VAMI backup fails with error "BackupManager encountered an exception".

Products

Issue/Introduction

VAMI backup using NFS fails with error "BackupManager encountered an exception. See logs for details".

In /var/log/vmware/applmgmt/applmgmt.log on the vCenter we see the following error:

failed. rc: 32, stdout: , stderr: mount.nfs: Failed to resolve server NFSServerFQDN: Name or service not known

Environment

vCenter 8.x

Cause

Possible issue relating to DNS for the IP/FQDN of the NFS server.

To confirm, open an SSH session to the vCenter, log in with root credentials and run the following commands:

nslookup NFSserverIP

nslookup NFSserverFQDN

If the above forward/reverse lookup fails, check the DNS configuration.

Resolution

In the VAMI backup settings use the IP address of the NFS server instead of the FQDN to do the VAMI backup.
