Today every major organization has its data stored in electronic form. This data is accessible in various forms through a computer. Such data can be anything from various MIS to employee information, to sales graphs, etc.; this data is known as the database of an organization. Every company today has its own database and strives hard to maintain it on a high accuracy level. While SQL is a programming language used to maintain a database in an electronic system. Most of the time, it is done with the help of computers only but today due to use of high technology database can be easily managed from tablets.
As all the electronic systems are prone to damage or virus, even SQL server database is not alien to it and can get corrupt or affected by the virus also it can be damaged due to electronic server issues or manual mistakes. In order to avoid these problems, it becomes mandatory to maintain a backup for database SQL servers.
Things to keep in mind before doing the backup procedure
- Having a clear idea about backup strategy
To get a backup done, it is vital to have a recovery model and once you have chosen your recovery model you need to make and execute a strategy which will prove useful for your database depending upon the company’s requirements. These strategies are to be made by considering various factors such as the required disk space, the number of hours a database is accessed, the number of changes made and the frequency of changes, the specific areas of the database where changes are made, etc. Considering all these factors makes it easy to make an effective strategy which gives productive outputs.
- Selecting the data which is to be backed up
Yes, all the data which is maintained in the database is important, but it is not necessary that all the organizations look forward to backing up all the existing data. Many times, to avoid the time occupancy and also expenses the companies prefer to back up only that data which is very curtailed and cannot be gained again. So before implementing the backup process do analyze and segregate the data which is to be backed up.
- Implementing backups at the right time
Once all the strategies are done, data is sorted, etc. an ideal time for backup is to be decided. Huge database backup cannot be performed at a time where the server is low or is accessed by many people; so mostly SQL database backups should be executed when the server and electronic conditions are favorable for the same.
- Checking the backup
Before doing a backup of huge files, you can small backup files and see how it is working and also analyze how long it takes for the backup process. Based on the previous performance further backup activity should be carried on.
A decision on hiring database management services: today many companies are handing over their database to database management companies who manage A-Z of the company’s database. These management companies maintain the data on high accuracy with various backup options. Remotedba.com is one of the leading companies in the database management system. So, the decision should be taken on prior bases whether to hire database management services or not to depending upon the company’s budget and willingness to spend on SQL database management services.
