SSH remote directory not accessible

[horkko]

Hi,

I've just discovered this great tool and tested it on a local directory. As said in the documentation, rotate-backups handles remote directory over SSH.
I've tried it creating a new configuration file as follow:

[ssh.cluster023.x.x.x:/backups]
ssh-user=example
daily=1
weekly=7
monthly=4
yearly=12

Unfortunately, the script throws an error which I don't understand:

 rotate-backups  --dry-run -y 2 -m 12 -w 8 -p -d 8  ssh.cluter023.x.x.x:/bakcups/ 2>&1

ValueError: The directory ssh.cluter023.x.x.x:/backups/ isn't accessible, most likely because it doesn't exist or because of permissions. If you're sure the directory exists you can use the --use-sudo option.

Is there something misconfigured of I did wrong??
For info, the hostname I try to connect to starts with ssh could it be the problem?

Thanks for your reply
