[Bug]: The backup is successful but the size information returned is wrong. Sometimes it is 0 and sometimes it is an incorrect value.

Current Behavior

The backup is successful but the size information returned is wrong. Sometimes it is 0 and sometimes it is an incorrect value.

Expected Behavior

The information returned by the backup is correct

Steps To Reproduce

1. Create a backup
2. After the backup is successful, check that the backup file size does not match the actual size (there is data but the size returned is 0, there is data but the size of the data is obviously wrong)
3. However, if you re-issue the backup, there is a probability of obtaining the correct result.
