Reset the system

Resetting the system or switching to a different image will restore the system to its initial state after the instance was created. Note that if you are using a community image or a custom image, resetting the system will restore it to the image’s original state; it does not delete all data in the environment, so the system disk will still be occupied.

Resetting the system and replacing the image will erase the data on the system disk (Not sure what the system disk is? Please refer to this document). Data on data disks, cloud drives, and file storage will not be affected.
