Is there a recommendation for my use case? As ransomware is able to spread over network shares since the account information is stored in windows for those shares, it's not safe to back up into a smb share. So I figured sftp is a nice solution for that
if you have uploaded them via ssh yes, as they are stored by user root.
But you could use the ftp server in the firmware, it supports ftps and sftp protocols. By doing that all your problems are solved I guess
What does executable flag mean?
It means the file can be executed (run as program), iof course it must be have executable content, like shell scripts or c compiled programs
