Backup error Creating Chunks directory

Here is the log when trying to backup sftp to a Nas.

Well, I changed over to a nfs datastore on the Nas instead of sftp and it worked. Not sure what the sftp issue is.

What is the model of your NAS and do you know the version of ssh server it is running? The backup failed because sftp returned an error other than SSH_FX_FAILURE when the directory to be created already exists. On all servers I tested against, the sftp always returns SSH_FX_FAILURE in this case (which we catch and ignore). Of course, "File already exists" sounds more right and could be a more recent change.

I'll fix it to handle this "File already exists" error.

Can you run the backup again with nfs and post results here? I wonder how fast the second backup can be after the initial one.


Jhhw    Feb 23 3:22PM 2017

Pretty fast after the initial backup. It is just a plain install to test backup and restore on.

The 'File already exists' error has been fixed in version 0.3.3.
