Message: the server is not allowed to write to the client's file systems
Explanation: The client does not allow writes from the server.
Recommended action: Perform the following to perform restores or install software from the server.
On a UNIX client, delete DISALLOW_SERVER_FILE_WRITES from the /usr/openv/netbackup/bp.conf file.
On a Microsoft Windows or NetWare nontarget client, select Allow server-directed restores on the General tab in the NetBackup Client Properties dialog box. To display this dialog box, start the Backup, Archive, and Restore interface on the client and select NetBackup Client Properties from the File menu.
On a Macintosh client, delete DISALLOW_SERVER_FILE_WRITES from the bp.conf file in the NetBackup folder in the Preferences folder.
On a NetWare target set ALLOW_SERVER_WRITE to yes in the bp.ini file.
