I have an external drive that I use to backup my iMac and Macbook to. There is a single folder on that drive called backups.backupdb. Inside that folder is a folder for my iMac and a folder for my Macbook. I think I did something on the MacBook computer where now it doesn't want to resume putting new incremental backups into the folder it has been using for a long time. The MacBook now wants to create a whole new monster backup and put it on the root of the drive.
Is there anything I can do to fix this problem? If I can avoid it, I don't want to have to delete everything in favor of doing a new monster backup of everything.
