Creating Sharepoint 2013 backup

Hi,

 I have a strange problem here, which I cannot understand.

 I have Sharepoint 2013, 3 servers one app and two wfe. I have configured wfe1 with ConfigureSharePoint.exe -EnableSharePointProtection and ConfigureSharepoint.exe -resolvesAllSQLAliases, I have two aliases.

 The db are on two SQL servers, all but one are on SQL 2008 r2 SQL and the one is on SQL 2013 and DPM is 2012 r2.

There is no DPM backup set up  for this Sharepoint server, so I am creating a now backup. I create a Sharepoint backup using wfe1 and every thing looks normal, the backup complete normal but it only backup the DB on the SQL 2013 and nothing else, I see no errors??

Pls adv,

Erró
