For SMB and Enterprises, who either look to get rid of backup tapes completely, or are willing to accelerate backup process and add an extra level of protection, our solution is StarWind Virtual Tape Library (VTL). It is an appliance that eliminates the need in physical tape and “pretends” to be a supported tape drive or autoloader, keeping all data on inexpensive, fast and high-capacity spinning disks.
Even with explosive data growth, StarWind VTL fits the backup into backup window by accelerating it, so the process does not overlap with production time. Optionally, it creates additional copy of backup data for better safety. It is also available in a software-only form, as part of StarWind VSAN functionality.
StarWind VTL targets those, who need to replace existing tape backup infrastructure or accelerate it if regulatory requirements prohibit replacement. In case the goal is just virtualizing tape backup or creating a stretched backup infrastructure, StarWind Tape Redirector will come in handy.
StarWind VTL utilizes multi-tiered RAM and flash caches to accelerate backup performance. Using inexpensive conventional RAM, SATA SSD, MLC flash or so for caching, it allows to have bigger caches for the same money. StarWind VTL keeps backup performance exceptionally high, easily fitting it into backup window and avoiding overlapping with production time.
Data Deduplication and Compression
StarWind VTL uses data deduplication to reduce space usage and conserve disk capacity. It fully supports Microsoft Windows deduplication engine and StarWind Virtual SAN own space reduction technologies. Apart from capacity savings, these technologies also give a boost in performance, reducing the amount of data required for transfer.
Hardware Agnostic and Commodity Hardware
StarWind VTL uses commodity servers and faster and cheaper high-capacity SATA HDD to emulate traditional tape hardware: drives, libraries and autoloaders. It cuts down the cost of backup and accelerates performance, because backup process takes less time, without overlapping with production.
Scale-up and Scale-out
StarWind VTL employs Scale-Up and Scale-Out to meet task demands with constantly growing backup data. Capacity can be increased by simply throwing more spindles into the existing storage node. Adding new nodes will balance workload between them and avoid performance degradation.
