I have set --synchronous-upload to true but I still have 4 parallel uploads.
Then I have set --asynchronous-upload-limit to 1 but still I have 4 parallel uploads.
If I set --asynchronous-concurrent-upload-limit to 1 then I get 1 upload
I think (but not really sure) that --asynchronous-upload-limit is the number of files that are created locally ADDITIONAL to the ones that are uploaded. Is that correct?
Are you not in the GUI, seeing help text? Let me copy it from Duplicati.CommandLine.exe help text:
--asynchronous-concurrent-upload-limit (Integer): The number of concurrent
uploads allowed
When performing asynchronous uploads, the maximum number of concurrent
uploads allowed. Set to zero to disable the limit.
* default value: 4
Above is somewhat new, and not yet in the manual Advanced options yet. The two below are there.
--asynchronous-upload-limit (Integer): The number of volumes to create ahead
of time
When performing asynchronous uploads, Duplicati will create volumes that
can be uploaded. To prevent Duplicati from generating too many volumes,
this option limits the number of pending uploads. Set to zero to disable
the limit
* default value: 4
--synchronous-upload (Boolean): Upload files synchronously
Duplicati will upload files while scanning the disk and producing volumes,
which usually makes the backup faster. Use this flag to turn the behavior
off, so that Duplicati will wait for each volume to complete.
* default value: false
