我需要解决方案
From my limited perspective, I cannot see why we cannot have two backup images, one named CLIENTA_123456789 and another named CLIENTB_123456789, i.e. two backups start at the same time, i.e. both have the same trailing 'ctime' component.
In fact, it must be possible to import an image from another environment with a different clientname, but the same ctime.
So, is there a fundamental reason why two backup jobs for different clients cannot start at the same time?
