Online Backup vs. External Hard Drives – Pros & Cons to Each
The convenience and simplicity of cloud-based backup can look very attractive to organizations grappling with data redundancy challenges. That said, there are instances where external hard drives can make more sense. To cultivate a safe, effective backup strategy, consider the pros and cons of each storage option.
Online Backup
Cloud-based backup can be a convenient, cost-effective solution for organizations in search of automatic redundancies.
Advantages
- Online backup can be set to consistently occur without the need for much – if any – intervention.
- When files are stored on a remote cloud-based storage service, they are available anywhere, anytime via the Internet.
- Most providers copy data across multiple locations, providing effective redundancies in case one data center goes up in flames.
- A great solution for budget-strapped organizations, cloud storage is both scalable and affordable.
Disadvantages
- Some cloud-based storage services utilize bandwidth throttling, which can drastically slow data upload speeds.
- Not all cloud storage providers offer adequate security for sensitive files.
- Some providers implement storage and bandwidth caps, complete with hefty overage charges.
- Without Internet service, you cannot access any data.
External Hard Drives
While not always as convenient as online backup, external drives do have some advantages that make them especially valuable.
Advantages
- External drives are relatively cost-effective, depending on an organization’s needs.
- Data upload speeds are generally much faster than those of cloud storage.
- External drives offer good portability and can be taken off-site when appropriate.
- Since you maintain control over security, external hard drives are less vulnerable to hackers and inadvertent file sharing.
Disadvantages
- Like any physical device, external drives can be lost, stolen or damaged.
- It can be impractical to consistently update and store external drives off-site.
- Although they can be made especially secure, you are responsible for taking the lead in this department.
- Data cannot be accessed from anywhere outside of your organization’s local network
Making a Complete Choice
Every individual organization has unique needs that can make online backup more appropriate than external hard drives, and vice versa. In the vast majority of cases, however, a combination of the two provides a more complete backup strategy, especially for organizations that deal with sensitive information.
