How to upgrade cli version

[brawlins]

I’m running duplicacy cli v.2.7.2 in a Docker container to do nightly backups and prunes using a cron job. I have fallen far behind since I set this up and would like to upgrade to the current version (v.3.2.3). However, before I do that, I want to be sure I won’t mess up my backups by upgrading.

I searched the wiki, Github issues, and the forum and couldn’t find any instructions on upgrading your version, except this one comment:

How to upgrade to a new version

I wasn’t aware that updating the gui is so complicated. With the CLI, I just copy the new exe file over the old one. Done. I suppose with the bew GUI things will also become easier? But probably never as easy as with CLI because you’ll always have some service running that needs to be stopped…

Apparently, per that comment, you can just install the new binary.

I have not tested doing backups with the newer version yet, because I don’t want to mess anything up. I have tested restoring files by initializing a repo on my computer. I was able to successfully restore files from my storage using v.3.2.3, although it did give this notice:

snapshot {repository-id} at revision 236 is encoded in an old version format

Can I just update the cli version in my Docker container and I’m ready to go? For example, in my Dockerfile I have this line, which I could just update to the new version:

RUN wget https://github.com/gilbertchen/duplicacy/releases/download/v2.7.2/duplicacy_linux_x64_2.7.2 -O /usr/bin/duplicacy && chmod +x /usr/bin/duplicacy

Once I upgrade, can I just start adding incremental backups using the new version? Is it problematic that I will have older backups that were created with the older version?

Thanks in advance for any guidance!

The web GUI finds the CLI from the directory ~/.duplicacy-web/bin. In a docker container the corresponding directory is /config/bin. So if you go into the docker console and manually download CLI 3.2.3 there, it should be automatically picked up by the web GUI after a restart.

Thanks for the quick reply! I’ll give that a try as soon as I can. I upgraded my openmediavault and something went wrong, so I’ve gotta get that running before I can bring my docker containers back up.

It worked! Thank you very much! I just updated my Dockerfile to download the newer version.
