[gentoo-server] Backup software

[Jose Gonzalez Gomez]

Hi there,

    I sent this to the gentoo-user list without much success, I hope in 
the server list there are more people doing backups... you know what 
they say: "there are only two kind of people: those doing backups and 
those that never lost any data". I hope I become one of the third kind, 
those that never lost any data but are doing backups :o)

    I'm searching for some backup software with the following requirements:

    * Capability to scale from a single machine to backups of full 
networks, including heterogeneous OS (Linux, Windows,...)
    * Capability to do full or incremental backups
    * Network friendly (don't wanna have my network down because the 
backup traffic ate all the bandwidth)
    * Possibility of using different backup media (tape, CD, DVD, HD,...)
    * Ease of maintenance and recovery, preferably with unattended
      operation (don't wanna be hanging around changing tapes)
    * Snapshot backups of live file systems (don't wanna have to stop my
      web/mail/database server to do the backup)
    * Ready to go (so please, don't tell me to use tar / cpio / mt)
    * Of course open source

    After a preliminary search, I've found Amanda, Mondo Rescue and
Bacula, all of them in portage. I would like to hear experiences, and
thoughts about this.

    Thanks in advance, best regards
    Jose
