iSCSI D2D2T Disk Based Virtual Tape Library Backup Solutions

D2D2T Disk Based Backup Solutions

	D2D2T Backup Cybernetics' HSTC™ is a stunning breakthrough in data protection. Designed with incredible flexibility for adapting to your environment and for evolving with your growing network or enterprise, our High Speed Tape Cache capitalizes on the power of virtualizing extremely low cost, ultra-fast disk storage to create numerous virtual tape drives and tapes. The HSTC™ supports multiple host initiators with independent, iSCSI and SCSI interfaces, for virtually limitless configuration possibilities. At disk-to-disk speed, the HSTC™ writes in parallel, simultaneous data streams to independent virtual tape drives to complete backup within your minimum possible backup window. The Offload feature can launch offline tape archiving to easily create any number of tape copies for local and offsite storage, with absolutely no impact on your network or host operations. The virtual backup tapes will remain cached on disk for as long as you need them, ready for the fastest possible restore. Minimize Risk While Maximizing Up-Time Optimizing an innovative D2D2T disk staging strategy, Cybernetics' HSTC™ delivers the ultimate high availability recovery solution. Because the HSTC™ can automatically create redundant copies of all backup files on disk and tape, there is no longer any single point of failure in your backup and recovery process. A live copy is cached on disk, and any number of archive copies can then be transferred to tape in a serverless, offline mode. And, because each virtual tape is a completely independent data set, the HSTC™ has all the benefits of interleaving with none of the risk of multiplexed tape sets, which can be rendered useless by loss on any single tape in the set. The very high capacity of the HSTC™ disk storage makes it possible to cache days or weeks of virtual backup tapes, ready to restore at absolute maximum speed. An emergency restore of 100GB from a DLT 8000 drive will take 2.5 to 5 hours just to read the data off tape. The HSTC™ can read 100GB in less than twenty minutes.

What Can HSTC Do For You?

Restore time is absolutely crucial, so immediate access to recent backup copies is of utmost importance, and your budget won't permit a multi-drive performance tape library.	The HSTC can emulate a tape library to store backup sets for any number of days or weeks live on disk for the fastest possible backup and restore time. You can selectively choose the virtual tapes you want to archive, and Offload them to your existing tape drive with no additional cost for tapes, software, drives or libraries.
Uptime on your production servers is too critical for the cumbersome burden of the direct attached tape drives that may lock up your servers with a SCSI bus glitch.	The HSTC can attach directly to your Ethernet network, accessible via iSCSI to all compatible host systems on your network. The virtual tape drives appear just as locally attached SCSI tape drives, allowing independent, simultaneous backup of multiple servers. Your existing SCSI tape drives connect directly to the HSTC for archiving to physical tape.
You have legacy host systems that are not networked with your newer open systems, locking you into maintaining multiple backup drives.	The HSTC can connect to the SCSI tape controller on your legacy host, as well as to your Ethernet network. Your legacy host can write a local SCSI backup to one virtual tape drive at the same time that your Wintel and Lintel hosts write backups to other virtual drives via iSCSI. Your legacy SCSI tape drive connects to the HSTC and the Offload feature archives to physical tape at your convenience.
You need to add disk storage and upgrade your backup solution, but your budget won't cover both.	Most HSTC models can be configured for direct host attachment of one RAID set for storage, with a separate RAID set for the virtual tape backup functions. You can use one RAID disk subsystem to both increase the speed and capacity of your backup, and to increase your disk storage speed and capacity.
You are responsible to maintain a comprehensive, enterprise-wide backup plan, but you also have a number of users who need the ability to directly backup and restore user data files.	The HSTC can be attached directly to your Ethernet network and configured with multiple virtual tape drives and tapes that are directly accessible over the network from any number of servers and workstations over the network. Users can pick a virtual tape and load it into a virtual tape drive to backup and restore at will. Other virtual tape drives and tapes are concurrently available for your centralized backup requirements.
Your disaster recovery plan requires immediate availability of backup copies as well as duplicate off-site tape copies for Fiber networked buildings spread across the corporate campus.	From any campus location, the HSTC™ can connect to the Ethernet network and backup data from all remote facilities. The HSTC™ Offload feature can then be used to archive to both a locally attached SCSI tape drive, and to an iSCSI tape drive located in a remote building.
None of your branch locations scattered across the country employ IT staff, and you are responsible to maintain secure backup copies at headquarters.	From headquarters, the HSTC™ can present multiple virtual tape drives such that data coming in from various locations over T1 can be written to virtual tape drives and tapes. The disk-based virtual tape drives can accept the slower T1 transmissions that would destroy a tape drive with excessive repositioning, and then archive to a locally attached tape drive at maximum speed.
Your DAT drives simply cannot keep up with your server backup requirements, but you have a large inventory of legacy tapes locking you into the format.	The HSTC™ can connect to the SCSI tape controller on your server, and appearing to your existing backup software exactly as your DAT tape drive, write many virtual DAT tapes onto disk at maximum speed. Your SCSI tape drive connects to the HSTC™ and the Offload feature archives the virtual DAT tapes to physical DAT tapes at your convenience.
You have a high-speed tape drive, but your legacy hosts stream data so slowly that you do not realize the speed advantage, and repositioning is wearing on your expensive new tape drive.	You can stage all of your backups to the HSTC™ via SCSI and/or iSCSI. With your high speed SCSI tape drive connected directly to the HSTC™, the Offload feature will stream the data to tape at maximum speed to minimize the time it takes to write to tape and to eliminate repositioning wear and tear on the tape drive.
