Boost Your IT Operations with the Correct Levels of Data Backup and Recovery

Data backup and recovery goes hand-in-hand with data protection that needs several practices to be included while safeguarding the enterprise data. Protecting business-critical data against theft, attacks, corruptions, loss, and disasters is one of the major goal for IT organizations these days. Though the idea behind data backup and recovery is very simple, it needs an effective set and correct levels of backup operations to work seamlessly across the IT infrastructure. The lack of maintaining the correct level of data backup and recovery could result in companies adopting bad practices that might waste quite an enormous range of bandwidth, storage, and their valuable time. Let us understand these concepts and keep in mind while selecting a new data-protection product or services for the organization.

Data Backup Types and their Impacts:

Backup applications have a wide range of operations that vary depending upon the enterprise requirement. The most common data backup types are the full backup, incremental backup, and differential backup. Let us explore how they are going to help your organization while implementing the data backup and recovery services.

Full Backup: One of the most basic types of backup operation is a Full backup, where the backup is performed over the entire system, including every single file and application of the operating system. The primary advantage of a full backup is that a complete set of data is copied which results in minimal restoration time, known as recovery time objective (RTO). Whereas, the major disadvantages are that it takes very long to copy applications and require more storage space. Thus, it is advisable to run a full backup only periodically. Data center with very less critical applications or a small amount of data can run a full backup. Also, a strongly controlled environment that stores and loads data always at a specified place with a well-orchestrated solution can employ a full backup.

Incremental Backup: When an incremental backup is performed, it typically backs up all the data that has altered since the last backup. Usually, the incremental data backup includes a file-based backup that has been changed from the last backup. The challenge with the incremental data backup from data protection viewpoint is that admins attempt to minimize the I/O impact of data backups on the server and backups a 10 GB file just because 1 MB has changed, which is not an ideal practice. Thus, many vendors mostly prefer a block-based incremental backup method, which backs up only the specified blocks that have changed. The most common way is to backup VMware or Hyper-V using their APIs. This app notifies the appropriate API about the block-based incremental backup.

Differential Backup: Differential backup is the most widely used and accepted data backup procedure, which is similar as an incremental backup the first time it is performed. However, every time it runs afterward, it continues copying the data altered during the previously performed full backup procedure. This results in storing more data than an incremental backup, but far less than a full backup. It requires more storage and time than an incremental backup and less than the full backup.

To explain these types of data backup and recovery methods, we can take help of the comparison table given below:

No of Backups Full Backup Incremental Backup Differential Backup
Backup A All Data
Backup B All Data Changes from Backup A Changes from Backup A
Backup C All Data Changes from Backup B Changes from Backup A
Backup D All Data Changes from Backup C Changes from Backup A

A daily full level backup for organizations with small data sets provides a high-level data protection without surplus storage space costs. Enterprises with more volume of complex data prefer running a weekly full backup coupled with either daily incremental or differentials to have a better option. The differential backup is considered because of its higher level of data protection offering with less restore time with a small increase in storage demand. This is the reason why most of the organizations prefer using a strategy of weekly Full backups with a daily or regular differential backups.

Final Words:

Before considering any of the backup strategies, let us understand the importance of the fact that it is very crucial to first know when to use the strategy and how to deploy them depending upon the infrastructure of the enterprise. The user must know how these strategies can be combined with testing methodologies to meet the business cost, performance, and availability goals of the organization ultimately.
