Not to be confused with duplicity, or duplicacy backup programs which have similar features.

Duplicacy has been incredibly stable for me over the years and I still prefer it's lock-free deduplication design. Looks like 28 days ago there was a major release as well. Time to upgrade. :)

Another happy long-term Duplicacy user here. My only problem with it is; on the rare occasions I need to restore something from backup, I can never remember the correct syntax and always have to look it up again.

Make a script!

Or a do-nothing script if you don't want to automate it right away.

Never seen that concept before. I've done similar in the past using aliases in my ~/.zshrc

  alias taskname='echo "blah. blah... instructions for task..."'

Of course, then I have to remember what nemonnic I used for 'taskname'!

I had the exact same reaction. I have little "README.md" text files scattered about to remind me how to do things and never thought to make an interactive post-it note.

Same. I ended up writing the steps in a file because I could never remember them. It's not very complicated but a bit counter-intuitive: instead of pulling everything from the remote you first have to recreate "repository" with the same parameters as the original one, and _then_ run the restore command.

Agreed, duplicacy seems to be more resilient to the inevitable errors or hiccups along the way. The only downside is that it seems to be inefficient with storage with small metadata updates which happen frequently with my use case.

Note, its not open source. Duplicati is.

It seems to be open source (source code is in github), but the license isn't free for commercial use. I'm not exactly sure what to call it...

Source-available, I guess.

Source available

Proprietary Source available

They have some major differences. Enough so that I first tried Duplicati and ran into corruption issues so frequently that I sought out an alternative and luckily found Duplicacy.

Duplicacy has been stable for years now and I gladly pay the commercial license. It seemed like Duplicacy constructs a giant DB of all the files and manages everything that way, whereas Duplicacy's approach is much simpler and is less prone to corruption. The large DB approach seems to fail when the backup set contains a large number of files that many users manage.

Duplicati?

These names are always a mess. I half the time quit comparing these tools due to not being able to keep the names straight.

That's right -- Duplicati constructs the giant house-of-cards DB). I sometimes need to run a $> ps -ax to remember which one I'm using when it comes time to change the config.
