Feature Details

Bare Metal Disaster Recovery. Enables a one-step restoration of a complete system (operating system, applications, user data, system state) directly from backup media.

Microsoft Exchange Agent. Enables "hot backup" of Microsoft Exchange while online. Performs full and incremental backups and offers granularity of selection to individual storage groups and information stores. Automatically purges log files following backup. Supports Microsoft Exchange 2000 and higher for backup and restore.

Microsoft SQL Server Agent. Enables "hot backup" of Microsoft SQL Server while online. Performs full and incremental backups and offers granularity of selection to individual databases. Automatically truncates transaction logs following backup. Supports Microsoft SQL Server 7 and higher for backup and restore.

Disk to Disk to Any (D2D2NE). Integrated virtual archive architecture abstracts archive data from the physical media. Facilitates easy staging of backups across tiered backup hierarchies over the network. Least Recently Used (LRU) policies can automatically move lower priority data to the next storage tier (e.g., from disk to optical media or tape.) Replication policies can automatically maintain redundant archives to offsite locations to disaster recovery. Secure erase technologies ensure that data moved to next storage tier can be completely eliminated.
