Can't find 68GB local backup folder (regular backups on an external hard drive) A few days ago my local hard drive shows 68 GB of backups.

 I regularly backup with time machine on an external disk and even after running a backup these file stayed.
I tired using SupaView and DaisyDisk to look at the files but both do not have access even while using then as an admin. Therefore I don't even know where this folder is or what i contains.
I have OSX El Captain (10.11.6)

Has anyone had the same issue or know what and where this folder is?
It's likely your Local Time Machine Snapshots.

In Sierra, these are stored in /.MobileBackups/Computer, but it's not advisable to manipulate this folder directly. Either use the Time Machine application to delete individual snapshots, or disable local snapshots altogether by running the following Terminal command:

sudo tmutil disablelocal


I can't say why MacOS isn't cleaning them up after you've run an external Time Machine backup. EDIT: On my MacBook Pro, I also see some old backups that pre-date my last external backup.
