Copy multiple backup repositories to one, unified storage?

Hi, my current backup setup looks like this: I have multiple computers which are configured to use their own B2 bucket. Thats works quite fine.

But I want to change the setup to get the advantages of data deduplication and set the backup target to just one single B2 bucket.

Unfortunatly that does not seem to work when I try to copy all the snapshots to the new repo. The first computer was fine, but the second gives me an error:
Two storages are not compatiable for the copy operation

In both cases I added the repo with ./duplicacy add -encrypt -copy …

Is there a solution to this problem?

Best regards

Unless the original storages were created with add -copy in the first place, I don’t think there’s a way to merge them together, since they use a different set of hashes for encryption and are incompatible from then on.

What I would do is keep one of the storages and set up the other computers with this new storage and keep the old buckets around for a while until you’re sure you won’t need them.
