When a Las Vegas business owner asks us “should I back up to the cloud or to a local device?” our answer is almost always the same: you need both, and here is why.

Cloud backup and local backup are not competing options. They protect against different risks. A business that only has cloud backup is vulnerable to one set of problems. A business that only has local backup is vulnerable to a different set. A business that has both is protected against nearly everything.

What Local Backup Is Good At

Local backup means storing copies of your data on a physical device in your office — a NAS (network-attached storage), an external hard drive, or a dedicated backup appliance. The data stays in your building, on your network.

Speed of recovery. This is the biggest advantage of local backup. If your server goes down and you need to restore 500GB of data, doing it from a device on your local network takes minutes to hours. Doing it from the cloud over your internet connection could take days. For businesses that cannot afford extended downtime, local backup dramatically reduces recovery time.

No internet dependency. Local backup works even if your internet is down. If your ISP has an outage and you simultaneously need to restore data (unlikely but not impossible), local backup is accessible. Cloud backup is not.

Lower ongoing cost for large data volumes. If your business has terabytes of data, local backup storage is often cheaper than cloud storage at that scale. You buy the hardware once and use it for years, versus paying monthly per-gigabyte cloud storage fees.

What Local Backup Cannot Protect Against

Local backup has one critical weakness: it is in the same physical location as your production data. If something destroys your office, it destroys your backup too.

• Fire or flood — a fire that destroys your server room also destroys the backup device sitting next to it.
• Theft — a break-in that takes your servers could also take your backup device.
• Ransomware — modern ransomware specifically targets backup devices on the local network. If your backup NAS is accessible from the same network as your workstations, ransomware that encrypts your servers will also encrypt your backups. This is the most common way businesses lose both their production data AND their backup simultaneously.

What Cloud Backup Is Good At

Cloud backup stores copies of your data in a secure data center operated by a backup provider. The data leaves your building entirely and is stored in a geographically separate location.

Protection against physical disasters. If your office is destroyed by fire, flood, theft, or any other physical event, your cloud backup is completely unaffected. Your data is safe in a data center hundreds or thousands of miles away.

Ransomware resilience. Cloud backup solutions designed for business use feature immutable storage — meaning once data is written to the backup, it cannot be modified or deleted by ransomware, even if an attacker gains access to your network. This is the single most important defense against ransomware destroying your backups.

No hardware to maintain. There is no physical device in your office to manage, monitor, or replace when it fails. The backup provider handles all of the infrastructure. For businesses without dedicated IT staff, this simplicity has real value.

Automatic offsite compliance. Many compliance frameworks (HIPAA, PCI, CMMC) require offsite backup as part of a data protection plan. Cloud backup automatically satisfies this requirement without you needing to physically transport backup media to another location.

What Cloud Backup Cannot Do As Well

Speed of recovery for large restores. If you need to restore an entire server from cloud backup, you are limited by your internet bandwidth. Restoring 500GB over a 100Mbps connection takes roughly 11 hours — and that assumes your full bandwidth is dedicated to the restore (it will not be if your team is also working). Local backup can do the same restore in under an hour over your gigabit local network.

Ongoing cost for large data volumes. Cloud storage is priced per gigabyte per month. For businesses with multiple terabytes of data, cloud backup costs can add up. The economics favor cloud for smaller data sets and local for very large ones.

The Right Answer for Most Businesses: Both

The industry standard approach is the 3-2-1 backup rule:

• 3 copies of your data (the original plus two backups)
• 2 different types of storage media (local device plus cloud)
• 1 copy offsite (cloud backup satisfies this)

With this approach, you get the best of both worlds: fast recovery from local backup for day-to-day issues (accidental deletions, hardware failures, application problems) and bulletproof protection from cloud backup for catastrophic scenarios (ransomware, fire, flood, theft).

For businesses that run primarily on Microsoft 365 and do not have on-premises servers, the equation shifts toward cloud-only backup — because your production data is already in the cloud. In that case, a third-party M365 backup solution that stores data independently from Microsoft’s infrastructure may be sufficient. But for any business with on-premises servers, NAS devices, or local applications, local backup remains an important component of the strategy.

What to Look for in a Backup Solution

Whether you choose cloud, local, or both, the backup solution should include:

• Automated scheduling — backups should run automatically without anyone having to remember to start them.
• Monitoring and alerting — if a backup fails, someone should be notified immediately. A backup that has been failing silently for three months is not a backup.
• Regular testing — a backup you have never tested is a backup you cannot trust. Recovery should be tested periodically to confirm the data is actually restorable.
• Encryption — both in transit and at rest. Your backup data should be encrypted so it is protected even if the storage medium is compromised.
• Immutable storage — for cloud backups, immutable storage prevents ransomware or attackers from modifying or deleting your backup data. This is non-negotiable in 2026.
• Defined RTO and RPO — you should know how quickly you can recover (RTO) and how much data you could lose in a worst case (RPO) before a disaster happens, not during one.
