Disk-to-Disk Backup

Traditional tape based backup solutions are a cost-efficient possibility for data protection. With the growing requirements concerning data availability and recovery new solutions are coming with enhanced functions.

SteelEye™LifeKeeper® Disk-to-Disk Backup for Windows systems is a complex solution that offers realt-time bakups and features for data archiving. LifeKeeper® Disk-to-Disk Backup is a part of the SteelEye product family for Data Protection, High Availability Clustering and Disaster Recovery.

Loss of data caused by corrupted tapes is eliminated by disk storage and systematic data protection on drives.

With LifeKeeper® Disk-to-Disk Backup production data are replicated immediately  and continually to a defined backup drive. In case of failure or disaster the most current version can be accessed. Data are always available on a hot-disk and can be transmitted to the server without decryption and compression.

LifeKeeper® Disk-to-Disk Backup can operate with a wide range of standard industrial backup systems. It offers possibilities for automated and continuous backup processes so daily backups on production servers are eliminated.

In the shown configuration, a backup server is built with defined seperate volumes designated for each business day.

Data replication is used to provide a real-time copy of business data onto the respective volume of the backup server. In the example 5 business days of data is available for immediate restore via simple mount and drag&drop operation at any time. Once a week, a full backup is taken to tape for offste storage.
