Fellow MongoDB users!
It troubled me that there seems to be no MongoDB equivalent of 'mylvmbackup', the LVM-snapshotting backup util used with another popular database system.
So I wrote one. Early days so far: it's just a glorified shell script and needs way more error checking. But already it works for me and I figured I'd share the joy. Bug reports, patches & suggestions welcome.
