Follow these instructions to back up and restore the Redis database (and your user
data up to the point-in-time of the backup operation). Note that the backup and restore
operations should be used for the following scenarios:
- If you need to change the Redis database port number
(<db_port> in aspera.conf), back up the Redis database, change the port number, then
restore the database.
- Basic backup and restore (after a data-loss event).
