2 Quick Tips to Speed up the SQL Server Backup Process

In this article we look at ways to the speed up the SQL Server Backup process

Speeding Up The SQL Server Backup ProcessWhen using SQL Server, backing up data often becomes a task that most DBAs would want to run away from. But this cannot happen, because backing up data is most important aspect of maintaining databases. Why backups do not form the interesting part is because, they often take really long to complete, and this is not one of those processes that you can simply skip as they are needed in SQL Server database recovery. To prevent backups from being the really time consuming task that it is, one can opt for speeding it up. Given below are two different ways, using which you can speed up the backup process in SQL Server.

Increasing the Speed at Which Data is Read from the Disk

AlwaysOn Availability GroupsIf the data from the disk is read faster, the backups can be done a lot faster. But to be able to do this, you will first have to make a lot of efforts, firstly your drives need to be faster, your storage needs to be tuned and the data needs to be compressed. Once all this is done, your backups will automatically become faster. If your files are compressed, you have sufficient disk space and updated drives; there is nothing there to prevent you from having quicker backups.

To make thing more organized, you can archive unused data. If you’re using AlwaysOn Availability Groups, it is advisable to use the replica that is easily available, use lesser amount of data for backup. Further do not go for full backup on a daily basis and consider performing them just once a week or even a month. You can replace regular full backups from differential backups, to backup the recently made changes, after full backups. However, only using differential backups, without a full backup, will not help. It will be done quickly, but the backup won’t work.

Increasing the Speed at Which the Data is Written on the Disk

This is another technique that can help you backup data faster. Once you know how to quickly read data from disk, knowing how to quickly write data on disk, will only make it better. One of the most important things here is Compression; you can either use the default compression or a third party software. Ensure that the CPU consumption is not too much, but the results should be worth it. Compression will make your files smaller, thus making them quicker to be written.

Another very important tip to enable quicker backups is to split them. If you write your backups in multiple files, you can improve the backup throughput by multiple factors. And striping backups makes them a lot quicker. After you are done with tuning your backups, you switch to tuning your restores, because that is equally important for faster backups. A faster backup is of no use if the restore process is time taking. Along with quicker backups, you also need quicker restore options for your backups.
