Configuration backup

Could you say something about how similar or different the configs are?

Who is going to maintain configs, run the backups, and do file restores?

There was a mention later of CLI? Which parts are CLI, and which GUI?

I don’t see that option for duplicati-server-util. Maybe you could ask for it.
The old duplicati-client that no longer ran after Duplicati 2.0 could delete.

You delete it, but delete the destination files at the same time for a fresh start.
The local database describes what the database contains. It’s not job configs.

I suppose I can ask for all the reset questions: Reset to what, some constant?

Reset of local database doesn’t make much sense, but delete is even in GUI.
Before first backup, local database doesn’t exist, so delete isn’t needed either.

Securing the database or unsecuring, but why is that preferable to securing?

Backup encryption has a similar question, but that setting is in the job config.

  import <file> <passphrase>      Import a backup configuration
  export <backups>                Export a backup configuration

from the ServerUtil help may be another way to do minor changes to settings.
You could even start by setting the main part in GUI then tweaking job export.

Import command creates duplicate job instead of updating existing job with same name is a forum question that the dev hasn’t replied to. And delete is missing.

Wiping out all job configurations can be done by deleting the server database.
You could then import whatever the standard (or custom) config is, for a reset.

There is also a mechanism to add or override parts of configs. This might help:

Preload settings

If you decide to backup using CommandLine, there’s no server database used.
It’s just CLI options (or a parameters-file full of them) so it’s only text to edit.

The Duplicati devs are also adding remote management of agents in enterprise
which is part of the new optional paid services. I’m also seeing a claim on page:

DUPLICATI FOR ENTERPRISE

Get the flexibility and security of Duplicati’s Open Source backup, with the tools you need to deploy at scale.

I’m not sure if this is a fit for your mass configuration scenario, but I’ll mention it.
