Abstract
Differential restore using block-based backups is disclosed. Block restore information identifying blocks in a volume that have changed since a backup time may be determined. The block restore information may be based at least in part on stored block change information indicating monitored changes to blocks in the volume. The block restore information may be provided to a backup storage node. The block restore information is used to retrieve backup data associated with the identified blocks. The backup data may be used to restore the volume to a state at the backup time by replacing the identified blocks with corresponding backup data.
