Currently backups are taking 17-18 hours with 4 threads. Now that we have 16 cpus defined there, lets bump that up to 8 and see if that lowers things much. If not we can look at moving to another compression, but the database is very large so lots of compression is good to save disk space. Also filter out another output of the backup job that causes cron emails. Signed-off-by: Kevin Fenzi <kevin@scrye.com>
