What should I do when some incremental VM backup files are lost?

If an incremental backup file before a point in time is deleted or lost, you will be unable to restore the VM to that time point.

Is it normal that CVM merges multi-level images of a VM after that VM is imported or restored?

Yes, it is normal that CVM merges multi-level images of a VM after that VM is imported or restored.

How do I handle the volumes that have a suffix of _base_0 or _base_1 in the storage pool if no users are using them?

After the file merge, CVM removes the VM from the user lists of the image files linked to the VM (image file with a suffix of _base_0 or _base_1 for example).

If the user list of an image file is empty, no VMs are using that file. You can delete that image file to free up storage space.
