Thank you so much! It really helps. My data is on a Synology NAS. It seems B2 buckets support is built into the Hyper Backup Synology software (the one whose purpose it to perform backups), I'm not sure if I am going to chose that or Rclone. But I already found some resources (https://www.reddit.com/r/synology/comments/hsy29y/hyper_back...), I'll investigate that. Do you, by chance, also perform your backups from a Synology NAS?
