> The backup feature from OAK-1159 is currently unable to detect cases where the same binary
or some other piece of shared content is referenced from two or more places in the content
tree, and ends up duplicating such content in the backup.
> It would be nice if the backup could automatically detect such cases and avoid the extra
duplicates. See the {{testSharedContent}} test case in {{FileStoreBackupTest}}.
