Backing up your organization’s networks, servers, cloud data, files, documents is very important. There are different types of data backup methods, each will address different risks, vulnerabilities and storage needs. Here are some types of data backups that companies commonly use.

Types of Data Backup
1) Full Data Backup
As the name implies, this method duplicates all data both stored in files and folders, including data that has previously been backed up.
Even though it sounds like the ideal solution, full data backup has drawbacks in terms of efficiency. Typically, this type of backup requires more time and space.
The time period used to recover data is also relatively longer. Compared to doing a full backup at one time, it is much more effective to back up data regularly or make this method a part of your backup system.
2) Incremental Data Backup
Incremental data backup only restores data that was changed since the last backup. This method is known to save time and storage space, hence it is often combined with full backups.
However, just like a full backup, the process required to restore data can take a long time because it often involves repetition of previous backups which of course require a complicated process.
3) Differential Backup
All changes made since the last full backup are backed up. It is much faster and requires less storage space than a full backup, but more than an incremental backup. Restores are slower than with a full backup but faster than with incremental backups.
4) Mirror Data Backup
Mirror Data backup is considered superior in terms of storage capacity and data recovery processes. However, this method cannot guarantee data security in case of loss or damage.
The reason is, only the original data is stored in the backup. If there are files that are lost or damaged, the data can also be lost in the backup process.

5) Full Synthetic Backup
Rebuild the full backup image using all incremental or differential copies. It can be stored on tapes in external locations, with the advantage of reducing restoration time.
6) Reverse Incremental Backup
It is an incremental backup of changes made between two instances of a mirror copy. After the initial full copy, each successive copy applies changes to the previous full copy, creating a new full synthetic backup each time, while maintaining the ability to roll back to previous versions.
7) Continuous Backup
It is also referred to as “real-time backup” as it backs up whenever a change is made. Continuous backup monitors the file on a real-time basis and backs up as soon as a change takes place on the file.
8) On-Site Backup
To perform the on-site backup, companies need storage space and special devices. The advantage is that on-site data backup offers maximum protection from viruses and hackers because the owner has full access to the data.
Unfortunately, it will cost you a lot to provide a large storage space, as well as the costs of anticipating a disaster.
9) Online Cloud Backup
Utilizing cloud computing technology, online backup methods are currently considered the most ideal for ensuring data security.
Online cloud backup is very useful, especially in terms of updating IT systems, changing the role of computers in the backup process, and avoiding the risk of theft or direct data destruction.
Cloud backup runs on a SaaS system which can simplify data management and real-time updates without having to disrupt the company’s operational processes.
