The NetBackup Desktop and Laptop Option (DLO) provides automated file protection for desktops and laptops (collectively referred to as desktops). Protection is provided whether the computer is connected to the network or offline. When the desktop is not connected to the network, the files are backed up to a user data folder on the desktop. When the computer reconnects to the network, the files are backed up from the local desktop user data folder to the designated network user data folder.
Users who have multiple computers can synchronize the data between their computers so the most up-to-date file versions are available on all of their computers.
Domains and active
The DLO Administration Server and DLO Storage Locations must be in a Windows Domain or Active Directory. Computers running the Desktop Agent can be outside of a Windows Domain or Active Directory, but they must authenticate with the domain or directory to access the DLO Administration Server or Storage Locations.
DLO can be treated as a network file server. The ideal server for DLO has a fast network connection and a fast set of disks. The CPU is not as critical as these other factors for the DLO file server. The number of Desktop Agents that can successfully back up to one DLO installation depends on many factors. Multi-client testing of DLO has found that when there are more than 400 clients concurrently attached to a DLO server running Windows 2000 Advanced Server, file operations may begin to fail when Paged Pool memory runs out. For this reason, it is not recommended to configure DLO to run more than 400 concurrent backups of this size when using DLO with Windows 2000. This limitation was not observed when running DLO with Windows 2003.
The DLO Administration Console can be managed by any user who has full admin rights on the DLO Administration Server where DLO is installed. The user's account must be a domain account and must have rights to create network shares and manage permissions of network shares and directories on any remote server used for Storage Locations or network user data folders.
