/VeeamBackup_IP_of_Repository failed:
Unable to connect to NFS server."


Actual issue is,

Linux FLR server and restored Network File System (NFS) server connectivity issue.

Solution

1.Check the connectivity issue and open connection between FLR server and NFS server.

2. Time being change the NFS server which is accessible from FLR server. You can change the settings from veeam B&R server.

Infrastructure --> Repository --> Properties --> NFS server name (change in to another Veeam Repository as NFS server).

Note : Here, Repository is mentioned as Storage server/device name.

Root cause of this issue is,

Look likes firewall has issue, and it turns out it was.

Solution

Enable the rule Remote Service Management [RPC-EPMAP]. This will allow the job to continue. This rule is disabled by default in Windows server 2016, but previous version this rule might enabled by default..
