DeDuplication across paths?

I need to backup a few separate paths that contain hardlinks. Each of these paths are a separate kopia job, but on the same repository. The hardlinks in these paths may point to different kopia backup jobs.

I’m therefore relying on deduplication to ensure I don’t backup the same file across hardlinks.

Does deduplication work across different snapshot paths and jobs?

Yes. Deduplication works across all repository. Does not matter how many path/jobs you have.

You can even test it yourself to feel confident that it is true. Create local copy of already backed up path and backup it again as a new path/job. You will see that it will be very fast due to no need to transfer any data but some metadata and snapshot info.
