Items will not be backed up unless the folders are available.

One or more of the items selected to be backed up were not included because the folder is not available. You must make the items available or remove them from Server Backup.

If the missing items are intended to be backed up, you must ensure that the hard drive on which the items are located is physically connected to the server and turned on.
