There are several questions like this but they are a bit old.
I have a pi zero running Raspbian. The pi is enclosed in a metal case (don't worry, it's vented) and I can only access the SD card by disassembling the case, which is tedious and impractical for routine backups.
I am using Mac OS and would like to backup the entire SD card over the local wifi. Of course I have found many pages on this topic, but I would like to hear from people who have been able to do this successfully. What tools and approach have you used?
Any experiences of success using recent versions of Raspbian are appreciated.
