Quite nice my Time Machine has crashed my backup drive. Was not readable anymore. Even Linux struggled to get access.
I had t reformat it. Luckily it appeared during a backup process. So no data where lost. As an additional Backup measurement I added now a cronjob with rsync to save at least the important stuff such as pictures and private data. VMs and OS can be reinstalled.
That really does not mae me feel comfortable to use time machine further mote. And if you goole it, I am not the only one having problems with TM.
