SQL Server Backup Options: A Quick Roundup

In this article, we take a quick look at the several options available in MS SQL Server

Database Backups Under The Simple Recovery ModelThe SQL Server database is today counted as one of the best applications in its class. One of the key reasons behind its popularity is its robustness and backup features which enable business continuity.  Data backups are necessary to protect loss of data from many hazards like hardware malfunction, natural calamities or flaws related to media.

Prominent backup options available in SQL Server

  1. Full Back up option: It is a user friendly option as compared to other back up options like Differential back up and Transaction log back up. The reason for the same being that it is independent and supportive. It acts as a base for other back up variants. It contains a large amount of data, typically covering the active part of entire data repository, consisting of a set of files stored in a particular database.
  1. Database Backup

    Differential Back up options: They are comparatively smaller in size and also acquire less space. These databases are generally used for assuring data security. Differential Back up options is easy to handle because they can be created within a limited time frame. By using them one can store data in smaller amounts in different files therefore, enabling the user to save a lot of storage space. Differential backups can be completed in fairly short span of time as opposed to a full backup.

  1. Transaction Log Back up: As the name itself suggests it is an organised record or a log of transactions. There principal merit is that these series of transactions registered as a log can be retrieved in the case of technical errors. These are ongoing records, continuous in nature. It is constituted in such a manner that it comes out to be as a chronological log chain of the database.

It exists in two models:

The first being Full- Logged Recovery Model and the second one is called the Bulk-Logged Recovery model. Both these models allow the user to recover the entire series of recorded transactions. Therefore the database can be recovered easily in quick time.

Likewise the Differential Back up option, the transaction Log back up is not independent. They are to be compiled only after a full back up is created.  A transaction log back up has to be supported by a database back up. Nevertheless, it is highly convenient and accessible. It helps in preventing loss of data. It gets stored within a limited space, thereby saving your disk space and can be complied at regular time intervals.

While Backups are necessary you should also consider a SQL recovery tool

Creating full database backups is a necessary part of working on a SQL Server database. However just creating backups is not enough. To completely avoid data loss, consider keeping a sql server recovery tool like DataNumen SQL Recovery handy. This exquisite piece of software is equipped to bring back nearly all compromised database records with ease. Further it can be used recover sparse columns and recover comprised indexes too.
