Although 90% of businesses perform data backups, 58% of data recoveries fail. By implementing 3 different types of backup methods, you could prevent your business from becoming another example of that statistic. Data breaches cost enterprises millions of dollars in loss, so taking the time to ensure your data is secure and safely backed up is taking the time to ensure that your finances are secure as well.
Full backups, incremental backups, and differential backups all play a role in securing your business data. When you know how often to implement each, you can guarantee that your business data won't be lost in cyber space when you need it at the most critical times.
Full backups are the simplest and most widely recognized. A full backup makes a copy of all data to a storage device. After making a backup of everything that needs to be protected, all files are copied over to a secondary storage target. If utilizing cloud-based solutions via a managed services provider, this would be off site. If using a traditional IT environment, this could be on tapes. It all depends on which environment you use.
The benefit of performing a full backup is that you have access to a complete copy of all your data and it’s all available within a single set of media. When restoring data that has been backed up like this, full recovery requires minimal time which is extremely beneficial for those with a strict recovery time objective (RTO).
Full backups use a lot of bandwidth to cover all files in the entire system and are, therefore, only run periodically.
An incremental backup stores only the data that has been altered since the last backup. Any data that has been covered by the full backup is not touched.
For example, let's say you ran a full backup on Monday. On Tuesday, you run an incremental backup to save the changes you've made since Monday. On Wednesday, you run another incremental backup. The incremental backup on Wednesday is only going to save the changes made since Tuesday. On Thursday, you run another incremental backup. The incremental backup on Thursday is only going to save the changes made since Wednesday, and so and and so forth. Each incremental backup is saved as a file all its own, referencing the last incremental backup made (which, when traced to the first incremental backup, references the last full backup).
Organizations may run this type of backup as often as desired. Because incremental backups copy a smaller amount of data than full, it results in faster backup speed.
Simply put, incremental backups occur after one full backup has been made and only the data that has changed since the last incremental backup gets backed up in this process. When restoring data that has been through this backup, you would restore the latest full backup set first. Then, each of the incremental backup sets would be restored in order. If one of these backup sets shows missing or damaged, then a full restoration isn't possible.
Many people get stuck on the difference between differential and incremental backups. While they do have a similar nature, they are slightly different. A differential backup saves data that has been altered since the last full backup as a full set of data.
Building on our former example, let's say on the following Monday you run a full backup. On Tuesday, you run a differential backup. The only data that would be saved in that Tuesday differential backup, is the changes that have been made since the last full backup (just like an incremental backup). Wednesday, you run another differential backup. That differential backup will merge with the differential backup made on Tuesday, and save the changes made as one backup set. Thursday, you run another differential backup. That backup will merge with the differential backups made on Tuesday and Wednesday, and save as one backup set (Tuesday-Thursday). Unlike incremental backups, you won't have to redownload each differential backup to perform a full backup. Instead, you would take the latest differential backup and then the latest full backup to complete a full restore.
These backups are not recommended to be carried out often, as the process takes longer, but they can provide businesses with moderate recovery and requires moderate storage.
Knowing where to store your data is also a key component to effective data backup implementation. It's also a key component of determining what your IT budget can afford for data storage and backups. By utilizing an IT managed services provider for your data backup needs, you can save time, money, and resources trying to run these backups in-house.
By utilizing cloud services with a trusted IT solutions/managed services provider, you can take advantage of data center experts that monitor your data 24/7, automate backups of your data in multiple locations, and regularly update software and hardware to ensure the security of your data.
