Delta partitions for backup and restore
First Claim
Patent Images
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.

Abstract
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.

8. A system, comprising instructions stored on a non-transitory computer-readable medium executable by a processor to implement:
-
a backup manager conducting a full backup and a differential backup of stored information; a separator operating on the stored information between the full backup and the differential backup to separate change information from static information; and a concentrator to store the change information in a delta partition prior to the differential backup, wherein the backup manager only backs up 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. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system including machine readable instructions stored as program code on a non-transitory computer readable medium, the machine readable instructions executable by a processor to:
-
separate change information from static information following a full backup; concentrate the change information in a delta partition prior to a differential backup; and back 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. - View Dependent Claims (17, 18)
