One of the most disastrous things that can happen to a company in the digital age is lost data,which can result in downtime. Downtime can be devastating for any company, and the scale of its effect to the size of the company. Statistics have shown that a small company might lose $8000, a medium company could lose $74,000, and a large enterprise could lose $700,000 with just an hour of downtime.
Statistics further show that 93% of companies that lose access to their data and assets for 10 days or more end up filing for bankruptcy within twelve months of the incident. This is why it is important to invest in network security to prevent tampering and mitigate the effects of human error, hardware failure, and natural disasters.
One important aspect of network security is running regular backups to prevent data loss, but running a backup has come far from simply putting copies of your company assets in another location. As the management of a company becomes more complex in a digital sense, so does the process of backing up and securing their data.
And with the growing complexity faced in backing up your company assets, many backup as a service (BaaS) providers have grown intensely in popularity, given the intense need for data protection in a company’s information systems.
The Three Types: Full, Incremental, and Differential
As suggested by the name, a full backup is a copy of all of your organization’s data assets, into a single version. An incremental backup, on the other hand, covers all files that have been changed since the last backup was made. And a differential backup is a cumulative backup of all files that have changed since the last backup.
Each type has its own pros and cons, which will be explored further in this article.
The Full Backup
While the full backup is still a regular practice in the management of the information systems of many organizations, it is usually executed less frequently than other types—weekly or biweekly at the most.
Some of the pros of full backups include:
- Potential for a fast and total recovery of data assets
- Easy access to the most recent version
- There is only a single version to consider
- Easiest to use if the need for data restoration in the information system arises
And some of the cons are:
- It takes up the most storage space
- It is heavy on bandwidth
- It consumes the most time.
The Incremental Backup
This is normally done in conjunction with the full backup, with the full backup done on one day and an incremental backup done on another.
The pros of the incremental backup are:
- It takes the least amount of time to perform a backup
- It requires the least storage space
- Its demands on the bandwidth are the smallest.
And some of its cons:
- Recovery time may take longer
- It needs to be partnered with full backups anyway for complete recovery
- Recovery may involve a complex process of fitting pieces of data together from multiple backup sets
- There is a potential for incomplete data recovery.
The Differential Backup
This is another type of backup that is usually used in combination with the other two. Some of the pros of the differential backup are:
- It requires less storage space than full backups.
- Only the last full backup and the most recent incremental backup are required for a full recovery.
And the cons are:
- It is slower than the incremental backup
- It still needs to the initial full backup for complete recovery
- It needs to piece together two sets of backups
- If one of the other backups is incomplete, the recovery may fail
But what is the best choice for my company?
There is no single answer to this question, and it depends entirely on your company’s needs and preferences. Some companies do a daily full backup, while others employ a combination of these strategies. At the end of the day, any combination of these solutions can prevent and solve the problem of data loss if employed with the correct strategies.
