When trying to initialize on a Synology NAS over sftp I am getting a error message:

./vertical -v --log init esxi65 sftp://esxbackup@

2017-10-08 07:52:27.923334 ERROR SFTP_CREATE Failed to create the directory esxbackup/snapshots: Server connection dropped:

On the SFTP Server a directory named "esxbackup/chunks" gets created before the command aborts.

I have enabled the sshClient ruleset on the ESX host.

For the SFTP Server I am using a Synology NAS RS816 with the "DSM 6.1.3-15152 Update 6" SW-version.

Thank you in advance for your support.

Can you try using another storage directory with a shorter name like sftp://esxbackup@ I remember I had this weird problem with a Synology NAS before where it would just close the connection if the directory path was too long.

(I changed your display name -- hope it is okay with you. Let me know if you want to use a different one).

Thank your for your answer. Shortening the name of the folder unfortunaltly did not help. I renamed the directory and it had the same effect. The process creates a directory named "chunks" and aborts after that.

Mounting the Synology NAS via NFS may be easier. Apparently they made many modifications to the ssh server:
