    Description

      binary database dumps are comparatively small, because they don’t include index content or pre-allocated free space, and record padding. However, it’s impossible to capture a copy of a running system that reflects a single moment in time using a binary dump.

      Point-in-time snapshots are possible using mongodump --oplog (since 1.7.4) if the instance is running as part of a replica set.

      Both methodologies have advantages and disadvantages

      Even if my assertion above is shown to be incorrect, only a single disadvantage is listed for each strategy.
