There is a full backup and only changed data will be added afterwards. It works the same way as incremental backups in the beginning. Every increment will need to have backed up successfully to ensure the data set is complete, otherwise all following increments may fail to restore.Ī differential backup is a mixture of a full and an incremental backup.Restoring data takes a little longer than with full backups as the full backup will have to be restored and then each following increment will also need to be restored.Low storage requirements in comparison to full backups.Monday through to Saturday will then just backup any changes made to files each day, as to not interrupt operations and make the data a lot cheaper to store in the cloud. For example, you may do a full backup once a week, let’s say on a Sunday when there are the least amount of resources being used by employees. All your eggs are in one basket, so to speak, meaning if it is compromised you could lose everything, although this is mitigated through other protections.Īn incremental backup is when only changes to a data set are backed up, decreasing the amount of time and resources needed to perform the backup.Simple for storage and management due to it being a single data set.Fastest way to recover data after a disaster.These reasons are why backups are normally a combination of many types of backup, starting with a full backup and then moving onto other, smaller and less intensive, backup methods. A full backup is a large volume of data to be backing up every day, so not only could it interrupt operations, but it will also be taking up a lot of space in your data storage. It may seem tempting to do a full backup daily or perhaps even more frequently, but this can be very resource intensive and take a long time in comparison to other data backup methods. This is the best backup to have available to you as it is the simplest and speediest way to get your data back after a disaster. The name might give it away a bit, but a full backup is a copy of the entire source data set. Full backups, incremental backups, differential backups, mirror backups… which one is right for you and what are the advantages and disadvantages of each one? There are so many different ways to backup your data.
