Time Machine problem

After a few weeks using Time Machine, I each time get a message that the back has to made totally new because there are problems with the current backup.

What can I do about this?

I sometimes connect wired and sometimes wireless to my network.

Hi there, welcome to the WD Community.

I’ve seen this when the backup has been corrupted for some reason, and time machine just decides to create a different backup. On network drives I’ve seen that mounting the backup image and running a check disk from disk utility tends to work.
