Is BitLocker disk encryption compatible with online/offline backups?

I’m planning to set up a new desktop workstation using Windows BitLocker disk encryption. I’m wondering how the file backup works if my computer gets stolen.

That is if my disk is encrypted and then backed up to a cloud, can I read these backed up files on a new computer (in case my old one gets stolen) or are these backed up files then lost because I don’t have the original disks they were encrypted on?

Or do I just need another computer with BitLocker and the original password I used to encrypt the first disk to read these backed up files?

Thanks.
