Tape/Virtual Tape
21st Century’s virtual tape backup systems simulate traditional tape transports and processes—but with faster, more reliable media and connectivity. These systems store data on disks instead of tapes, while preserving an external tape interface through a seamless virtualization that is transparent to existing applications, which interact with the system as though it were a physical tape library.
You benefit from faster disk performance, without making significant changes to your existing tape-based backup methodologies. Additional advantages include:
- Shortened processing time
- Limited changes to the existing backup structure
- Improved performance when compared with physical tape
- Enhanced reliability of your backup-and-restore infrastructure
Virtual Tape Needs Backup Too
Our DR/VFI technology provides a simple method of backing up the critical tape data to remote tape pools or transportable media for off-site rotation. Original data remains on-site for production accessibility, while stacks of high-density media reduce the number of tapes stored off site. The tape copy process calls for tapes when they are not being used in production and creates a copy of this data.
Additional features include the capability of halting a tape copy in process when any production application is waiting for the volume being copied, minimizing any contention that could slow down production processing. The restart capability of the tape copy task will re-attempt the copy once data is available. This unique functionality ensures that offsite copies of critical data are always available at a recovery processing location.
