Method and device for making differential upgrade package, and method and device for system differential upgrading

摘要

The embodiments of disclosure disclose a method for differential upgrading of a variable-partition system, which includes the following steps that: partition information is acquired from a differential upgrade package; data backup is performed to data of old partitions; partition re-division is performed on the old partitions to obtain new partitions according to the partition information, and the new partitions are formatted; the backed-up data is recovered into the new partitions; and differential upgrading is performed of the variable-partition system by virtue of the differential upgrade package. The embodiments of the disclosure also disclose a device for differential upgrading of the variable-partition system. The embodiments of the disclosure further disclose a method for making a differential upgrade package with partition information. The embodiments of the disclosure further disclose a device for making a differential upgrade package with partition information. By the embodiments of the disclosure, the problem in the related art that differential upgrading cannot be implemented when partition information of a target version and the partition information of an original version are varied is effectively solved.
