Transaction log backups in a SQL FILESTREAM database

March 5, 2019 by

In the continuation of our SQL FILESTREAM article series, we’ll be covering transaction log backups

In SQL Server, we take transaction log backups regularly to have a point-in-time recovery of a database. It is essential to define the backup policy with the combination of full, differential and transaction log backups. A standard configuration of backups for large databases in the production database environment is as follows.

SQL Server FILESTREAM with Change Data Capture

February 22, 2019 by

Sometimes we require tracking data change activity (Insert, update and deletes) in SQL Server tables. SQL Server 2008 introduced Change Data Capture (CDC) to track these changes in the user-defined tables. SQL Server tracks the defined table with a mirrored table with same column structure; however; it adds additional metadata fields to track these changes. We can use table-valued function to access this changed data.

SQL Server FILESTREAM and Replication

February 19, 2019 by

In the previous articles in this series (see TOC at bottom), we wrote about the various feature of the SQL Server FILESTREAM. In SQL Server, we use replication to replicate the articles to the destination server. Consider a scenario in which we have the FILESTREAM database in our environment. We would also have the requirement to configure this database for SQL Server replication.

In this series of articles on SQL Server FILESTREAM (see TOC at bottom), we explored various ways to store unstructured data in the file system with the metadata in SQL Server tables. If we have a large number of objects in the file system, it is advisable to use the fast disk for storage purpose. It is faster and provides better IO in comparison with the traditional file system.

Importing SQL Server FILESTREAM data with SSIS packages

February 1, 2019 by

Initial configuration

We have been exploring the SQL Server FILESTREAM feature in this ongoing series of articles. In this previous article, Managing data with SQL Server FILESTREAM tables, we wrote about inserting FILESTREAM data into a FILESTREAM table and performing DML activities on it. Suppose we have created the FILESTREAM database in our instance and now we want to insert a large number of files into a FILESTREAM container. It is easy to write out the insert queries for a small number of files, but if the numbers of files were in huge quantity, it would be difficult to write out the code and insert data into it. It is difficult to manage such kind of requests regularly in the environment.
