Data backup is challenging enough, but trying to get it done in a heterogeneous environment can be a true nightmare.
A company named Zmanda has what it calls the most complete open source backup and recovery system tailored-made for multi-vendor shops.
The Amanda Enterprise system allows admins to back up multiple Windows, Linux, Solaris and Mac OS X clients to a single backup server. The system relies on the Microsoft Volume Shadow Copy Service (VSS) to maintain reliability during hot backups, as well as the Windows System State that uses Active Directory to ensure bare-metal recovery across multiple hardware and software environments.
Backup, archiving and recovery are available for servers, workstations, desktops and most business-critical applications, with data stored on disk, tape, optical devices or online services.
The company also has a Department of Homeland Security certification stating it to be free of security defects.
