Amanda is the most popular open source backup and recovery software in the world. Amanda protects more than a million servers and desktops running various versions of Linux, UNIX, BSD, Mac OS-X and Microsoft Windows operating systems worldwide.
Key Reasons for Wide Adoption of Amanda
- Amanda simplifies the life of a System Administrator who can easily set up a single server to back up multiple networked clients to a tape- or disk-based storage system.
- Amanda is well documented and can be set up very rapidly.
- Amanda provides the unique capability of writing backups to tape and disk simultaneously. The very same data could be available on-line for quick restores from a disk and off-site for disaster recovery and long-term retention.
- Since Amanda does not use proprietary device drivers, any device supported by an operating system works well with Amanda. The System Administrator does not have to worry about breaking support for a device when upgrading Amanda.
- Amanda uses native dump and/or GNU tar utilities. Since there are no proprietary formats, in case of emergency, data could be recovered with native utilities, regardless of whether or not Amanda is still installed.
- Amanda is very secure. Encryption on the client ensures security of data in transit and encryption on the backup server ensures security of data at rest, e.g. on a tape or on a Cloud. Amanda supports up to 4096-bit keys with public-key cryptography as well as 256-bit AES encryption.
- A unique scheduler optimizes backup level for different clients in such a way that total backup time is about the same for every backup run. Amanda frees the System Administrators from having to guess the rate of data change in their environments.
- Amanda is stable and robust because of high quality code
- The Open Source Amanda project has a large and productive Community that grows every day.
