If you are doing a database backup, changing the number of forests shouldn't change anything.
The size of a backup is the size of the database itself; our storage format is already very compressed, so no additional compression can be done as part of the backup. The one difference is that we don't backup up the journal files themselves, so there is a little bit of space saving there. You don't mention whether you're doing a one off backup, or a scheduled backup. For a scheduled backup, you configure the number of backups you want to retain, and need space for N+1 backups because we won't remove the oldest one until the current one completes. Wayne.
