Box Backup
►http://boxbackup.org/trac/wiki
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.
Je l’utilise depuis des mois et j’en suis très content : backups sur un serveur externe en continu et chiffrés. Seule la création des comptes est un peu laborieuse.
