I am existing Cloudberry Backup user. My previous machine was old and was having many issues. As such a built a modern box and installed Mint Linux 19.3 (Tina). I got my license released, installed & activated my Cloudberry software. My question is, when I connect to my storage solution (BackBlaze in my case) do I need to start a new bucket, or do I select the bucket I was using on my old machine?
Well, that's your choice, if you still need the old data as it is it's better to start from scratch using a new bucket. You can also continue to upload everything to the old one. If computer's name is different now the files will be uploaded under a different sub-folder, but you can specify the old computer name while setting up your storage.
