In this article we share some handy tips to help you optimize your backup and recovery process
Often while backing up your SQL Server database, you might face problems which are complex in nature. As important is the process of backing up SQL Server data, equally important is the need to optimize the backup processes. If the process is not done right, without proper optimization, you might not be able to completely restore the backed up data or the whole process may end up consuming a lot of resource and time. To ensure that your backup processes are completely optimized, and allow complete restoration of backed up data; here are a few tips to help you do the same.
- Ensure software compatibility before upgrading – One of the most common problems that arise when backing up SQL Server data is the lack of compatibility between the backup application and SQL Server edition. The application that works fine with one given edition, might not work well with an upgraded version of the same edition. Therefore, before you opt for upgrading your SQL Server edition, it is important to ensure the compatibility of your backup application with the SQL Server edition you plan to upgrade to.
- Impacts of Backup compression – Backup compression feature was introduced in the 2008 edition of SQL Server, the effectiveness of this feature varies on the content of your database. Along with reducing the size of the backup, this feature also reduces the time taken for the backup, however these advantages have a cost! Backup compression takes up a lot of CPU power and is very CPU intensive. However this is not same for all backups, how much of the CPU is consumed depends on how much data can be compressed.
- Maintain integrity of the database – Integrity of the database often gets compromised in highly transactional environment, especially if you are using an old edition of SQL Server. It is very important to ensure the integrity of the database before you back it up, because this might lead you into backing up corrupt data. Make use of SQL Server Maintenance Plan Wizard to ensure that your database is not corrupt. This Maintenance plan allows you to create SQL Server Agents which work on checking for corruption in the database, through regular checks for internal consistency. Although SQL Server typically attempts to do away with data corruption on its own; but in-case of extensive corruption, it cannot heal itself. Sometimes it might also happen that after restoring a backup you realize that you restored a corrupted backup. In such situations, you will have to take assistance from third party sources to undo the damage.
Even a Well Planned Backup and Recovery Process may Not Work Optimally in Certain Situations
Despite our best efforts, even a detailed backup and recovery process may not work out optimally in certain situations. There may be cases where you would have to attempt a recovery directly from a crashed SQL file. In such cases you need a formidable sql server recovery tool like DataNumen SQL Recovery to bring back the entire set of records. This incisive tool can handle files as large as 16Tb and also supports batch repair.
