Access "Making disk-based backup work"
This article is part of the Vol. 3 No. 7 September 2004 issue of A look inside Hitachi's TagmaStor high-end arrays
Does your backup software do disk? Here's how three leading backup software applications deal with disk. IBM Tivoli Storage Manager (TSM) was designed to include disk as a key element, using a hierarchical model that maps directly to the "disk as cache" approach. The normal process in TSM is to back up to disk and then migrate to tape in an automated manner. Multiple read and write access is permitted to disk storage pools. High-water marks identify capacity boundaries that will force data migration to the next level in the storage hierarchy (usually tape). Data is migrated from disk to tape on a scheduled basis outside the normal backup window. Because TSM is optimized for a continuous incremental model, hybrid backup approaches aren't applicable. Other disk-based approaches may be used as well, but none have the same degree of built-in support. Legato NetWorker has supported disk-based backup since Version 5; its file device type supports writing backup savesets to disk in essentially the same format as it writes to tape. Version 7 significantly enhances ... Access >>>
