It would be very useful if the backup files were in a format usable by other tools, e.g. BSON readable by mongorestore, instead of a "custom" format like Ruby marshal data.
For the times when you really need the backup, you wan't the backup files to be as easily usable as possible, no matter what the environment.
this is a really nice idea. Still not sure when have time to add this feature. Any help is very welcome!
