When doing NFS mount point backup, debug logs showing below error.
It's because NFS backup has Limitation:
ACL (Access Control List) attributes are not preserved. NFS does not support ACLs on remote files. Individual manual entries specify the behavior of various system calls, library calls, and commands. When transferring a file with optional entries over the network or when manipulating a remote file, the optional entries may be silently deleted

[61:1002] XXX reached its inactivity timeout of 12000 seconds. The agent on host will be shutdown
in this case, break down to small backups and set SmMaIdleTimeout/SmDaIdleTimeout/OB2IPCKEEPALIVE etc related parameters can help this.
