Amanda Network Backup
Open Source. Open Formats. Open APIs.
What is Amanda?
AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is
a backup solution that allows the IT administrator to set up a
single master backup server to back up multiple hosts over network
to tape drives/changers or disks or optical media.
Amanda uses native utilities and formats (e.g. dump and/or GNU
tar) and can back up a large number of servers and workstations
running multiple versions of Linux or Unix. Amanda uses
a native Windows client to back up Microsoft Windows desktops and servers.
The most recent stable release is version 3.1.2, released on
August 12, 2010. It is a bug fix release.

Release Notes for the 3.1.x release series:
- config
- The 'rawtapedev' keyword was removed, and the 'label_new_tapes' keyword was deprecated.
- New warnings for dangerous splitting configurations
- changer
- We have many changers implementing the new changer API. The new changers are faster, more reliable, and have many new features. One new features is that the changer keeps track of which label is in which slot, allowing it to locate a tape faster. But with some changers (new chg-multi or chg-robot without a barcode), it doesn't get automaticaly notified if you change the volume in a slot. In this case, you must notify the changer of it with the 'amtape update' command:
- amtape DailySet1 update 3-8
- amtape DailySet1 update 3-8=
- amtape DailySet1 update 3=DailySet003
- See amanda-changers(7) for more information.
- ndmp, dvdrw
- New Amanda devices - see amanda-devices(7) for more information.
- amsamba
- The default amandapass file for the amsamba application is $CONFIG_DIR/amandapass, but it is /etc/amandapass for program GNUTAR. Don't forget to move the file if you switch to the amsamba application.
- ampgsql, amsuntar, amraw
- New applications to back up PostgreSQL databases, Solaris systems, and raw device files, respectively.
- amtape
- Amtape's behavior has changed; see NEWS
- amrmtape
- Rewritten with new command-line interface; see NEWS
- amdevcheck
