A tape cartridge is very small and thus a large volume of data can be stored in a very small place, especially important if you are paying for offsite storage in a bank vault or fireproof safe. Because the tape is removable makes it possible to store the data separately from the system, which provides protection from everything from viruses to destruction of the site.

When stored under the right conditions, tape media remains readable for at least 10 to 15 years, and some tests have shown it to last up to 30 years. Not meeting Backup Window What they do today Gamble – run risk of losing data Impact production environment – accept lower performance until backup jobs have completed In many companies, nightly backup reports are delivered up the IT management infrastructure. Excessive backup failures (either on success rate or SLA basis) have visibility How the VLS solves the problem Accelerates backup performance by allowing more jobs to happen at the same time s
