The transient nature of data that is staged to disk before being migrated to tape makes it a poor candidate for deduplication. The best deduplication ratios are achieved over time, so it's better suited when used in conjunction with longer term storage. The state of tape storage technologies and data backup todayĪlthough data deduplication works with disk storage, using the technology as a staging disk target with TSM is not a good idea. Otherwise, data migration to tape might be triggered automatically instead of on schedule and interfere with other processes.Ĭloud backup tutorial: How to leverage cloud backup services The disk pool(s) must be large enough to hold at least the equivalent of one night's worth of backup data that is directed to disk. Among other things, this allows for multiple concurrent backups that are not dependent on the number of tape devices available. Tivoli Storage Manager uses disk storage pools to stage backup data and then later migrate it to tape. The following are generally accepted best practices regarding some infrastructure design and implementation items specific to TSM. Beyond the basic requirements common to most backup products such as recovery requirements (RTO and RPO), network bandwidth, capacity, etc., some requirements are TSM specific due to its architecture. Sleep better at night knowing that IBM TSM is protecting your data.There are many aspects to consider when deploying a Tivoli Storage Manager (TSM) backup environment. Simply put, Tivoli Storage Manager is your enterprise solution to data backup worry.
