Restores to an NFS share can fail if the NetVault Backup client's root user is not mapped to root on the NFS server. The files may be restored, but any permission changes from the umask will fail with an error like:
/file/name : Failed to chown - Not owner
On Linux, this can be caused if the option root_squash is set on the share, this is the default behaviour.
On Solaris, this can be caused if the root user of the NetVault Backup client is not explicity given in the shares access list.
On Linux, ensure the share's User ID mapping is set to no_root_squash.
On Linux, ensure that the NetVault Backup client is added to the 'root=accesslist' variable in the shares configuration.
