It is recommended that a copy of data backup be stored at an off-site location to fight against cyberattacks from viruses or malware; human mistakes like wrong operations, accidental drops, or theft; and natural disasters like fire, flood, and outages.
What Is Offsite Backup?
Offsite backup, also known as off-site data protection or vaulting, is the strategy of sending crucial data out of the main location (off the main site) in computing. Usually, critical data is transferred offsite to remote servers like an online cloud usually via the network. Offsite backup is a part of the disaster recovery plan.
Important data can also be transported electronically relying on a remote backup service, which is also called electronic vaulting (e-vaulting).
Saving data copies off-site enables systems and servers to be restored after any disaster such as system crash or accidental mistakes.
Some organizations create and maintain their own off-site backups. Yet, most other organizations choose to rely on a third-party professional service to manage and store their offsite backups.

What Is Onsite Backup?
On the contrary, on-site backup means to save the backups periodically on local storage devices like external and removable devices like magnetic media (including HDDs, SSDs, USB flash drives, thumb drives, SD cards, tapes, etc.) and optical discs (including CDs/DVDs).
Offsite Backup vs Onsite Backup: Pros and Cons
Comparing on site backup and off site backup, both have their own advantages and disadvantages.
Advantages of Offsite Backup
- Data access flexibility: anywhere
- Data is available for many different remote locations by sharing or saving on different devices
- Data is safe if the main computer is destroyed or theft
Of course, off-site backup has some disadvantages. It is inconvenient to access the data stored offsite and a network is needed to access offsite files. What’s more, it may cost you a certain period to restore data from offsite devices after disaster depending on Internet bandwidth.

Advantages of Onsite Backup
- Convenient data access: anytime
- Internet access is unnecessary
- Quick data recovery if the hard disk drive storing backups is still available after accidents.
- High processing speed
- Easy installation
The biggest disadvantage of on-site backup is that if an accident happens to the main machine, all data will become victim including both source and backups. Besides, onsite backup is vulnerable to virus attacks.
Onsite Backup vs Offsite backup: Which to Choose?
Off-site backup and on-site backup, which one to select? In general, it all depends on you! For different people, the situation is unlike. So, some may find on-site backup useful while others may think off-site backup is better.
The practical backup and disaster recovery strategy could play an important role in an enterprise's life and death sometimes.
If you would like to maintain your data by yourself and tend to use it quite often, you should choose an onsite backup. Vice versa, if you don’t want to spend time on the troublesome data management and don’t use some files frequently, you can store them offline.
Or, for different sorts of files, you can perform different backups to them. For files that you frequently used, just keep an onsite copy. For those files that you don’t use too much, you’d better store a copy of them offsite somewhere safe from physical disasters.
Or, if you have enough onsite and offsite storage space, you can create two backups of all your data with one backup stored onsite and the other offsite. Yet, usually, few people have enough storage space to do that.
