Question: Time Machine says not enough space on NEW drive?
I have always used time machine to back up my iMac (3TB) to an external (3TB) drive. The external ran out of enough space to continue backups so I got a new 4TB drive. I followed the instructions to move the backup folder off the old backup drive and on to the new one. Then I pointed Time Machine to the new drive. It wont back up claiming there is not enough space...what could I have done wrong? Is it creating a complete new backup on top of the old backup I manually copied over?
iMac, OS X Yosemite (10.10.5)
