I set up repos on S3 and REST, works great!
I tried to set up one on a remote linux, via SFTP (the backup is actually done locally on that server) and got tis:
srv is defined in .ssh/config:
Host srv.XXX srv
HostName XXX
Port 2223
User root
IdentityFile ~/.ssh/srv.private.openssh
Is this supported by Restic Browser? If not - how should I add the ssh private key?
