"No previous revisions found" error

DrChapa     Mar 12 12:02PM 2018 GUI

I downloaded Duplicacy 2.1.0 beta 11. Created a new backup job (backed up to Backblaze B2 cloud). After it completed successfully, I tried to Restore it.

As soon as click the Restore button, I get a popup dialog with the caption "Duplicacy Error" and error text that says "No previous revisions found".

A different machine was also backing up to the same storage.

Did the initial backup actually finish? Do you see the snapshot file snapshots/repository_id/1 in the storage?

The second machine had not finished, but the first machine (which I was trying to restore) had finished successfully.

Yes, the repository snapshot file "1" is there and is 600 bytes in length.

Can you try to run the CLI executable to list the revision:

cd /path/to/repository
duplicacy_executable -d list

On Windows, the CLI executable can be found under either C:\Program Files (x86)\Duplicacy or C:\Users\username\AppData\Local\Duplicacy, depending on if you installed Duplicacy for all users or for the current user only.

On macOS, the CLI executable is usually under /Applications/Duplicacy.app/Contents/Resources.

Did you use the default repository id generated by the GUI? Does it contain any special characters?
