: tape libraries simultaneously. Enterprises with several smaller backup applications and tape solutions can write their backup data to a single disk library that appears identical to each of their tape libraries dedicated to individual backup applications.

Disk-based solutions can back up data more than three times as fast as a tape. Additionally, disks eliminate the need for constant tape replacement and changes. Fierce competition and technological improve-ments have driven the price of hard drives down to the point where a very large hard drive has a pretty low cost. On average, a typical large hard drive will cost one-third the price per gigabyte of comparable tape media in terms of TCO.

Some of the best disk-based backups solutions provide daily automatic integrity checks, which assures that whatever has been backed up, can be restored with 100% guarantee. The data can be replicated securely from one disk based system to another system reliably.

Moreover, disk libraries will always be seen as a viable alternative for those enterprises that require high availability. Disk-based backup is the way to go!
