I run a shared server for a group of friends and we finally all have stable income in order to do offsite backups. I looked into it and I believe backblaze to be my best option(looked into rclone for running the backups but I'm open to suggestions).

​

The thing is I've got a folder from a user who just dumped everything from all his drives with the intent of organizing it on the server. I deduplicated that data with hardlinks(files with same name, size and hash to ensure no false positives) in the name of saving space but my question now is: would I be able to preserve those hardlinks in any way or would syncing that data to backblaze duplicate it again?
