Hello. Sorry for my English, I use google-translate.
Maybe someone already has experience and uses script / program to create a backup SD card entirely in the form of an image on an external storage (HDD, USB-flash), or over the network?
I am at the moment once a week turn off the system (I have a banana pi), remove the SD card and make a copy of the system image (using imagewriter.exe).
I want to automate the process, and without removing the SD card from the board. It's real?
