If you're in charge of one or more systems that are installed at a distant location, backing them up individually can be a large chore. Fortunately, there are a number of packages that can help. Most backup packages, even those intended to create a backup of a single machine, have options to send the data to a remote location for actual storage. Ofcourse, any of the packages with this capability can be used on multiple machines. However, there are two popular packages that not only provide backup services to multiple hosts from a central location, but provide for management of backup cycles and automated runs as well. They are Amanda and Bacula. Of course, other such packages exist, and there are some excellent third-party backup solutions as well. However, both Amanda and Bacula are provided as part of Debian, so they are free as well as able to handle many systems and a variety of backup media.
