> Currently, we keep WAL file per table in backup site, this creates significant data duplication in case of many tables in a backup set. We have to keep all WAL files in a single place and keep track of WAL files involved per table/backup id as links (references)
> This is not only the data duplication issue, but a performance issue as well (we copy the same file over and over again for every table in a backup set).
