Works on single server, running secondaries for all shards. Backup is done by simple copying with rsync. db.fsyncLock() is used to freeze servers before backup, so they continue recieving oplog and voting. Config server is backed up by mongodump.
Fails if Balancer is runniing - because it can lead to inconsistent backup.
Tested with mongo 2.6 and pymongo 2.6. Probably will work with 3.0.
Notice: this version doesn't do backup rotation.
