My cloud Timemachine backup name keeps changing

HI My TimeMchine backup keeps changing and adding a number to the end of it.

Was - MyCloud-US8***-1, then went to -2 so had re start Time Machine backup as this. Just looked now and unable to back up as disk not available. Has now changed to -3.

Any ideas?

Thanks
