Abstract: 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.

Abstract: The Source Volume Backup with Adaptive Finalization Apparatuses, Methods and Systems (“SVBAF”) transforms backup request inputs via SVBAF components into backup response outputs. A set of blocks to be copied from a source volume to a target volume is designated and copied while an operating system is configured to write to the source volume. Blocks of the source volume that were written to by the operating system while the operating system was configured to write to the source volume are identified. Finalization settings are analyzed to determine whether to enter a CoW mode. If the CoW mode should not be entered, the designated set of blocks is changed to include at least one of the identified blocks and a pass is repeated. Otherwise, the operating system is instructed to enter the CoW mode and bring the target volume into a state consistent with a state of the source volume.
