1. A method for expanding cloud volume, comprising:
in response to receiving a cloud volume expansion instruction in a cloud backup process, determining whether there is an Input/Output (TO) request of a host in a cloud volume and confirming a snapshot started during present cloud backup;
in response to there being no IO request of the host in the cloud volume, expanding a snapshot volume of the snapshot started during the present cloud backup and the cloud volume;
expanding a bitmap of the snapshot started during the present cloud backup, and setting a bitmap obtained by expanding as a first preset value;
after completion of a present cloud backup task, expanding a snapshot volume of an another snapshot that is not started in a process of the present cloud backup; and
expanding a bitmap of the another snapshot that is not started in the process of the present cloud backup, and setting a bitmap obtained by expanding as a second preset value.
