Question: Getting messages from macOS about creating a new backup
I am getting this error message ' to improve reliablity, Time Machine must create a new backup for you'
I am starting to think that the hard disk on the time capsule is starting to fail. I have restarted the time capsule to see if there are any errors. But it boots up and everything is fine.
I am wanting to check the drive to see if there are any bad blocks but I don't know how to do this. did a Google search and can't find anything.
question I have, what is better a external hard disk to backup or still using time capsule?
I am tempted as well to have have 2 backups in case one fails and I can rely on the other.
My time capsule also backs up my MacBook as well.
Mac mini, OS X Yosemite (10.10.1)
