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 version 12.5.4 is the component that writes the new compression format. Therefore:
A compressed dump made using a 12.5.4 Backup Server can be loaded only into a 12.5.3 or earlier installation using a 12.5.4 Backup Server or higher.
If you are using a 12.5.3 installation or earlier and want to use your dumps for an archive database, use a 12.5.4 version of the Backup Server to create compressed database dumps.
A 12.5.4 Backup Server understands both 12.5.4 and earlier compression
formats; therefore, you can use a 12.5.4 backup server for both
dump and loads.
