What Is a Full Backup?<\/h2>\n
A full backup is one that stores a copy of the entire selected dataset. In other words, it entails sending all the data to the backup storage. It\u2019s that simple and straightforward.<\/p>\n
But \u2013 get this \u2013 in most cases, full backups are only performed once, at the beginning of the backup process. That provides a foundation for running other types of backup on subsequent occasions. Otherwise, it would be cumbersome to perform full backups every single time.<\/p>\n
Further reading<\/span> Types of Backup<\/a><\/p>\n Incremental Backup is all about sending copies of only new and altered data blocks (since the last backup instance) to the backup storage. This is usually performed to quickly update the previous version of data in the backup storage. And, in most cases, it\u2019s used on regular data, as well as image-based datasets.<\/p>\n Further reading<\/span> Incremental Backup Explained<\/a><\/p>\n Differential Backup, on the other hand, isn\u2019t exactly meant to update the last backed-up version. Instead, it sends in copies of all new and modified data since the initial full backup instance. Consequently, backed-up data continues to grow in size with each differential backup instance.<\/p>\n Further reading<\/span> Differential Backup: A Full Guide<\/a><\/p>\n A synthetic full backup is a form of full backup that\u2019s usually performed to update data that was already backed up in full.<\/p>\n Unlike regular full backups, though, it doesn\u2019t simply re-upload copies of all the data. Instead, it compares the copies that were already backed up with the data on the source machine, and then proceeds to transfer only copies of the modified data from the machine to the backup storage.<\/p>\n The unchanged data blocks, on the other hand, are replicated within the backup storage and then combined with the uploaded modified copies to establish a new fully backed-up dataset. This, in the end, makes synthetic full backup much faster and more convenient than performing a complete full backup.<\/p>\n Further reading<\/span> Synthetic Full Backup: How It Works<\/a><\/p>\n Seems strange, I know, but don't make the mistake of confusing backup methods with types of backup. While the latter focuses on various backup methodologies, the former is all about the different approaches used to back up data. You could also think of them as backup techniques.<\/p>\n That said, there are three primary data backup methods: file-level backup, system state backup, image-based backup<\/a>, application-aware backup, and VM backup.<\/p>\n File-level backup is a technique that organizes the data into separate files. So you should be able to conveniently upload different files of data from the source machine to the backup storage.<\/p>\n Further reading<\/span> File-Level Backup Best Practices<\/a><\/p>\n Unlike file-level backup, system state backup attempts to save copies of the source machine\u2019s critical system files. This is where you back up the operating system along with all the accompanying system configurations.<\/p>\n Further reading<\/span> System State Backup Explained<\/a><\/p>\n Image-based backup is a special technique that copies the source machine\u2019s hard drive data along with all the associated configurations, and then saves them in the backup storage. This allows you to perform recoveries from the hard drive images.<\/p>\n Further reading<\/span> System Image Backup and Recovery Guide<\/a><\/p>\n Application-aware backup is intended to back up the full state of special applications. It copies and saves application data along with its associated configurations at a specific point in time. With that, it becomes easy to fully restore applications in their full state.<\/p>\n Further reading<\/span> Application-Aware Backup<\/a><\/p>\n VM backup<\/a> seeks to transfer copies of data from virtual machines and then save them in the backup storage. The architecture here is, of course, different compared to local machines, and the whole procedure happens to support block tracking.<\/p>\n Further reading<\/span> Virtual Machine Backup Best Practices<\/a><\/p>\n Here are a couple of pointers you should keep in mind while selecting the appropriate backups for each occasion:<\/p>\n Further reading<\/span> Backup Plan: The Ultimate Guide to Saving Your Data<\/a><\/p>\n The fact of the matter is, you should back up every last piece of data in your system. There are no exceptions.<\/p>\n While you\u2019re at it, though, please remember that each type of data should be treated differently.<\/p>\n For instance, the backup frequency itself is not the same for all the files; it varies depending on how \u201chot\u201d the data is. And when it comes to that, there are three main classifications for backed-up data:<\/p>\n Another way to look at it would be:<\/p>\n Further reading<\/span> Compare AWS, Microsoft Azure and Google Cloud for Backup<\/a><\/p>\n For the best possible outcome, you should;<\/p>\n Further reading<\/span> Local, Cloud and Hybrid Network: Which One Should You Opt to?<\/a><\/p>\n Further reading<\/span> Data Backup Best Practices<\/a><\/p>\n The 3-2-1 backup strategy attempts to seal potential data loss loopholes by spreading out your backup copies across different storage locations. That means you can recover your system from multiple backup locations.<\/p>\n In essence, you should have at least 3<\/strong> copies of your data: 2<\/strong> backed up locally in different devices; and 1<\/strong> stored in an offsite backup location, such as the cloud.<\/p>\n Further reading<\/span> 3-2-1 Backup Strategy<\/a><\/p>\nWhat Is Incremental Backup and Differential Backup?<\/h2>\n
