Backup drive not detected

I am getting a pop up that says my computer has not been backed up by Seagate Backup Plus Drive for 27 days...

Any messages from Seagate can be ignored as you should be using Time Machine to manage your backup. That being said, eventually we would want to remove the Seagate software. It’s not hurting anything now other than just bothersome. Most drive manufacturers have their own versions of backup software, none of which would I ever rely. Time Machine is what I highly recommend.

You may also be describing a very common issue where you've associated two different external hard drives to Time Machine but are only currently leaving one connected. To see if this is the case, open system preferences, then time machine, then choose "Select Backup Disk".



If you see two drives that are colored an olive green, then you'll want to select the older drive you are no longer using and choose "remove disk". That should take care of the problem. This has been a mistake on Apple's part that when a computer backs up to two different drives, if the drives have not been swapped out in over thirty days, instead of seeing a message that states "we haven't seen the OTHER drive in more than thirty days" it instead says "you haven't backed up in thirty days" which is extremely misleading.
