It is an unfortunate reality that disaster can strike at any time. Database corruption, hardware failures, and natural disasters are just a few of the situations that threaten your company’s data on a regular basis. No matter how diligent your organization is with performing on-site backups, your data will always be vulnerable. That is why it is recommended to keep one or more backup copies at an off-site location.
Backing up copies of data off-site means backing up to a location that is in another city or state. It should be far enough away from the original copy, so that if a natural disaster were to occur, it would be unlikely to destroy both copies. When backing up copies off-site, data is usually transported using removable storage media such as magnetic tape or optical storage. Data can also be sent electronically via a remote backup service, which is known as electronic vaulting or e-vaulting.
In the event disaster does occur, keeping one or more backup copies off-site will significantly decrease the risk of downtime and get your organization up and running as quickly as possible.
In the clip below, Symantec explains the importance of keeping one or more backup copies of your data offsite.
Keeping one or more copies of data off-site has become such a commonly practice in backup and recovery, it is one of the three components in the widely recognized 3-2-1 Backup Rule. The 3-2-1 Backup Rule is popular IT concept that will help ensure that your data will last.
The 3-2-1 Backup Rule is defined as:
- 3 Copies of Data
- 2 Different Types of Backup Media
- 1 Backup is Stored Off Site
3 Copies of Data
Be sure to have three unique copies stored in three different places of any data that you want to protect, including bare metal images, databases or files of any type. Besides the obvious advantages of having additional copies of data to mitigate risks of losing all backup, multiple copies of data can be stored in multiple locations.
2 Different Types of Backup Media
Two different formats means at least two different methods to store data are used. A combination of various media, whether tape storage, backup appliances, cloud storage, is therefore recommended.
1 Backup is Stored Off-Site
This is the critical copy that can be used to restore your system in case of a disaster where your IT resources are seriously compromised or destroyed. This process involves backing up your data to convenient storage formats, moving it to an offsite location, and frequent testing to ensure you can quickly restore it after an incident.
