Backup: 1.4.4
Extra Markdown editor settings: 1.11.0
What issue do you have?
I keep entering for the Backup Plugin Path something like \192.168.20.15\Joplin\Backup but it when I try and run the create backup, I get the path does not exist!
It does exit because I can browse right to it from within Joplin.
If I use the drive mapping letter, U:\Joplin\Backup it works. I prefer not to use drive mappings, but rather the IP address U is mapped to on my PC.
Just to be clear, are you starting your path with double \\ backslashes? This is required for UNC paths, i.e. it cannot be a single \ backslash. This means that in your case, the path should be \\192.168.20.15\Joplin\Backup.
Please note that I haven't actually tested these paths with the Backup plugin, and even if correct, they may very well still not be supported .
