The main function of a database administrator (DBA) is to maintain the database. Indexes play an important role as they are one of the important aspects of high performance in SQL Server. Mainly SQL Server maintains indexes after any data modifications, still, maintenance of indexes is still required, due to Fragmentation. Index fragmentation affects the performance of SQL Server, so it is recommended to monitor the level of fragmentation. Index fragmentation occurs in the form of gaps in data pages and logical fragmentation. Thus, the only way to remove the unnecessary space and logical fragmentation is to restore indexes in SQL Server.<\/p>\n

In the following segment, we are going to discuss a step-by-step procedure to let users understand how to rebuild indexes in SQL Server in an absolute manner. Before that, let us know when and how often should you restore indexes in SQL server.<\/p>\n

When to Rebuild Indexes in SQL Server?<\/h2>\n

As the indexes become fragmented so, the performance of all indexes is degraded. The Rebuild Index task is a very good option to rebuild indexes to remove the logical fragmentation and free space, and update statistics. It is important to schedule tasks for timely rebuilding indexes in SQL Server database.<\/p>\n

Otherwise, the Rebuild Indexes in SQL Server will become a resource-intensive task. Moreover, if the index gets rebuilt, locks can be placed on the index, prevent someone from accessing it while rebuilding occurs. If anyone tries to access the index in order to return actual results can be temporarily blocked before the rebuild is complete. For instance, the Rebuild Index task is examined the offline activity, to be run when some people want to access the database. Generally, this means during the scheduled maintenance window.<\/p>\n

Nightly, if needed:<\/strong> If the index gets fragmented fast, and users have a maintenance window every night that allows to run Rebuild Index task, with all other maintenance tasks; then do so. The index fragmentation will degrade the overall performance of each index. As such, users have a nightly maintenance window, rebuilding will not harm, and also help to boost the performance of the server.
\nWeekly, at minimal:<\/strong> If users cannot perform this task every night, then, at minimum, it will run once a week, during the maintenance window. If users can wait more than a week, risk hurting the SQL performance due to the negative effect of empty space and logical fragmentation.
\nConsider other alternatives:<\/strong> If users do not have a maintenance window long enough to run the task at least once a week, then they can consider other alternatives like :<\/p>\n

How often to Rebuild Indexes in SQL Server?<\/h2>\n

The speed of index fragments depends on how it is used and will vary from one database to another. Let us consider the percent of index fragmentation:<\/p>\n
