Server for the BoxBackup on-line backup system.
Box Backup is an open source, completely automatic, on-line backup system.
It has the following key features:
* All backed up data is stored on the server in files on a filesystem -
no tape, archive or other special devices are required.
* The server is trusted only to make files available when they are
required - all data is encrypted and can be decoded only by the
original client. This makes it ideal for backing up over an untrusted
network (such as the Internet), or where the server is in an
uncontrolled environment.
* A backup daemon runs on systems to be backed up, and copies encrypted
data to the server when it notices changes - so backups are continuous
and up-to-date (although traditional snapshot backups are possible too).
* Only changes within files are sent to the server, just like rsync,
minimising the bandwidth used between clients and server. This makes it
particularly suitable for backing up between distant locations, or over
the Internet.
* It behaves like tape - old file versions and deleted files are available.
* Old versions of files on the server are stored as changes from the
current version, minimising the storage space required on the server.
Files are the server are also compressed to minimise their size.
* Choice of backup behaviour - it can be optimised for document or server
backup.
* It is designed to be easy and cheap to run a server. It has a portable
implementation, and optional RAID implemented in userland for reliability
without complex server setup or expensive hardware.
