I also tested the GUI Version which works well:
https://acrosync.com/duplicacy-web/duplicacy_web_dsm6.2_cedarview_1.5.0.spk
Unfortunately it has the same error while uploading chunks like the cli
Thanks for this. I have a DS918+ which should be faster than yours, but your results have me hesitating a bit. Most of my backed up files are on the NAS, so I’d prefer running it directly there, but I wonder if these boxes are up for the task?
Duplicacy needs quite a bit or ram, unlike HyperBackup which was designed to work on memory constrained systems (where its advantage pretty much end).
If you add at least 8GB of ram, or better yet 32 (yes, it will work on DS918+) not only duplicacy will work just fine but also you will get much more responsive diskstation by being able to cache much more random io.
Anecdotally I was using duplicacy on both918+ and 1618+ for a while with no issues. I haven’t used the packages, instead ran directly as described here Duplicacy Web on Synology Diskstation without Docker | Trinkets, Odds, and Ends and before that in docker container.

Perfect, thanks saspus – I’ve already got 8GB of ram so that’s good news. Maybe I will give it a shot still.
I have a DS920+ and the Gemini Lake worked for me… the Celeron J4125 is Gemini Lake. That said, the x64 package naming vs Gemini Lake naming is confusing because I’m pretty sure the J4125 runs x86-64.
That said, the x64 package naming vs Gemini Lake naming is confusing because I’m pretty sure the J4125 runs x86-64.
That naming comes from Synology toolchains that match SoC names, whether there is need for that or not – there could be differences in available API in DSM, so they keep separate toolchains for each architecture; for Duplicacy this is immaterial however – it can run natively, so the packaging it simply provides a convenient way to distribute it. Just like docker for duplicacy is nothing but distribution channel – it does not benefit from anything else docker provides – it’s already self-contained native executable without dependencies.
However since (I presume) synology won’ let you install package targeted to “different” architecture duplciacy has to exist in all flavors. Inside of course is the same linux x64 (or arm64) executable.
I wonder if synology tools can build one fat SPK containing all flavors of the software…
These packages should be safe for use, as the web GUI executable is the same one from the download page. As I said earlier in this thread my only concern was that there could be some bugs in the control scripts that went into the packages but such bugs should not have catastrophic consequences.
It’s working very well for me so far on my DS918+.
Haven’t yet tested restores, but I’ve migrated my backup jobs from my Macbook to my Synology without any issues. It’s already run a couple of days of schedules just fine, including adding a new large backup job.
I’ll be testing the restore functionality today, but barring any large issues there I’m going to keep using these Synology packages.
Thanks! What do you mean by control scripts?
By control scripts I meant the scripts to start/stop the web GUI and other stuff that are required to work with the Synology Package Center.

Does it matter after the initial upload? Isn’t most of the post-seeding workload more reasonable?
Good question. I hope it’s running in some magic readonly-root mode
Same here - but keeping those permissions set for that separate user is a major pain in the… neck. 
I’m just about ready to look into running under Docker just so that I can have it mount the volume as readonly and be done with it. Are the Docker problems really that bad?
Do you have a package for the v1000 format? I have a Synology 1821+ and I tried the x64 version, but it’s not compatible.
Thanks.
I’ll build a v1000 package.

Great. I was just going to inquire about V1000 package for DS1621+/DS1821+.
This model allows 32GB of RAM.
Thank you.
gchen,
When do you expect the package for V1000?
Thank you.

I added a link to the v1000 package in the first post.
Apollolake package, DSM 6.2, v1.5 package link is working well on my DS918+.
Perhaps as an alternative to the main Synology package center the packages could be added to the community repo if the main package center is taking too long:

Thank you. I will be testing on DS1621+
