How does the Backup Policy feature work.
The backup policy feature will scan the entire network share that you have connected to and it will backup any files and subdirectories that the root user has access to.
If you find that you are missing files during the run of the backup policy, please ensure that you have "no_root_squash" set for your NFS shares and that the root user has read permission access to all of the files and folders that you wish to backup.
There may also be ACL permissions on the NFS share preventing root access, if that is the case, please ensure that you add ACL read access for the root user or if the root user is being mapped to another user (such as the nobody user), please ensure that user has read acl access.
