Backup So Easy Even Your Users Can Do It: Page 8 of 20

The user interface provides two levels of complexity--a simplified basic interface and one with more advanced features for those with special requirements. An administrator's GUI provides a convenient interface for account management, user database analysis and other tasks. It also offers server administration tools to manage data across multiple BrightStor servers and supports migration of data to long-term tape storage on other ARCServ BrightStor backup servers. System reports include data growth, server activity, database analysis, file migration, and backup-and-restore logs.

BrightStor for Laptops & Desktops is available as a standalone product that can be integrated with CA's enterprise backup software. Pricing starts at $490 for the base client/server applications with a 10-user license; volume licensing is available.

IBM Tivoli Storage Manager Tivoli Storage Manager is an example of an existing enterprise application that has features for mobile systems. Portions of the TSM client for Windows can be configured to provide the same level of backup efficiency, file compression and encryption as dedicated remote backup client applications.

The key to Tivoli's remote backup capability lies in IBM's ASD (Adaptive Subfile Differencing) technology. The process begins with a full backup, with subsequent backups only for changed files. What makes ASD unique is that it uses a combination of byte-level incremental, block-level incremental, local caching and selective backup methodologies to calculate a backup scheme appropriate for files of all sizes. This reduces unnecessary processing overhead when comparing small files, while effectively decreasing backup data volume on larger ones.

TSM is a massive, multiplatform data-management environment, and because of its complexity, configuring the Tivoli Windows client to work as seamlessly as some of the dedicated remote backup applications will involve a bit of work. The client supports dial-up and broadband connections and uses 56-bit DES encryption, but the backups can be run only when the system is online.
