1. A deduplication storage system comprising:
a processor;
a memory; and
a machine-readable storage medium storing instructions, the instructions executable by the processor to:
receive a plurality of data streams to be stored in persistent storage of the deduplication storage system;
identify a set of journals in a first journal group that are modified during a first backup process;
determine a count of the journals that are modified during the first backup process; and
migrate at least one journal of the set of journals to a second journal group based at least on a comparison of the determined count to a migration threshold.
