Backup So Easy Even Your Users Can Do It: Page 9 of 20

The features that make remote backup viable in TSM have been available since version 4.1; the software is now at 5.2. There is no additional cost for this functionality, and the tools for managing remote systems are available in all versions of TSM version 4.1 and above. TSM licenses for laptops run an additional $65 per seat when added to existing installations.

Veritas Backup Exec 9.1 for Windows Servers, Desktop and Laptop Option Veritas offers a Desktop and Laptop add-on module for its server-based Backup Exec product. The complete package includes two main components: the Desktop and Laptop Option Administration Console, which can run on the Backup Exec media server or on any Windows system on the network, and the Desktop and Laptop Agent for client systems.

Veritas focuses on linking remote systems to an existing network share, where its enterprise backup methodology takes over. The client can run backups online or offline and can be invoked in four modes: manual as needed; scheduled at specific times; periodic (every 30 minutes, for example); and continuously, in which files are backed up as they're saved and closed.

Veritas' method differs in that it looks at mobile data as an extension of conventional network data, rather than as a standalone dataset. When the system is offline, the incremental backup data is stored in a local folder that allows users to restore recently backed up files without connecting to the server, and when the system is connected to the network, the user initiates a synchronization that refreshes the files on his or her network share.

The process of synchronizing remote data and "regular" network data lets you make files available concurrently to any network resource and is well-suited for users who need to work from a variety of desktops. Veritas uses a full file-level incremental backup scheme instead of byte- or block-level comparisons, so backup data that must be transmitted will be relatively hefty. However, the data-transfer agent is configurable to handle low bandwidth and interrupted connections, and backup data is secured through Windows user authentication as well as with optional 128-bit file-level AES encryption.
