Zserver® Backup

Backup and Encryption

Zserver Backup is a software that allows companies to protect their non-operational data backup stores (magnetic tapes, CD/DVD, external hard drives, etc.) by automatically encrypting the backup stream during normal backup operations.

Zserver Backup is designed to work in tandem with prominent conventional backup systems, such as BrightStor ™ ARCserve ® Backup and Veritas Backup for servers.  Zserver Backup is installed on servers that directly interact with the tapes support services (Tape Engine Service). Installation on the backup agent systems is not required.

Zserver Backup installation does not change the backup systems or any of the existing data backup processes. It intercepts the data backup stream, encrypts it and sends it down to the backup device driver to be written to the device media. As the result, data is stored on the media in encrypted state and is not readable by any system that has not supplied proper encryption key during the data rollback procedure (restoring of data from backup media back to server).

Encryption is performed on the sector level by the backup system. To initiate the data backup encryption process, encryption key needs to be loaded and get associated with the backup stream. The key is stored in the system’s virtual memory and is never written to the hard disk. All these administration tasks are completed via Zserver Administrator console, which allows you to download and activate the encryption key streamer. Zserver Backup can be launched and managed locally or remotely using TCP/IP secured connection.

Zserver Backup uses adaptive multithreaded encryption, which splits data cryptography activity into several concurrent tracks where the processing is accomplished on two or more processors according to the number of actually available processors. This technology is most applicable to modern data storage systems that encrypt data before it is written to the storage media and decrypt it when the data is retrieved.

When a backup system attempts to read the encrypted tape without the encryption key, the tape will be recognized by the system as of unknown type or size.
