[BackupPC-users] gluster

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!
