Time Machine user - asks to recreate a backup all the time


My WDMYCloud has been working fine for about 3 months.  I now get the following message

“Time Machine completed a verification of your backups on “WDMyCloud”. To improve reliability, Time Machine must create a new backup for you”

any suggestions?  

Thanks in advance
