Tape is not dead and never will be. There are few reasons that keep it alive: cheap capacity, even comparing to modern high capacity SATA spindles, long-term vaulting capabilities that can last for decades, and regulatory requirements that a lot of companies or organizations are forced to adhere to.
Backup time doesn’t fit the backup window since the amount of data that needs to be backed up increases exponentially all the time. This is the main concern that traditional tape backup solutions have in common. Snapshots are taken when the system is under a light workload. Therefore, if the backup time is longer than the backup window, the backup processes overlap with production workload, which results in two negative consequences:
StarWind VTL seamlessly integrates into existing infrastructure and allows the backup process to fit the backup window. As the result, it creates an additional snapshot copy, meets regulatory requirements, significantly decreases backup cost and keeps the performance of the system stable by increasing the speed of the backup process.
