The only way to tackle data loss incidents is by putting a solid backup strategy in place. In fairness, most companies today do back up their data rather diligently. Yet, one-third of them experience problems with backup restoration. For the majority, a backup strategy starts and ends with what to backup. The former gives you a backup strategy while the latter gives you the right backup strategy. A full backup is the most complete type of backup where you clone all the selected data.
This includes files, folders, SaaS applications, hard drives and more. The highlight of a full backup is the minimal time it requires to restore data. However, since as everything is backed up in one go, it takes longer to backup compared to other types of backup. The other common issue with running full backups is that it overloads storage space. This reduces the burden on the storage space, increasing backup speed. A differential backup straddles the line between a full and an incremental backup.
This type of backup involves backing up data that was created or changed since the last full backup. To put it simply, a full backup is done initially, and then subsequent backups are run to include all the changes made to the files and folders.
It lets you restore data faster than full backup since it requires only two backup components: an initial full backup and the latest differential backup.
Day 2 — Schedule a differential backup. It will cover all the changes that took place between Day 1 and Day 2. Running a full backup on a daily basis requires more than twice the storage space of differential or incremental in many cases.
At most organizations, the difference is significant. For some organizations, running a full backup daily is actually the most cost-effective approach. These are typically organizations with minimal data assets, which can be a product of their industry, products, services, or a lack of multimedia data assets.
If cost and storage space factors are not prohibitive, a full backup represents the easiest and fastest recovery. Your company's need for risk management, total volume of data assets, and other factors can all have an impact on the approach to backups that's right for you.
While some organizations demand full backups on a daily basis, others are best served with a weekly full backup and daily differential backups.

Differential Backup A full backup is a total copy of your organization's entire data assets, which backs up all of your files into a single version. Pros and Cons of Full Backups Few organizations run full backups on a regular basis. Pros of Full Backups Potential for fast, total recovery of data assets. Simple access to the most recent backup version. All back-ups are contained in a single version. Minimal time needed to restore business operations. Cons of Full Backups Requires the most storage space.
Demands the most bandwidth. Relatively time-consuming to complete the backup process. Pros and Cons of Incremental Backups If your business runs a full backup on Friday and an incremental backup on Monday, the incremental backup would copy all files changed between Friday and Monday. Pros of Incremental Backups Minimal time to complete backup. Requires the least storage space. However, if you cannot go very long without access to your data before losing business or profit, and your recovery time objective RTO is very small, consider using a differential backup instead.
Differential backups are a compromise between performing regular full backups and regular incremental backups. Incremental backups require one full backup to be made.
Afterward, only the files that have changed since the last full backup are backed up. This means that to restore, you only need the latest full backup set and the latest differential backup set. It also takes up less space than incremental backups, but more space than full backups.
Now that you understand the three main types of backup methods, you should also consider that there are many other types of backup methods that are based upon these. Some of them include the virtual full backup, near-continuous data protection, reverse incremental backup, and forever incremental backup. One of these may be ideal for your organization. Sometimes data protection needs more commentary. Browse our blog for tips, musings, commentary about industry news, and occassional product news.
