Off-site backups, also known as offline backups, refer to copies of data stored physically outside of a main office or facility where the primary data resides. They provide an extra layer of protection by ensuring that if the primary systems are damaged or compromised due to events like fires, floods, hardware failure, hacking, ransomware, or other threats, an intact recent copy of the data exists securely in another location. With only on-site backups, all copies of data could potentially be affected by a localized disaster or attack, leading to permanent data loss. Off-site backups guard against this vulnerability by maintaining the data in a secondary protected location. As cyberthreats become more common and catastrophic events seem to occur more frequently, implementing a reliable off-site backup strategy has become an essential best practice for businesses, organizations, and even individuals seeking to keep their data safe and recoverable.
Risks of On-Site-Only Backups
Relying solely on on-site backups comes with considerable risks. If a fire, flood, or other disaster occurs at your office location, both your live data and backups can be permanently lost if the backups are stored on-site. According to experts, “Vandalism and theft are risks with both onsite and offsite backup, yet they pose a much bigger danger when only onsite backup is used. Storage media and hardware are attractive targets for thieves” (https://blog.etech7.com/backing-up-your-data-onsite-vs-offsite).
Additionally, on-site backup media can degrade over time if not properly maintained. Hard drives fail, backup tapes demagnetize, and other unforeseen issues can arise when relying solely on on-site backup solutions. Taking a hybrid approach with both on-site and off-site backups provides an additional layer of protection against site-specific catastrophes.
Cloud Backup Benefits
Cloud backup solutions offer a range of advantages over local on-site backups. Some key benefits include:
Accessibility – With cloud backup, data can be accessed from any internet-connected device, allowing users to recover files no matter where they are located. This makes cloud backups highly accessible in the event of an on-site disaster.
Scalability – Cloud backup services scale easily as data storage needs grow. There’s no need to purchase additional hardware, and capacity can be added or reduced on-demand.
Security – Reputable cloud backup providers offer advanced security protections like encryption, access controls, and data center physical security measures. For many businesses, cloud backups can provide enhanced security over local on-site options.
Cloud Backup Options
There are many popular cloud backup services to choose from, each with their own features and pricing. According to PC World, the top services in 2024 include Carbonite, IDrive, Backblaze, and Livedrive. https://www.pcworld.com/article/407149/online-cloud-backup-services-carbonite-idrive-backblaze-livedrive.html
Some key features to look for in a cloud backup service are unlimited storage, backup scheduling options, file versioning, and mobile apps for access. Pricing can range from free plans up to $10/month for individual use. For example, IDrive offers 5TB of storage for $79.50/year while Backblaze is $70/year for unlimited storage. Encryption, restoration, and sharing features should also be compared.
According to TechRadar, top picks for small businesses include Dropbox, Microsoft OneDrive, pCloud, and Backblaze. These services offer features like remote data wipe, permissions controls, and integration with common apps.

When evaluating cloud backup services, be sure to consider ease of use, security, customer support, and total cost of ownership along with features and capacity. Testing restoration and integrating with existing apps are also recommended during a trial period.
Physical Off-Site Options
There are several physical off-site backup options that involve storing backup data on external media and transporting it to another secure location for safekeeping:
- External hard drives or SSDs – Backup data can be copied to an external drive which is then stored off-site in a secure location like a bank safe deposit box. This provides a physical copy stored away from the primary location.
- Magnetic tapes – Tape drives and magnetic tapes are still commonly used for offline backups. Tapes can store large amounts of data and have a long shelf life. The tapes can be rotated off-site for secure storage.
- Optical discs – While less common today, optical discs like Blu-Ray can also be used to store backup data off-site.
When using physical media for off-site backups, considerations include data integrity, shelf life, transportation logistics, and physical security. Overall, external drives, tapes and optical media stored off-site provide an air-gapped, physical copy of backup data stored securely away from the primary location.
Hybrid Approaches
A hybrid backup approach combines both cloud storage and physical off-site backups for maximum flexibility and security. This hybrid model offers the convenience of cloud backups along with the air gap protection of storing backups offline (TechTarget). Key benefits of a hybrid approach include:
– Utilizing both local and cloud backup infrastructure – initial backups are stored locally, then incremental changes are sent to the cloud (Acronis).
– Providing faster restore times for recent backups stored locally, while maintaining off-site copies for disaster recovery.
– Giving users control over backup storage and data sovereignty with on-premises backups, while leveraging scalable and economical cloud storage.
– Offering multiple backup storage targets for redundancy in case of failure or outage of any one site or device.
The hybrid model offers robust data protection that is both convenient and secure. Organizations can tailor the approach based on their specific needs and priorities for backup and restoration.
Security Considerations
When choosing an off-site backup solution, security is a top priority. You’ll want to ensure your sensitive data remains protected both in transit to the backup location and at rest in storage. According to Offsite backups: Why they’re needed for disaster recovery, top security considerations include:
Encryption – Your backup data should be encrypted both during transmission and while at rest in the off-site location. Encryption protects your data from being read or accessed by unauthorized parties. Look for 256-bit AES encryption or higher for optimal security.
Authentication – Strict access controls, multifactor authentication, and role-based access should be implemented to control who can access and restore your backups. This ensures that only authorized personnel can retrieve your data.
Data privacy – Your off-site backup provider should have clear data privacy policies and retention procedures. Make sure they meet any regulatory compliance needs your business may have regarding data residency, cross-border data transfers, etc.
Proper encryption, access controls, and data privacy measures are crucial for keeping your off-site backups secure. Carefully evaluate potential providers on these factors before deciding on a solution.
Cost Analysis
The cost of backups depends on storage capacity, bandwidth, hardware and software costs. For on-site backups, there are upfront costs for backup storage devices or media and backup software licenses. Ongoing costs include maintenance, electricity, internet bandwidth and periodic replacement of storage media. According to Backblaze, on-site backup for a single computer with 5TB of data storage can cost around $1,027 for the first year and $127 per year after that.
In comparison, cloud backup services have lower startup costs because they utilize remote storage infrastructure. Backblaze estimates that 5TB of cloud backup for one computer costs around $60 for the first year and $120 per year after that. Cloudwards states that unlimited backup typically costs between $6-$10 per month, while multi-device plans average around $70 per year for 5TB. Factors like number of devices, storage space, bandwidth and features impact cost.
Some key considerations are balancing convenience and reliability versus expense, predicting capacity needs to control costs, and whether hybrid on-site plus cloud backup offers the right compromise.
Implementation Best Practices
Proper implementation of an off-site backup strategy requires following key best practices around testing, monitoring, and documentation:
Regularly test backups to ensure they can be successfully restored when needed. Test restores at least quarterly, if not monthly for mission critical data. Monitoring backup jobs for errors is also critical.
Use backup reporting to monitor the backup process. Alerts should be configured to notify if backups fail or have issues. Monitoring helps identify problems early.
Maintain thorough documentation covering the backup process, storage locations, restoration procedures, and testing results. This enables smooth restores when needed and helps new personnel manage the backups if there is turnover.
Following these best practices helps validate that off-site backups are working as intended and data can be recovered in the event of a disaster. They provide confidence in the backup strategy.
Conclusion
In conclusion, storing backups off-site provides critical protection against data loss from on-premise disasters. While cloud backups offer convenience, physical off-site options ensure total control over data security. Hybrid approaches that use both cloud and physical off-site storage provide the best of both worlds.
For most organizations, implementing a hybrid backup strategy with both cloud and physical off-site components is recommended. This balances security, recoverability, and cost-effectiveness. Regularly test restoring from backups and ensure proper encryption is in place. With the right strategy, off-site backups provide essential insurance against catastrophic data loss.
