Hi there,

SFTP configuration backup fails if there is an @ in the username, Is this configuration not supported?

execute backup config sftp <file name> <SFTP server> <username@domain.com> <password>

Suggest you open a TAC case sounds like this is something that will need to be fixed in FortiOS.

I'm not sure how you can have an @ in a username. How do you SSH to this server? Use the same user syntax as you would when using SSH. SSH is usually "ssh user@hostname". Hostname is what you put in the <SFTP server> field.

Would you check that if an @ in the username is supported? Unfortunately, I do not have SSH access to the server because it is an cloud file service that offers SFTP access.

See print screen below:

FileZilla can connect without problems, see log:

DOes logging in work if you omit the domain from the user?

I cannot log in with a different username on that particular cloud storage. However, I did test a Synology NAS where I can log in with just a username and it does work properly.

So what happens when you try to connect with FileZilla using just rinobroer (without the @stack.rinobroer.nlas) as the username?

That obviously doesn't work

Status: Connecting to stack.rinobroer.nl...
Response: fzSftp started, protocol_version=11
Command: open "rinobroer@stack.rinobroer.nl" 22
Status: Using username "rinobroer".
Command: Pass: ***************************
Status: Access denied
Error: Authentication failed.
Error: Critical error: Could not connect to server

Well then. To be honest this is the first time I've seen a domain as part of a user login to SSH.

Can you escape the @ symbol with a \ to make it work?

execute backup config sftp <file name> <SFTP server> username\@domain.com <password>
