Sharepoint 2013 Backup and external Tools

Our Customer currently deploys a new Sharepoint 2013 Farm and wants to Backup the SQL-Contents with DP but also would like to do a Full DR Farm Backup to a CIFS Share.

Right now they want to use a Script that uses Powershell-Commandlets for Sharepoint but we found out that this tampers with the TransactionLog-Sequences and therefore makes the DP-Backup unrecoverable.

 

Is there a possibility to do such a Farm Backup with DP now? The previous Integration excluded many Parts (Search-Index, Blob-Store, etc) from Backup and was not really stable.
