I have a new MackBook Pro and all of my storage is on my home network. I have no issues accessing the drives, one being a WD MyBook live the other being a 3TB redundant server. No matter what i do, what drive i have the time machine backup on, Every once and a while(as soon as every back some times a week or two in between) i get the message "after verifying time machine needs to create another back up." then it proceeds to take 8 hours to make a new backup. I would like my backups to be on a network drive but that means access via wifi and i have been told by several that i will keep having this issue unless i use a usb drive to backup. i would like to keep backups but this is a PITA to hard connect to a non networked drive that i then have to backup to the server. Does anyone have any suggestions?
