dbackup is a disk-based client-server backup system for Linux or other UNIX systems.

It works on the principal that disks are cheaper and more reliable than tapes.

Backups are started by cron probably on a daily basis by the client. The client backs up individual filesystems / directories with tar and sends the result to the server, which stores them in a simple tree-based directory structure.

Restores are trivial, either by using the supplied restore client, or by simply copying the appropriate tar files off the server and uncompressing them.

• Backup very large filesystems as long as you have the disk space
• Works with very large numbers of servers / filesystems
• No state is kept on the client, it’s all on the server
• Backup to multiple backup servers in round-robin
• Configuration can be global or per-server
• Authentication for client restores (optional)
• Supports optional gzip or bzip2 compression
• Supports client-side gpg encryption
• Trivial procedure for restores
• Daily / Full incremental backups
