Abstract

Methods and apparatuses for backing up data to a database are provided. A specified data set to be backed up is broken down into a plurality of data blocks, each data block is associated with a data block digest, and the data blocks and associated data block digests are stored in the database. When one or more data blocks are subsequently changed, an update to the backup may be performed by adding o the backup data only the data blocks that have changed since the initial backup. Methods and apparatuses for restoring backup data from a database are also provided. Timestamp information associated with the data blocks in the database is used to select the data blocks to be restored.
