The User Space Incremental Tracking Apparatuses, Methods and Systems (“USIT”) transforms backup driver installation request, backup data store request inputs via USIT components into backup driver installation response, backup data store response outputs. A new most recent activity entry in a file system journal associated with a data volume is determined by a user space tracking agent. Newly changed files on the data volume are determined by processing journal entries between a previous most recent activity entry, as indicated by a last entry marker, and the new most recent activity entry. Changed data blocks associated with the newly changed files are determined. The changed data blocks are marked as changed in a tracking store. The last entry marker is updated to reflect the new most recent activity entry. Data blocks flagged as changed are sent to a backup device. The sent data blocks are marked as unchanged.
