Backup Exec

Backup Exec is proprietary backup software currently developed by Symantec. Backup Exec has a long history of being sold from one company to another. Its earliest roots stretch back to the early 1980s when Maynard Electronics created a bundle of software drivers to help sell their tape drive products. Today, Backup Exec is a data protection solution that provides continuous disk-to-disk-to-tape backup and recovery. Continuous protection is now available for Microsoft Exchange and SQL Server in addition to file servers and workstations, eliminating daily backups and providing point-in-time recovery.
