Growing tfs Tfs_DefaultCollection database

Question

Best people,
Our TFS 2013 Tfs_DefaultCollection DB is growing.
It has now the size of 149GB and still growing.
When I look at the Disk Usage by Top Tables there are two very big tables.
dbo.tbl_Content is 54GB and dbo.tbl_BuildInformation2 19GB.
We started with a fresh new environment a year ago.
We have about 65 projects.
Setup:
Database server:
OS:  Windows 2012 R2
SQL:  Microsoft SQL Server Enterprise Edition 11.0.5058
Application Server:
OS:  Windows 2012 R2
TFS:  12.0.31101.0(Tfs2013.Update4)
Best Regards Fabian Stans

Hi Robin,   
Thanks for your reply.
The above solution works to remove completed build(s) and all its related data from TFS collection database. We can execute Tfsbuild delete command to bulk delete builds by date, after executed the Tfsbuild delete command, the build information can be removed
from tbl_Build and tbl_Buildinformation2 tables immediately, but need wait that related data be removed from
tbl_ContainerItem, tbl_File 
and tbl_Content tables. Please refer to the discussions in this post:

Except the build data in TFS collection database, you also need to destroy the deleted source files to reduce the collection database size. We usually have three ways to destroy the deleted source files:
Execute the Tf destroy command, but it this files will be deleted later by a job run by the TFS Background Job Agent, this job usual runs only once a day!
Execute the Tf destroy with the /startcleanup switch which immediately kicks off the cleanup job.
Run the cleanup stored procedures manually. If your Content table is large: “exec prc_DeleteUnusedContent”. Please refer to the discussions in this similar post:

After the destroyed entries be removed from tables, please backup your database and then shrink it.
