@bhavikpatel7023 - Thank you for the code links. It certainly answered this part of the question:
Unfortunately, it doesn’t help me figure out how to run a backup from the command line and specify output file name and location.
The .py code reads well and offers some clues to the process, but I am not a developer. So, I am not able to figure out where to actually make changes to all those variables so they would allow me to get my desired results. Even though I found the variables in the code for specifying file name and path, I have no idea how I can influence their values.
Thank you though. It proved to be good reading and insightful to the overall process.
Still looking for an easy way (via command line) to execute an ERPNext database backup and specify the output file name and path.
