Let’s Discuss the Importance of Backup in SQL Server

There should be proper planning done to create backup of SQL Server Database. As all the data saved within the database is prone to get corrupt in several ways such as any human error, network intrusions, natural catastrophes, poor power outrage, any hardware failures, etc can damage your most crucial data, thereby leading to data loss or data inaccessibility issue. Hence, here comes the importance of backup in SQL Server. So, let’s elaborate it and make the best use of this article.

Importance of Backup in SQL Server

In order to minimize the risk of disastrous data loss, it is wise to take backup of the SQL databases. This backup file will help to preserve from any modifications that may happen while working with SQL Server on a daily basis. Therefore, a well-planned backup will definitely help a user to protect the database against data loss that may happen due to different failures. In short, taking a backup copy of the database is the only way to protect the data.

If a user takes necessary actions after understanding the importance of backup in SQL server, then he/she can redeem the data from various failures like media failure, user or human errors such as dropping a table by mistake. While coming to hardware failures, it can a corrupted disk drive or a permanent loss of server. Other failures can be due to natural disasters. Additionally, whenever a backup copy of the database is taken, it will be extremely useful for the routine administrative purpose like copying a database from one server to another server. Basically, backup is nothing but a copy of data that can be used to recover the files after the occurrence of any catastrophes.

As we understand that backup is a replica of information, hence simply copy and pasting the MDB(Master Database File) won’t work. A user must run a process via the backup command within the SQL server. This will help to create a complete, page-by-page copy of the database, which includes even every single object of the database.

Different Objectives of SQL Server Backup

Instead of focusing on the importance of backup in SQL server, a user should also ensure to carry out the backup process accurately. Also, storing and maintaining them at the right location. As a wrongly done backup process is anyways more harmful than no backup at all. Here are the major points that is to be understood by a user while initiating the backup process.

Maintain the Frequency: A disaster is always an unwelcome guest. Hence, this has to be made clear at the very first itself, as you cannot go for weekly backups if the organization does not want to lose a single day’s work. Therefore, it is suggested to backup the database on a daily basis for full backup, including the log backups and differential backups. Demonstrate the Backups: As it is always said that prevention is better than cure, similar such theory applies for backup. Once the backup file is created and also stored at the safe location. A user must implement certain restore commands so that it will be easy to recover the files if any disaster occurs in future in a straightforward manner. Risk-less Storage: Usually, the backup file is stored in the local drive. However, the data stored in the drive is also not that safe enough as it is also inclined to data corruption. Moreover, a user must be clear about the number of files and copies of the backup stored. Backup to be Retained: It is often that most of the users while deleting unwanted data may also unintentionally delete the backup file of the database. Hence, make sure that you follow the retention policy and not delete before its right time. Also, use DBCC CHECKDB command to verify that the backup file is not undergoing any corruption. In order to reduce the storage size of the backup file, use compressor so as to occupy less space An Expert Approach to Recover Data from Corrupted Backup File

Although, after following all the above described approaches to maintain the backup file properly, still if in case the backup file itself has got corrupted. It will be a huge loss as it is a challenge to restore the lost files from the backup file. Under such circumstance, do not get panic instead simply switch to the efficient utility named, SQL Bak File Repair . It is a top-notch tool comprising of power-packed features that helps to restore and export the corrupted backup file(.bak) to SQL server in no time. It also ensures to recover the MDF and NDF file from the damaged backup file. Moreover, it can support the backup file recovery of SQL server 2014 and all the previous versions.

Concluding Words

While working with SQL server, as a precautionary act it is important to backup the SQL database as we have clearly discussed about the importance of backup in SQL server. Considering this aspect, we have described various objectives that is to be kept in mind while dealing with the backup file. Apart from that, if the backup file has got corrupted by any means, then simply adapt the automated tool to restore the files from the backup file instantly.
