Wasabi vs Sync.com: Which Should You Buy?

Let’s get one thing straight right out of the gate: comparing Wasabi and Sync.com is not an apples-to-apples comparison. If you’re coming at this from a home-lab perspective, you’re looking at two entirely different layers of your data stack. One is designed to be a backend target for your backup software; the other is a frontend replacement for your local file system.

I’ve spent years tweaking my offsite strategy, and the biggest mistake beginners make is treating “the cloud” as a monolith. You don’t just “put files in the cloud.” You either need an S3-compatible bucket to dump encrypted archives into, or you need a synchronized folder that keeps your laptop and desktop in parity.

Quick verdict

If you are confused about which one fits your current workflow, use this cheat sheet.

Spec-by-spec

When we strip away the marketing fluff, here is how these two services actually stack up based on their core offerings.

Feature	Wasabi	Sync.com
Category	Object Storage	Cloud Storage
Type	SaaS	SaaS
Pricing	$7/TB/mo	$8/mo
Primary Use Case	S3 backup	Encrypted cloud storage
Key Advantage	No egress or API fees	Zero-knowledge encryption
Main Trade-off	90-day minimum storage	Slower sync speeds

The “Infrastructure” Approach: Wasabi

For the home-labber, Wasabi is essentially a utility. It isn’t something you “log into” to browse your photos; it’s where your backup software (like Arq, Duplicati, or Kopia) sends data via the S3 protocol.

The real winner here is the cost structure. In the world of object storage, “egress fees”—the price you pay to get your own data back—are usually the hidden killer. Wasabi eliminates those egress and API fees, which makes it an ideal destination for long-term archives. However, there is a catch: the 90-day minimum storage requirement. If you delete a file after 30 days, you’re still paying for that space until day 90. This means Wasabi is built for archiving, not as a scratch disk for temporary files.

The “Privacy” Approach: Sync.com

On the flip side, Sync.com operates at the application level. You aren’t dealing with buckets or API keys; you’re dealing with folders and files.

The standout feature here is the zero-knowledge encryption. For those of us who don’t trust any provider with our raw data, this is non-negotiable. It ensures that only you hold the keys to your kingdom. The trade-off for this security architecture is performance; specifically, sync speeds are slower compared to other options on the market. If you’re moving a few documents and PDFs, you won’t notice it. If you’re trying to move terabytes of data daily, the lag will be apparent.

Pros & cons

Wasabi

Pros:

• Cost-Effective: At $7/TB/mo, it is highly competitive for bulk storage.
• No Hidden Fees: The lack of egress and API fees means your monthly bill is predictable.
• S3 Compatible: Works with almost every modern backup tool in the self-hosting ecosystem.

Cons:

• Retention Policy: The 90-day minimum storage can be a dealbreaker for users who rotate data frequently.

Sync.com

Pros:

• Privacy First: Zero-knowledge encryption provides peace of mind that the provider cannot access your files.
• Simplicity: Extremely easy to set up; no complex configuration required.

Cons:

• Performance: Slower sync speeds can be frustrating when dealing with large volumes of data.

Which should you buy?

The decision comes down to where this fits in your pipeline.

Choose Wasabi if you already have a backup strategy and just need a place for the data to live. If you’re running an automated backup script or using professional-grade backup software, Wasabi is the logical choice because it treats storage as a commodity without penalizing you for accessing your own data via egress fees.

Choose Sync.com if you want a “Dropbox alternative” that actually respects your privacy. If you don’t want to manage your own encryption keys or deal with S3 buckets, and you just want your files available across multiple devices securely, this is the way to go.

FAQ

What is the difference between Object Storage and Cloud Storage? Object storage (like Wasabi) stores data as objects in a flat hierarchy, making it ideal for massive amounts of unstructured data and backups via API. Cloud storage (like Sync.com) typically mimics a traditional file system with folders, designed for direct user interaction and synchronization across devices.

Does Wasabi charge to download my data? No, one of the primary advantages of Wasabi is that there are no egress fees for retrieving your data.

Is Sync.com secure for sensitive documents? Yes, it utilizes zero-knowledge encryption, meaning the service provider cannot decrypt or access your files.

What happens if I delete a file on Wasabi immediately after uploading it? Because of the 90-day minimum storage policy, you will still be charged for that storage space until the 90-day window has passed.

Our pick for personal cloud storage

Want privacy-first storage without recurring monthly fees? Consider pCloud — it’s EU/Swiss-based with optional zero-knowledge encryption and one-time lifetime plans, a strong value alternative for backing up your own data.
