Backup problems from Time Machine

i just noticed I have 79GB of back on my rMPB but I use a Time Capsule for my Time Machine. did you figure out how to remove?

 

Have you searched for a folder called "Backups.backupdb" yet?

When a drive is not used entirely for TimeMachine it puts the backups into a folder and on my external drive that is what it is called.

Take care,

 

When your backup drive is not available, OS X stores the backup temporarily on your internal drive. It then transfers the backup the next time you plug-in your backup drive. The space is freed up if the system disk needs it for anything else.
You can disable this, if you want to, as shown here:

Though I would suggest that if you're looking for ways to save space on your startup drive, 6Gb of temporary backup is not the biggest culprit.

I hope that you do have some backup strategy in place, if not Time Machine. Files without any backup are waiting to be lost.
