I have a backup to a backblaze B2 bucket used just for duplicati. While duplicati reports the size as “Backup: 257.88 GB” on backblaze the size is reported as “Current Size: 277.1 GB”.
Where are the extra 20GB? Could it be that duplicati lost track of some files in B2? Is there a way to clean up the extra space used without uploading everything again?
Note that another backup I have of the same files to local disk is consistent in the reported and actual size used.
