Hello,
Are you going to implement the Amazon Cloud Drive?
We donât officially support Amazon Cloud Drive, but we do have a storage backend that works with Amazon Drive.
If you want to give it a try, youâll need the CLI version to initialize the storage. First, go to https://duplicacy.com/acd_start to download a token file, and then run the CLI version with the init command to initialize the storage. The storage url should be like acd://path/to/storage. Also, remember to encrypt the storage by providing the -e option to the init command, otherwise Duplicacy will not be able to connect to that storage when you run backup or any other commands.
After you initialize the storage with the CLI version, you can switch to the GUI version and select the repository. The storage url will be automatically loaded.
Here is what happened with the Amazon Cloud Drive storage backend:
We started the development at a time when Amazon Cloud Drive was open to third-party developers. We created a a new API key (or security profile in their terminology) and whitelisted the security profile so that it can be used by Amazon Cloud Driver users after authorization. However, we made a mistake when whitelisting the security profile â the permissions werenât enough to read all files. We should have requested for clouddrive:read_all but we got `âclouddrive:read_otherâ instead, which means that plain text files are not accessible by Duplicacy. Most files stored to the storage by Duplicacy are binary files, except for the âconfigâ file when the storage is not encrypted. Therefore, our security profile works only if the encryption is enabled.
After we realized the mistake, we created a new security profile but found out that there wanât any option to whitelist the security profile. We contacted the Amazon Cloud Drive team who told us that there was no way to modify the permissions of a security profile after it has been whitelisted, and Amazon Cloud Drive had just become invitation-only so we had to request for an invitation only. After answering several questions they turned down our request. This was a surprise at first but it was understandable â Amazon Cloud Drive is targeted at personal users and Duplicacy has no way to prevent business users from using it. However, this leaves us in a strange position â on one hand we have a working security profile (if the storage is encrypted), and on the other hand they can block our security profile any time, especially considering the fact that it was acquired before their approval was needed. Therefore, we decided to not officially support Amazon Cloud Drive, but you can use it at your own risk.

Hopefully you can chip away at this⌠$60 cdn unlimited is a real steal. Unclear if thereâs a glass ceiling on this.
Resurrecting this thread.
Is the amazon drive support broken? Iâm attempting to add (encrypted) repository and get âtoo many requestsâ error:
mymac:Test me$ duplicacy -d add -copy yandex -e -bit-identical amazondrive testdrive acd://duplicacy

Question: is it supposed to be broken and not to be fixed (which would be understandable), or does it supposed to still work? I understand ACD is not supported anymore, jut would like to know if it even worth trying or it is known to be completely broken.
I suppose the status remains âunsupportedâ?
What I was trying to undersstand â is it âWorks but unsupportedâ or âBroken now, so donât even botherâ.
But I guess, unsupported also means no questions about this in the first place, so lets close the topic 
Aaaand I think I found an answer to my question: The error code returned is 429, which perhaps is due to https://forums.developer.amazon.com/questions/54132/getting-429-too-many-request-errors.html
So, nothing to be done. Itâs a pity, because Amazon Drive is one of the fastest destinations Iâve tested.
