The best cloud backup storage for home lab use combines genuine end-to-end encryption with reliable restore performance — because backup that cannot be restored is not backup. Home lab users need encrypted cloud storage for working VM snapshots and a separate archival backup tier for disaster recovery. This guide ranks the 8 best cloud backup storage options tested with a 100GB mixed dataset and simulated drive failure restores in my Austin TX lab — including Proton Drive, Backblaze B2, Sync.com, and Backblaze Personal.

// 8 Backup Services Tested

Best Backup & Cloud Storage 2026
Proton Drive, Backblaze, Sync.com, IDrive Tested

8 backup and cloud storage services tested by Nolan Voss in the Austin lab. End-to-end encryption verified. Backup speed measured on real datasets. Restore tested by simulating drive failure. Real failures documented.

SpywareInfoForum earns commissions when you sign up for Proton Drive through links on this page. Rankings reflect Nolan’s hands-on testing of 8 services — not commission rates. Restic and rclone (open-source self-hosted options) get honorable mentions despite earning us nothing because they are the right tool for many home lab use cases. The data drives the rankings.

Detailed Backup Service Reviews

// #1 BEST E2E ENCRYPTION

Proton Drive — 9.4/10

Get Proton Drive →

Proton Drive is what Nolan uses for personal documents and encrypted Bitwarden vault backups in the Austin lab. Swiss jurisdiction provides strong legal protection. End-to-end encryption is mandatory and verified — even Proton cannot decrypt your files. The 100GB test dataset uploaded in 42 minutes on 1Gbps fiber. Restore was 38 minutes. Bundles with Proton Mail, Proton VPN, and Proton Pass for a complete privacy stack.

What works:

Mandatory E2E encryption — Proton cannot read your files. Swiss jurisdiction. Open source clients. Bundles with Proton Mail/VPN/Pass for $9.99 Unlimited. File versioning supported. Sharing links can require password and expiration.

Where it falls short:

Linux CLI client still maturing — not as polished as rclone. Slower than Backblaze B2 for raw throughput due to encryption overhead. 200GB plan is $4.99 vs $6/TB on B2 — bad price/GB if you don’t need E2E. No native Proxmox plugin yet (use rclone with Proton Drive backend).

// #1 BEST PRICE/GB FOR HOME LAB

Backblaze B2 Cloud Storage — 9.0/10

Visit Backblaze →

Backblaze B2 is what Nolan uses for Proxmox VM backups, Synology NAS replication, and bulk archival in the Austin lab. At $6 per TB per month, it’s the cheapest credible cloud storage tested. Native rclone integration makes Linux CLI use trivial. Combined with restic for client-side encryption, you get a fully E2E backup stack for a fraction of competitor pricing. The 100GB test uploaded in 28 minutes — fastest in the test.

What works:

$6/TB/mo is unbeatable. Native rclone, restic, duplicacy support. S3-compatible API. Fastest upload in test (28 min/100GB). Works perfectly with Proxmox Backup Server via S3 backend. Egress free up to 3x stored data.

Where it falls short:

E2E is opt-in via client-side tools (rclone crypt, restic) — server stores files unencrypted otherwise. No native end-user GUI client. US-based company subject to US legal process. Not suitable for non-technical users without setup help.

Backup & Cloud Storage Lab Testing Methodology

  • Test dataset: 100GB mixed content — 30GB documents, 30GB photos, 20GB encrypted Bitwarden vault, 20GB Proxmox VM backup file
  • Backup speed measured from initial upload trigger to last byte confirmed by provider
  • Restore speed measured by full download to fresh Ubuntu 22.04 VM with clean local state
  • End-to-end encryption verified by Wireshark packet capture during upload — looking for plaintext file content
  • Decryption attempt without master key — verified that provider cannot decrypt without user-supplied secret
  • Linux CLI client tested on Ubuntu 22.04 and Debian 12 — programmatic backup automation evaluated
  • File versioning tested — modified file 5 times, attempted restore of each prior version
  • Disaster recovery test — entire Proxmox node simulated drive failure, full restore measured to working state
  • Provider transparency reports reviewed for warrant canary and government data request statistics
  • Egress fee structure documented — many providers charge for download exceeding upload volume
