Hello,
I have been using a QNAP TS-412 NAS for years now with different Macs and since Snow Leopard, I regularly encounter the issue of corrupted Time Machine backups which have to be re-created every few weeks. Now using El Capitan, the problem still persists.
For what I know, the reason is a broken, reverse engineered AFP implementation (netatalk) used in the Linux-based NAS devices. Now I am going to reconfigure my network storage and I heard some rumours about Apple switching from AFP to SMB2 shares.
Does that apply to Time Machine as well? Should I configure SMB2 and leave out AFP when I reconfigure?
I am using El Capitan, latest version (as far as I remember, it is 10.11.1).
Regards,
Thomas
