No. Sync storage keeps one folder identical on every device, so a deleted or ransomware-encrypted file is gone everywhere until you restore it from history. A backup copies your whole computer and keeps past versions for recovery.
Most services sold as cloud storage are really sync, including pCloud, Dropbox, OneDrive and Google Drive, while Backblaze and IDrive are true backup services that copy whole machines and keep their history. You often need one of each, and the US cybersecurity agency CISA’s ransomware guide recommends keeping offline, encrypted backups of critical data and testing them regularly.
Default to pCloud for sync. Its 2 TB plan costs $99.99 a year with no first-year discount to unwind, it runs on Windows, macOS and Linux, and you choose US or EU storage. Switch only when one applies.
Three years of list prices tell you more than one:
| Plan | Storage | 3-year cost | Per TB over 3 years |
|---|---|---|---|
| Backblaze | Unlimited, 1 computer | $297 | $59.40 at 5 TB |
| IDrive Personal | 5 TB | $323.64 | $64.73 |
| pCloud Premium Plus | 2 TB | $299.97 | $149.99 |
| Dropbox Plus | 2 TB | $359.64 | $179.82 |
| Proton Duo | 2 TB (2 users) | $539.64 | $269.82 |
Backup is cheapest per terabyte. That is all it does.
When your files fit in a free tier and you already keep a backup: Google gives every account 15 GB shared across Gmail, Photos and Drive, IDrive offers 10 GB for backup, and pCloud up to 10 GB. Don’t bother with terabytes for a few gigabytes of documents.
If you’ve already paid for Microsoft 365, you own OneDrive storage too: 1 TB on Personal, or 6 TB shared among six people on Family for $129.99. Don’t forget to check what you already pay for.
Three come up repeatedly: renewal prices that double, sync folders treated as backup, and the word “encrypted” read as “private”. Each one bites late.
Lifetime plans are a fourth, quieter trap. pCloud’s 2 TB lifetime plan costs $499, five years of its annual price, and only pays off if the company lasts. Most people forget that part. Keep a second copy elsewhere.
Every service gets a research score out of 10 from official pricing and terms, security research, incident reports and documented features. We don’t run speed tests. Affiliate commissions never change a score.
Privacy and encryption carry 25%, price and long-term value another 25%, versioning and recovery 20%, apps and sharing 20%, and company track record the last 10%. In practice the tie between pCloud and Proton Drive at 8.3 is broken by the unrounded score, so read the criterion notes for your own priority. Related: notes and docs apps and productivity.
Every product here is scored 0 to 10 on the same criteria, using published evidence. The overall score is the weighted average.
Backup services win. Over three years at list prices, Backblaze costs $59.40 per terabyte if you back up 5 TB from one computer, and IDrive Personal costs $64.73 per terabyte for 5 TB across unlimited devices. Among sync services, pCloud 2 TB works out to $149.99. Bigger plans cost less per terabyte.
Proton Drive and Sync.com encrypt every file end to end on every plan, and Icedrive includes client-side encryption on paid plans. pCloud sells encryption as a $49.99-a-year add-on. Dropbox, Google Drive and OneDrive personal plans lack it. The provider holds the keys.
Only when you plan to stay for years and accept the company risk. pCloud's 2 TB lifetime plan costs $499, equal to five years of its annual plan, and pCloud defines lifetime as 99 years or the account holder's life. Icedrive's costs $699. Don't trust any single provider with irreplaceable files.
When you delete a file on most personal plans, including pCloud, Dropbox and OneDrive, it stays recoverable for 30 days. Proton Drive keeps versions for up to 10 years on paid plans, Sync.com from 90 to 365 days, and Backblaze includes one year of version history at no extra cost.
If you've moved to Linux, pCloud, Dropbox and Icedrive have desktop sync apps, and IDrive covers Linux backups. Proton Drive offers only a command-line tool, Sync.com only WebDAV, and OneDrive and Google Drive have no official Linux desktop app. Backblaze Computer Backup does not support Linux.
