Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing filtered backups of a distributed database. One of the methods includes receiving a user request to generate an incremental backup to be added to a user specified backup sequence for a distributed database, wherein the user specified backup sequence specifies a subset of one or more database tables to be included in backups in the user specified backup sequence. Dirty partitions of the one or more tables covered by the user specified backup sequence are identified, wherein a dirty partition is a table partition that was created or modified after generation of a most recent backup in the user specified backup sequence. An incremental backup to be added to the user specified backup sequence is generated, the incremental backup comprising contents of the dirty partitions of the tables covered by the user specified backup sequence.
