Service cluster instance backup and recovery methods and related devices

A service cluster instance recovery method, performed by an electronic device, the method comprising:

• acquiring, when an instance recovery request for a service cluster instance is received, backup data of a container group in the service cluster instance;
• creating a target backup persistent volume claim and a target backup persistent volume object corresponding to the container group according to the backup data of the container group, the target backup persistent volume claim claiming storage attribute information required by the container group, and the target backup persistent volume object pointing to a storage area for the backup data of the container group;
• creating a target persistent volume claim and a target persistent volume object corresponding to the container group according to the target backup persistent volume claim and the target backup persistent volume object corresponding to the container group;
• and
• operating the container group according to the target persistent volume claim and the target persistent volume object corresponding to the container group.

A non-transitory computer-readable storage medium storing a plurality of instructions, the instructions, when being loaded by at least one processor, causing the at least one processor to perform:

• determining a service cluster instance, the service cluster instance comprising at least one container group;
• for one container group in the service cluster instance:
• setting a source persistent volume claim and a source persistent volume object corresponding to the container group, and storing the container group based on the source persistent volume object, the source persistent volume claim claiming storage attribute information required by the container group, and the source persistent volume object pointing to a data storage area of the container group;
• creating, for the container group, a backup persistent volume claim and a backup persistent volume object corresponding to the container group according to the source persistent volume claim and the source persistent volume object corresponding to the container group when the service cluster instance satisfies a backup triggering condition;
• acquiring, for the container group, target data of the container group to be backed up based on the source persistent volume object corresponding to the container group;
• and
• backing up, for the container group, the target data of the container group to a storage area pointed by the backup persistent volume object corresponding to the container group according to the backup persistent volume claim corresponding to the container group.
