How to install Duplicati on Synology / DSM

#23

Hi @bundito, welcome to the forum! Sorry to hear about your data loss. :frowning:

If you are asking about running Duplicati in a Docker container then yes, that’s doable (at least it with for me). I use it to back up my unRAID NAS files to an off-site location.

If you’re wanting to run Duplicati on your Synology box you may find using their package easier to with with than a Docker container.

Of course, there’s no reason you can’t try out both and see which to prefer - just don’t try to share the same destination folder. :slight_smile:

Installed Duplicati followed by Mono, and did not work.

Tried the other way around too (Removed Duplicati, and installed it again - where Mono was present and running on the system). Restarted the system to give it another chance, but same results.

Details:
DS414 with DSM 6.2.1-23824 Update 4
Mono 4.6.2-0096 (Beta-version from the official Synology-store)
duplicati-2.0.4.5_beta_2018-11-28.spk

Have you tried the workaround I posted in this thread?

Just to flesh this out a bit, does anybody know Synology paths to the Duplicati folders (like for doing a downgrade) or do DSM package not work that way?

Also, have any of you tried uninstalling Duplicati and, if so, were they any left over files needing manual cleanup?

#28

The default location for databases seems to be /root/.config/Duplicati

I ended up redirecting this (by using a symlink) to my 16TB NAS disk volume, as root is only 2.3GB on my NAS.

Thanks!

I could have sworn there was a server parameter to let you specify the “home” folder (as an alternative to a symlink), but I can’t seem to find it now.

#30

On regular Linux there is - you can just modify /etc/default/duplicati. But Synology doesn’t seem to have that equivalent. Symlink seems to work OK for me.

#31

Did you follow the step 3) in the install guide above? The message you see is exactly the symptom if you did not add your user to http group.

Hey, I also have problems with Duplicati on my DS216j running DSM 6.2.1-23824 Update 4.
I use Mono 4.6.2-0096 and Duplicati 2.0.4.5. And my user is member of http group. So looking at the Threads I found so far here, I should not get the “Connection lost” error. Any idea?

#33

My solution was to have a docker instance with Duplicati, I’m running it with OpenVPN without any problems, you can check my post here : https://community.synology.com/forum/9/post/119463
I didn’t check the “path with spaces” problem.

Hi @kliclick, welcome to the forum!

Thanks for sharing your method of running Duplicati on your NAS. Do you find / feel using A Docker container is any better or worse than a native spk?

#35

I used a Docker container because I couldn’t install a working spk in my Synology (DS1511+). But it took some time for a simple user like me to have all the settings working with the Docker container. A working native spk for me will be much easier to set up. I don’t know how to upgrade the Duplicati version in Docker (never looked for how-to’s in the internet), I don’t know if it’s better in terms of memory usage or other performance specs, etc. I tried the spk first, and I think it’s the easiest way. My answer (I repeat, as “normal” user) is that spk would be better.
