Hi,
I have a QNAP TS-219 running Version 4.12 (newest). I have two Macs:
Both run Yosemite 10.10.2. Both do a Time Machine backup to QNAP which works fine, as long as only ONE machine uses the TMBackup share, no matter which one. As soon as the other did a backup, both complain with the error message, that it has to recreate the whole backup (sorry, I am not at home, so I don't see the actual message). This is very annoying and renders Time Machine useless. This used to work before. I have no clue, what the reason is.
What can be the reason?
Regards,
Darko
