With data looked on as more of an asset than ever organizations are finding that their data backup and recovery system needs to be comprehensive. By knowing more about backup and recovery, you stand to be able to plan the solution to meet your company’s needs. Today, we will look at the different types of data backup and introduce you to four terms you need to understand.
The Types of Backup
There are various types of backup that anyone looking to come up with a backup strategy should know. They include:
- Full backup – A method of backup where all selected files are backed up in their entirety. Typically, the first backup taken for any backup solution. Since it is a comprehensive backup of all selected files, it will take more time than other types of backup. If a full backup is the method your organization chooses, then backups will typically be done after business hours, as long wait times will likely cause downtime.
- Differential backup – A method of backup that just backs up the changes made to data. While this allows for significantly faster backups, it makes for slower restores.
- Incremental backup – A method of backup that is much like the differential backup. The main difference is that the incremental backup backs up data regardless if the previous backup was a full backup or an incremental backup.
- Mirror backup – A method of backup that is a real-time duplicate of the source being backed up. In essence, it is total redundancy. One problem with a mirror backup is that if material is deleted by mistake, then it will be deleted on the mirror backup as well. For this reason, many professional IT technicians do not consider the mirror backup to be a viable backup solution at all.
Now that you understand the types of backup, here are some other backup-related terms that you should know:
- Business continuity – As the name suggests, it is a plan that is put together by a business that will allow it to continue effective operations if hit with any number of unfortunate situations. Normally focusing on a critical business functions, business continuity should be a strategy that every business prioritizes.
- Disaster recovery – As with any other security process, disaster recovery is a dedicated plan to protect your business in case of some significant data-based disaster. Anything from cyberattacks, to sabotage, to mistakes can cause major problems for your business.
- Recovery Point Objective (RPO) – As a part of a dedicated disaster recovery system, RPO is a benchmark indicating which data must be recovered for your business to resume normal business operations.
- Recovery Time Objective (RTO) – Also as a part of a disaster recovery system, RTO is the time your business needs to have its data back before the business becomes untenable. The lower the number, the faster you will need a full restore.
