Truncating MSSQL Transaction Log

The instructions below only apply for AhsayOBM version before 9.5.0.0 and database with full recovery model.

Since AhsayOBM v9 utilizes VSS-based backup, which does not support log backup (A Guide for SQL Server Backup Application Vendors), transaction log of database in full / bulk-logging recovery model may eventually fill up all disk space available on the volume.
