To answer that question properly it would be necessary to know the specific needs of each individual business or home, so instead let’s look at two fictitious scenarios which will serve as examples of ways in which a backup can be of great value. So now we have some information that will help us to establish and maintain a stable and successful backup routine, but some people might still be wondering whether it is really necessary to do it and why it’s considered so important. The following table contains estimated lifespans of various storage media: Medium One of the questions you need to consider when deciding where to save your backup copy is: How long am I going to need to keep this backup? Knowing the answer to that will make it easier to figure out which medium to store your files on. Backups have been variously done on punch card, floppy disk, optical media like CD, DVD and Blu-Ray, tape, external hard disk, cloud-based storage services, and more. The types of media most commonly used for storing data have changed over the years. Once you have decided which type of backup is best suited to your needs, it is important to consider carefully where to store it. For the same reasons as with incremental backups, we recommend that differential backups are also not carried out manually.

However, with this backup model, all the files created since the original full backup will always be copied again. Differential backupĪ differential backup has the same basic structure as an incremental backup-in other words, it involves making copies only of new files or of files that underwent some kind of change.

We recommend that you do not try to employ this type of backup strategy using manual means. As such, the incremental backup saves time and space, as there will always be fewer files to be backed up than if you were to do a full backup. The incremental backup will detect that all the files in the full backup remain the same, and will only make backup copies of the two newly created files. Once you’ve finished, you decide that going forward you will do incremental backups, and you then create two new files. For example, imagine you have done a full backup. This process requires much more care to be taken over the different phases of the backup, as it involves making copies of the files by taking into account the changes made in them since the previous backup. This type of backup is the first copy and generally the most reliable copy, as it can normally be made without any need for additional tools. Full backupĪs the name suggests, this refers to the process of copying everything that is considered important and that must not be lost.
In short, there are three main types of backup: full, incremental, and differential. In this article, we will look at the main types of backup operations, as well as at some of the most common mistakes that many of us may make while backing up our data. When this notion was adopted by people and companies within a technological context, its original characteristics did not change – simply, new resources became available to make the backup process easier and faster. This way, if the original became damaged, it was possible to recover the information it contained by referring to the copy, which was kept in a different, safe location. Whenever any important document or information was copied and stored in a place separate from the original for the purpose of ensuring the information would not be lost, the process of backing up was taking place. Of course, the concept of a backup existed long before it came to be named as such. What are the main types of backup operations and how can you avoid the sinking feeling that comes with the realization that you may not get your data back?Īs humanity’s use of all kinds of technology has grown, terms like backup are no longer unfamiliar to the majority of people.
