How to remove my local Backupdb.backupsdb? On my local harddrive on my MBP retina (2014, 10.11.3) there is a Backupdb.backupsdb folder:

drwxr-xr-x+  5 root  wheel   170B  2 Jan 03:32 Backups.backupdb/

I thought that folder only exists on timemachines?
However, i want to remove it, as it only holds an old unfinished backup: 

drwxr-xr-x@ 5 root  wheel   170B 20 Mär 14:06 2016-01-02-020746.inProgress/

I disabled SIP, but neither rm -rf nor sudo rm -rf worked, not even in recovery mode. I always got Operation not permitted.

Does anyone know how to delete it?
What you are asking is to disable local backups, right? To do that, type this in terminal:

sudo tmutil disablelocal


The local backups will go away, and so will the space taken up by them (The folder, backups.backupdb)
