You cannot load dumps generated with “compress::” into an archive database. There are no compatibility issues with dumps using this compression option on traditional databases.
The format of a compressed dump generated with the with compression = compression_level option has changed. Backup Server versions 15.0 ESD #2 and later is the component that writes the new compression format. Therefore:
A compressed dump made using a Backup Server version 15.0 ESD #2 and later can be loaded only into a pre-15.0 ESD #2 installation using a Backup Server version 15.0 ESD #2 or later.
If you are using a pre-15.0 ESD #2 installation and want to use your dumps for an archive database, use Backup Server version 15.0 ESD #2 or higher to create compressed database dumps.
A Backup Server version 15.0 ESD #2 and later
understands both 15.0 ESD #2 and earlier compression formats;
therefore, you can use a 15.0 ESD #2 Backup Server for
both dump and loads.
