compression

We recently upgraded from SQL Server 2008R2 to SQL Server 2012 Enterprise. After doing this I noticed that our DB backups were barely compressing at all. Our 22gb DB was compressing down to about 4gb before upgrading to 2012 and after the upgrade our 22gb DB is only compressing down to 19gb. I've checked and double checked the compression setting on the server and all of my backup jobs and compression is turned on. Any ideas on what may be going on?
