Disclosed are systems, computer-readable mediums, and methods for incremental block level backup. An initial backup of a volume is created at a backup server, where creating the initial backup includes retrieving an original metadata file from a metadata server, and retrieving a copy of all data of the volume based on the original metadata file. A first incremental backup of the volume is then created at the backup server, where creating the first incremental backup includes retrieving a first metadata file, where the first metadata file was created separately from the original metadata file. A block identifier of the first metadata file is compared to a corresponding block identifier of the original metadata file to determine a difference between the first and original block identifiers, and a copy of a changed data block of the volume is retrieved based on the comparison of the first and original block identifiers.
