Delta partitions for backup and restore

摘要

Systems and methods of using delta partitions for backup and restore are disclosed. An example method may include after a full backup, separating change information from static information. The method may also include concentrating the change information in a delta partition prior to a differential backup. The method may also include incrementally backing up only the delta partition during the differential backup.

1. A method, the method stored as instructions on a non-transitory computer-readable medium executable by a processor comprising:
after a full backup of stored information, separating change information of the stored information from static information of the stored information; concentrating the change information in a delta partition prior to a differential backup; and incrementally backing up only the delta partition during the differential backup, wherein the stored information is in a B-tree, and the delta partition is a dedicated partition for maintaining change information in the B-tree.
