It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, an embodiment of the present application provides a single system upgrade method with a backup function, including:
s2: setting a backup partition in the single system;
s4: storing the mirror image content of the partition to be upgraded to the backup partition;
s6: erasing the partition to be upgraded;
s8: and upgrading the subarea to be upgraded.
Assuming that there are 5 partitions in the system, a backup partition (e.g., partition x) is set in the system as the 6 th partition, and the size of the space of partition x is not smaller than the size of the largest space partition among partitions 1-5. The purpose of this is to allow partition x to back up any of partitions 1-5. The mirrored content of the partition to be upgraded (e.g., partition 3) is then stored into partition x. Partition 3 is then erased and partition 3 is finally upgraded.
In an embodiment of the present application, the single system upgrading method with backup function further includes:
s0: after the single system is powered on, the boot region checks the integrity of all the partitions of the single system and restores the incomplete partitions.
In an embodiment of the present application, recovering an incomplete partition is: copy a copy from the backup partition into the incomplete partition and then reboot again.
Referring to fig. 2, in an embodiment of the present application, storing the mirror image content of the partition to be upgraded to the backup partition includes:
s41: extracting corresponding information of the subarea to be upgraded from the upgrading packet;
s42: and writing the mirror image content of the partition to be upgraded in the upgrade package into the backup partition according to the corresponding information.
In an embodiment of the present application, upgrading the partition to be upgraded includes: and writing the mirror image content of the partition to be upgraded in the upgrade package into the partition to be upgraded.

the storage module is used for storing the mirror image content of the partition to be upgraded to the backup partition;
the erasing module is used for erasing the partition to be upgraded;
and the upgrading module is used for upgrading the partition to be upgraded.
The invention is realized by adopting a form of time-to-space conversion, firstly, the structural form of the system partition is seen, and on the basis of a common single system, a backup partition is additionally added for temporarily backing up the partition, and the size of the space of the backup partition is consistent with the maximum partition in a system partition x (x is 1 to n), so that the backup function is met and the occupation of the storage space is reduced as much as possible.
In summary, before the corresponding partition is upgraded, the upgrade content is written into the backup partition, and then the actual corresponding partition is updated, so that in the upgrade process, if an unexpected interrupt occurs, the reboot boot partition uboot completes the recovery processing action. The time spent in the whole upgrading process is doubled compared with the time spent in the original single system, and the time is used for replacing the space.
Referring to fig. 3, the present application further provides a computer device including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method of any one of the above methods when executing the computer program.
