Steps to reduce (or slow the growth) of the database size.
Warning: Ensure there is a full backup of the DAS database before proceeding, and before each additional step:
use DAS; DBCC SHRINKFILE (N'das_log' , 0, TRUNCATEONLY);
Note: The database may need to be shrunk again if changes were made, or after Zero Prevalence Pruning has had several days to work through changes.
