Hello, 

When trying to export backup files to my SFTP account on my Synology the transfer of the files fail showing this error message at the end of the backup : 

Failed to process file /home/clients/d88454af65ec9abe592c381dad01129c/sites/prod.medeco-ch.com/administrator/components/com_akeebabackup/backup/site-medeco-ch.com-20251102-141207utc-SaqLOZlyMeig_Cia.jpa Error received from the post-processing engine: Could not create SFTP directory /WebsitesBackups Post-processing interrupted -- no more files will be transferred   I have tested login, password, sftp host and port with other ftp clients without any issue. I have tried the SFTP and SFTP with CURL, no luck.    The log file is enclosed.   Do you have any idea where the problem could come from ?   Thank you.

I assume you are trying to upload to a shared folder called WebsitesBackups on your Synology NAS.

First, you need to make sure that you have created a Shared Folder on Synology called WebsitesBackups. Please note that the name of the shared folder is case-sensitive which means that websitesbackups, WebsitesBackups, and WEBSITESBACUPS are three different shared folders.

Then, make sure that the user you are trying to connect with has Read/Write access to that share. You can set that up on the Shared Folder's Permissions page on Synology DSM's interface (Control Panel, Shared Folders, click on the shared folder, Edit, click on the Permissions tab, check the box in the Read/Write column for the user you are using to log in by SFTP, click on the Save button).
