What is Data Backup?
Data Backup is a process or technique that involves saving a copy of the original data. This helps the user to retrieve the data when there is a data loss. There are different types of data backup options available to help organizations secure their confidential data:
Backing up of data is done by two categories of people
1. People who regularly take backup in advance to ensure prevention of data loss and
2. People who implement data backup only after experiencing a data loss.
Businesses that do not have a structured data backup plan are vulnerable to data loss — a security incident that requires a lot of time and money to recover. With the constantly changing needs of the enterprises, data backup can be adopted and implemented in different ways.
Following are the most commonly used types of data backups
Full data backup
This type of data backup involves the process of creating a copy of all the data in your database. Full data backup is a powerful and efficient method as it enables the user to recover the lost data at any given time.
However, there are a few challenges with data management when it comes to full data backup. Managing the complete data can be a daunting task as it may require adequate storage space to facilitate the backup of full storage. Recovery of data can be time-consuming depending on the amount of data.
Incremental Data Backup
This type of data backup involves backing up of recently added/modified files to the existing backed-up database. This type of technique can be done quickly, and the backup process takes less storage space in contrast to full backup. However, the disadvantage of this type of backup is that the restoration of each backup is processed separately which is time-consuming when compared to the full backup.
Differential Data Backup
Differential data backup helps to back up the files that have been changed since the last full backup process. Though it is almost similar to the incremental data backup, however, the differential data backup takes minimum time for storing the data.
However, the disadvantage is that the differential data backup might require a scalable storage system as the data backup can grow larger than the actual full backup version.
Mirror Data Backup
Mirror data backup is almost the same as a full backup process – however, the only difference is that the files that are backed up are not zip compressed. Mirror data backup is protected with passwords where users can gain access to tools like Windows Explorer. The major advantage of mirror backups is that the backup and restore time can be done quickly. However, this option may tend to occupy more space on the servers.
Each type of backup plan comes with a specific set of purpose to fit various business needs. The best approach is for businesses to deploy a custom-made data backup plan.
