NetBSD's Real-Time Network Backup
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."
How does this compare with Linux Network Block Device? Sounds very similar.
There are pretty mature commercial tools for this stuff, as well - Veritas' VVR replication comes to mind.
As of Windows 2003 R2, there is a capability to do a VSS type of thing over the network to a remote server.
I'm a little ashamed that I know that, but it's true.
