Just five days after a complete back up using Time Machine the following message appeared:


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


Very few files were changed during the five days. I have had this message before but after several months of trouble free backups. The complete back up takes approx. four days to complete.


I have been using a NAS WD My Book World for over a year now without any trouble. I am using the latest firmware.
