Please ensure Backup version is fully updated using live updated if you are on BE 2010 version ensure you are on latest build as BE 2010 R3 and not BE 2010 or R2. Also please note you can upgrade from BE 2010 to BE 2010 r3 using live update you would have to download latest build BE 2010 r3 from link below and then install on top of current BE 2010 verison to upgrade which will keep all your configuration same and also would use the same licesnes. lastly once you ensure BE is fully patched up please ensure remote agent version on Sharepoint and SQL server matches to remote agent version on Media sever
Additionally ensure account has right permission to backup sharepoint
