NetBSD's Real-Time Network Backup

Posted by ryuzaki0 on from the old-hardware-power dept.

jschauma writes "One of NetBSD's developers, der Mouse, was interviewed by DaemonNews about his real-time network backup system (originally presented at BSDCan 2005), where changes to your local filesystem are automatically propagated to a backup server. In his interview der Mouse tells about his idea, how it works, and of course, how cool it is."

    But hasn't Sun been doing this with Solaris for at least 3 years?

      OpenVMS has been doing this for even longer using volume shadowing.

    This idea is really cool, but implementing it by putting hooks into each device driver seems overly complicated.
    FreeBSD's GEOM is solving that: http://www.bsdcan.org/2004/papers/geom.pdf

    Also, there's "GEOM gate" on FreeBSD: http://garage.freebsd.pl/GEOM_Gate.pdf
    For other cool stuff with GEOM see here and here. See also this discussion thread about ggate's limits.

    I prefer Dirvish, and I highly recommend that people looking for a good harddisk-based backup system take a look at it. I've looked long and hard for a good backup system and this is the first that seems to fit the bill for me.
