Drive letter change?

Hello,

I’ve been using Kopia to backup an external hard drive for a while now, and it works well. However, I had to move the disk to a new machine. I’ve been able to connect the existing repository, but on the new machine, but I had mount it as a different drive letter, so that part of the source path is going to change. From what I read, the drive letter is part of the unique identity, so if I just create a new policy for the disk in the new location, it’s going to re-upload the entire thing? Is it possible for me attach to the existing backup, or will I have to re-do the entire backup?

I’m connecting as the same user/host, but I am starting to think that it might be better to connect as a different user/host so that it gets treated as a shared repository and de-dupe prevents the entire re-upload? Although it sounds like de-dupe might prevent that from happening anyway? Or am I better off just de-running the entire backup? If I do re-do the entire backup, should I just delete the existing repository and create a new one so I’m starting with a fresh disk(the repo is located on a 2nd disk of the same capacity to act as an encrypted mirror/backup).

I don’t care about the drive letter, it’s an extra data disk, I only care about the relative paths starting from the root directory.

Thank you!

Nope. Deduplication works on files’ content regardless of their location. What will happen is that first snapshot run will be a bit slower as kopia will suspect that those are all new files. It will have to re-scan them all but at the end only metadata (information about new paths) will be saved to repository.
