    Description

      RE: https://docs.mms.mongodb.com/faq/#does-the-backup-agent-modify-my-database

      The Backup Agent writes a small token into the oplog of the source database every hour

      However, per: https://docs.mms.mongodb.com/tutorial/enable-backup-for-sharded-cluster/#checkpoints
      This page correctly points out that the interval is configurable, and the token is actually inserted on this interval. Every 60 mins appears to be the minimum interval (even if you don't keep hourly snapshots) in order to ensure the oplog remains fresh.

      The FAQ should probably be updated to reflect this.
