Abstract: Disclosed are systems, computer-readable mediums, and methods for efficiency sets in a distributed system. A first efficiency set is determined for a first volume of data. Determining the first efficiency set includes selecting block identifiers for data blocks of the first volume, where each block identifier is used to access a particular data block corresponding to the first volume. Determining the first efficiency set further includes applying a mask to the selected block identifiers to mask at least one bit of each selected block identifier. The first efficiency set is compared to a second efficiency set for a second data store, and based on the comparison, an amount of unique data blocks of the first volume is approximated.

Abstract: 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.
