Has anyone every tried using backuppc with gluster?
I have setup a quick glusterfs on some test rigs and find it to be a very
very interesting filesystem.
gluster does run under fuse but performs like a native filesystem. I get
11.7MB/s on a 100Mb line, which is just as fast as iscsi. I can even play
an avi file that has not been completely copied! no lock manager is
required because gluster does it all. It can be setup on ubuntu in less
than 10 minutes!
gluster has a couple plugins that are very interesting. there is an AFD
mode which uses any number of gluster servers and duplicates each file on
both servers but only displays a single filesystem to clients. a server can
also be a client so it can export a local disk in duplication mode and then
mount that up and see the AFD volume. This is how I would think backuppc
would work. then a remote backuppc server would be the other node in the
cluster, keeping a duplicate copy of the filesystem available. you can also
write directly to the exported directory without using the gluster layer! so
you can skip any IO slowdown from fuse on the primary box! gluster will keep
them synced up! and gluster can run over compressed ssh tunnels!
gluster also uses any linux filesystem so is not it's own beast like GFS or
lustre or OCFS. in fact, gluster works on Mac, BSD, Solaris and Linux, and
will work on windows as soon as winfuse is stable using the native
filesystem!.
any interest? I will put together a backuppc server with a gluster data
directory and a remote mirror to test this out!
