:d: Duplicacy-Web ad-hoc FAQ

[TheBestPessimist]

There will be a proper topic for web, but currently we’re just collecting the questions and this ad-hoc post should do for now.

I forgot the master password. How can I reset it?

First edit ~/.duplicacy-web/duplicacy.json to remove the encryption_data key. Then remove all storages. Then recreate storages with the same names. Backups and schedules shouldn’t be affected.

Any way to remove the administration password once set?

You can edit ~/.duplicacy-web/duplicacy.json to remove the administration_token key.

Configure number of threads in web-ui

See

Configure number of threads in web-ui

Under the Schedule section, under a schedule, there are generally one or more jobs. On the line of the backup job where you want to configure the number of threads, click on the text under the column options. By default, it is empty so it is a “-”. [image] A pop-up will appear. There, you can specify any of the arguments listed under the documentation (including “-threads” argument) for the backup command. [image] To configure the number of threads, you would type “-threads x”, where “x” is …

Will the web version import backup jobs and settings from the GUI version?

No, settings will not be imported from the GUI version.
You only need to set them up again once, as the storage is 100% compatible between all versions (web, gui and cli) and you can resume backup jobs as if nothing was changed. All you have to do is point to your existing repository, use the same repository ID, point to the same storage and you’re finished.

Fixed chunk sizes (eg. for backing up Virtual Machines)

The Web UI doesn’t support creating a fixed-size chunk storage yet. For now, you can use the CLI to create such a storage and then add it in the Web UI.

See Set up fixed chunk sizes with Web UI

Disable autoupdate of CLI engine

CLI 2.2.0 has been released (impact on the Web GUI)

If you’re a Web GUI user, next time you start/restart the Web GUI, it will automatically download this new CLI release and use it for every operation. You can disable this behavior by fixing the version in the ~/.duplicacy-web/duplicacy.json file:

{
...
"cli_version": "2.3.0",
...
}

If this key has a blank value (the default), Duplicacy will attempt to retrieve the latest version available on github.

How to access the duplicacy web-interface remotely

By default, the #web-ui is only accessible locally, i.e. on from the same computer where duplicacy_web is running (http://127.0.0.1:3875/dashboard). If you are running duplicacy on a home server or NAS, you’ll probably also want to access it from other computers in your network. But as you will notice, accessing for example <server_ip>:3875/dashboard will give you a connection refused error. To fix this, do this: (In my case, I had to create the ~/.duplicacy-web/settings.json from scratch, i.…

Could you add “How to upgrade the web-ui?” A partial answer is at Upgrade instructions for Linux, but it makes a lot of assumptions.

Edit: Here is what I came up with:

How to use patterns in the restore command

For anyone struggling with the same problem: I did find out where I installed my duplicacy-web using which duplicacy-web. (Note that duplicacy-web is what I called my binary (or rather, the link to it), so you may need to use a different term, depending on what your binary is called.) I then did wget https://acrosync.com/duplicacy-web/duplicacy_web_linux_x64_1.6.3 sudo mv duplicacy_web_linux_x64_1.6.3 /usr/bin/ sudo chmod 700 /usr/bin/duplicacy_web_linux_x64_1.6.3 sudo ln -s -f /usr/bin/dupli…
