Use robocopy either standalone or the builtin version. I would recommend the standalone as it is much more granular.

Hi Joe,

Thank you for the response. I am not sure I understand your suggestion. Copying the actual files is where RoboCopy would be used. I have already copied the files. My problem is that if I move the cloudberry instance over to the new server I must either do a restore on that server which I do not need as the files are already there or create a new backup which would result in needlessly uploading 1.5TB (not an option). I need to know how to tell Cloudberry that the files are already uploaded. I can rename the folder in S3 to match the new server but this is just a guess. Are there some instructions for how to accomplish this task?

see if this blog post helps: https://www.cloudberrylab.com/blog/how-to-continue-backup-on-another-computer/amp/

Thank you David,

Excatly what I was looking for. I was able to resume backups using this method. Worked as expected. One note worth mentioning was that the drive letter changed. I ended up mapping the 2nd drive to a folder on the C drive in order to ensure the path remained the same.
