Any comment on that approach? http://hackingdistributed.com/2014/01/14/back-that-nosql-up/
Snippet: HyperDex uses HyperLevelDB as its storage backend, which, in turn, constructs an LSM-tree on disk. The majority of data stored within HyperLevelDB is stored within immutable .sst files. Once written, these files are never overwritten. The backup feature within HyperDex can extract a snapshot of these files via an instantenous hard link in the filesystem. This state, once snapshotted so efficiently, can then be transferred elsewhere at will. At the cluster level, backups pause writes for a short period of time while the HyperDex daemons take their individual snaphsots. Because individual snapshots are efficient, the pause generally takes less than a second.
