This article will cover the process of analyzing and predicting/forecasting the size of a SQL backup as a means to better handle/manage retention of backups.
One of the main database management tenets is “Do not lose your data”. According to this; a database administrator incurs huge responsibilities to protect data. Under these circumstances, taking database backups and archiving SQL backup files is a key task for database administrators. In data protection strategy, taking database backups and archiving backup file processes play the leading role. Especially, backup planning is very significant for disaster recovery scenarios because backup file will be used for restore operation after any failure or data corruption. For this reason, every dba must generate recovery strategies for possible disaster scenarios and ensure that these scenarios can be solvable. At the same time, these backup files must be tested for data integrity; thus process provides to evaluate the recovery time and integrity of backup files. In this Backup and Restore (or Recovery) strategies for SQL Server database article you can find all details about backup and restore strategies.

This article will explain detailed usage of parameters in mobile reports in SSRS. Parameterized reports are important because report readers want to filter and customize their report data with parameters and this option helps report readers to focus on particular data. A parameterized SSRS report uses parameters as an input value and filters the report data according to these parameters. In this article we will focus, in particular, on how to use parameters and data sources together and how can we manage the parameters in mobile SSRS reports.

Performance monitoring is a very significant and essential topic for database or system administrators. This is no different with SSRS load testing. In some cases, performance problems can lead to significant system downtime. Most of the time in the background of the problem is having insufficient resources or improper settings. Therefore, before experiencing performance issues, we have to take some time to review preventive measures related to current system configurations or new installations. The load test (or stress test) is the most commonly used approach to tune systems before real-life staging conditions. Now we will discuss the details of load test, and in particular SSRS load testing.

Every once in a while, teams from different functional areas of the business (i.e. business intelligence, software development, web development etc.) would join forces to form a cross-functional development team with a common goal of integrating a business intelligence artefact such as a SQL Server Reporting Services (SSRS) report into a front-end web application. There are many reasons for forming such a partnership including a lack of report-development skill by web developers, BI team owns a better reporting tool for data visualization, or maybe to prevent the software team from “reinventing the wheel” by developing a report that has already been produced elsewhere.

As developers of business intelligence solutions, we tend to service different types of business users. Whilst a call center supervisor is more likely to consume reports that offer detailed breakdown of day-to-day performance of her call center agents, senior managers on the other hand often prefer big-picture analytical reports that represent data in a form of colorful graphs and charts. Not surprisingly, such reports often make use of heatmap controls to provide visually effective comparative view of business metrics against set targets.
