The second challenge with such
fast tape drives is that you cannot stream a modern tape drive that's placed behind a network backup server.
Other helpful features include a direct-drive chassis, which will provide
fast tape loading and reduced maintenance, and a selectable azimuth, which is a head selection process for playback of more than one VHS recording format.
The combination of post-process deduplication, most recent backup cache, and GRID scalability enables IT departments to achieve the shortest backup window, fast and reliable restores,
fast tape copy, rapid disaster recovery, and management of data growth without performance degradation or forklift upgrades.
The levels within the archive could be fast cache, slow cache (with binding capabilities),
fast tape, capacity tape, WORM tape separate from re-usable tape, and Iron Mountain or the equivalent.
A secondary or middle tier can be less expensive disk, optical, or even
fast tape, while tertiary storage is usually tape or optical.
In many instances,
fast tape drives have to frequently stop and wait, which can reduce the performance and drive reliability.
Linear Tape Open Accelis-Accelis ill be a 25GB, dual-hub cartridge, similar to the current IBM 3570 cartridge and will be built for speed, making for
fast tape access.
By keeping the most recent backup in its whole form and storing all previous versions as the byte-level changes (de-duplication), ExaGrid is the only vendor that offers rapid restore of backup jobs and
fast tape copy for offsite tapes -- unlike other solutions which require re-assembly of every backup job from millions, or even billions of small blocks tracked in large hash tables.
Small to medium-sized companies and larger enterprise departments will benefit from this product, as its
fast tape reads and writes enable the 6220i-b to handle larger data sets while completing back-up and restore tasks within a smaller time frame.
FalconStor's IPStor ZeroImpact(TM) Backup Enabler is used for
fast tape archiving of selected servers, leveraging the secondary data located on the storage appliance.
With an end-to-end throughput of up to 300 Megabytes per second, the 6240 provides
fast tape reads and writes to support larger data sets while completing backup and restore tasks within a smaller timeframe.
Other vendors charge users for add-ons such as Open File Managers, Database Agents, rapid disaster recovery and access to
fast tape drives.
