Chapter 11. Backing Up Data > Backing Up and Archiving to Tape with Amanda

11.4. Backing Up and Archiving to Tape with Amanda

Tape is still a popular backup medium. The Advanced Maryland Automated Network Disk Archiver (Amanda) is an open source package that manages tape backups. Developed at the University of Maryland, it's included in many distributions of Linux, including Debian. Amanda's features include:

  • The use of traditional Unix backup formats such tar and dump

  • Operation over a LAN, backing up client data to a central tape server

  • Support for backing up Windows clients via file shares

  • Support for standard tape devices and many tape changers, jukeboxes, and stackers

  • Ability to balance full backups over a multi-day backup cycle

  • Support for incremental backups to write daily changes

  • Data compression on either the client or the server, or via devices that include hardware compression

  • Prevention of accidental overwriting of the wrong media

  • A holding disk strategy that allows for staged or delayed writing to media

  • Authentication through Kerberos or its own authentication scheme

  • Data encryption for protection over unsafe networks
