I am using the 5N for Time Machine backups and have encountered this problem three times now. I did see other threads discussing this issue but only why this happens. For those unfamiliar, a dialogue box pops up and tells you your Time Machine verification has been completed and you must erase and start over and that no further backups will be made until this is done. This is completely unacceptable. In my research in the Mac forums, it has popped up rarely since 2012 and only once in 2016 with no repairs offered. It seems to be a NAS issue and Drobo is the NAS drive.
I am looking for help on how to fix it and/or stop it and hoping someone here can offer some assistance, please.
Setup: Mac Pro 2013
Drobo 5N bought 2016
OS El Capitan 10.11.6
*fairly experienced and knowledgeable of Mac maintenance
Thank you for your time!
