Thanks to all the developers and the Forumexperts!
This is my second time trying to use duplicati.
I create a local backup using Duplicati - 22.214.171.124_beta_2019-07-14
I back up to local folder or drive:
using --alternate-destination-marker and --alternate-target-paths but I get the title error in my log when I try to use these options.
Also the advanced options apparently completely disappear when going back in and wanting to edit them later.
The only trace I see is the added “?altern” at the end of the path.
My alternate-destination-marker seems completely lost.
The post by grossepointblank
is unrelated as this person apparently was trying to mark an alternate source; but I am trying to mark a alternate target.
Under command line I find the Target URL:
Perhaps this string has a problem?
However, %3A is the “:” and 5C is the backslash “”
To me that looks as intended.
Perhaps the duplicate appearance of “?altern” could be the root cause? But, I did not put this there, I just used the dropdown options seen in the image.
while editing the Configuration in the web page If I put the full path with the two advanced options as
and then click [Test Connection]
I get: “Success
I clicked 4 times [Next] then [Save]
We will see if the warnings disappear and the backup still works if the drive letter changes.
I’m not sure it’s the same, but this reminds of of ?auth-u automatically added to destination path where extraneous characters were added, and you have roughly the right number of them, and then they end. The suspect code is shown, but I forget if an issue was filed. Feel free if you have steps to reproduce it.
I went to Home => configuration edit=> [next] => Browse =>Manually type path
Then I removed the extra characters to obtain “T:\Duplicati_10_2019”
Test connection is success with or without the last “” I left it in
=> 3 ea. [Next] [Save]
Close all browser windows.
Home => configuration=> Export=> to File
Results in a JSON file that does not contain “altern”
If I then
Home => Run now
I will observe the two log locations:
Home =Reporting => show log
About => Show log
If the warnings and errors are still there.
Then I will try once more using the alternate drive letter and alternate markings.
With and without the apparent extra letters.
This seems to work beautifully in the latest BETA version (Duplicati - 126.96.36.199_beta_2021-06-17) and the options are very well explained in the user interface.
