Backblaze vs IDrive Inc.

What Backblaze is

Backblaze sells distinct products, most notably B2 Cloud Storage and Computer Backup. B2 is usage-billed always-hot object storage with Native and S3-compatible APIs, browser access and command-line tooling. Current public pricing starts with 10 GB free, then meters byte-hour storage, egress beyond an allowance and selected Class D transactions. Encryption, Object Lock, version history and replication are capabilities to configure—not substitutes for independent access controls and tested recovery.

What IDrive Inc. is

IDrive is a proprietary backup service for computers, mobile devices, external drives, NAS and business systems. Its current Personal monthly plan is $11.99 for 5 TB, while Basic provides 10 GB without a credit card; annual and two-year discounts apply only to the first year before standard pricing. Backup, Cloud Drive synchronization and IDrive e2 object storage are distinct services. IDrive retains up to 30 prior file versions and offers an optional user-defined encryption key, but losing that private key makes restoration impossible. Storage overages are separately chargeable.

What Backblaze is built to do

S3-compatible API

Supports common S3 operations alongside Backblaze's Native API.

Usage-based storage

Bills stored bytes over time with separate egress and selected transaction rules.

Object immutability

Object Lock and Legal Hold can prevent deletion or change for governed retention periods.

Encryption and replication

Offers managed-key or customer-key SSE and configurable bucket replication.

What IDrive Inc. is built to do

Device backup

Protects supported PCs, Macs, Linux systems, phones, tablets, external drives and NAS devices by plan.

Snapshots and versions

Maintains historical views and up to 30 previous versions of backed-up files.

Private-key encryption

Offers AES-256 client-side protection with a user-defined key not stored by IDrive.

IDrive Express

Uses shipped physical storage for eligible bulk backup seeding and retrieval workflows.

Choose Backblaze if

• Backup repositories whose software has verified B2 or S3-compatible support
• Media and application objects with modeled storage, download and transaction patterns
• Immutable off-site copies configured with restricted keys, Object Lock and restore drills

Skip Backblaze if

• The workload depends on an untested Amazon S3 feature or exact behavioral parity
• Required data residency, region pairing or recovery throughput is not available and verified
• No owner exists for key rotation, retention, lifecycle, replication and restore testing

Choose IDrive Inc. if

• Households or professionals backing up several computers and mobile devices under one account
• Small teams protecting endpoints, selected servers or NAS appliances within a known capacity
• Users who can securely escrow a private encryption key and regularly test representative restores

Skip IDrive Inc. if

• The requirement is primary application hosting or S3-compatible object storage rather than endpoint backup
• Data growth cannot be constrained and per-GB overage has not been budgeted
• No process exists to preserve the private key, backup configuration and independent recovery evidence

Backblaze: pros & cons

• Low-friction object storage: Native and S3-compatible APIs work with many existing backup and application tools.
• Published usage model: Storage, egress allowance, overage and transaction classes are documented publicly.
• Data-protection controls: Optional server-side encryption, Object Lock, version history and bucket replication support resilient designs.
• Egress options: Downloads are free up to three times average monthly storage and through named CDN/compute partners.
• Not all S3 behavior is identical: Compatibility must be checked against the exact SDK, operation and application workflow.
• Encryption is a configuration decision: Official documentation says B2 data is not encrypted by default and offers optional SSE.
• Recovery cost can vary: Large restores may exceed free egress and generate transaction, network and operational costs.
• Product confusion risk: Computer Backup retention and device rules do not describe generic B2 object storage.

IDrive Inc.: pros & cons

• Multi-device coverage: One account can protect supported desktop, mobile, external-drive and NAS data.
• Historical recovery: Snapshots and up to 30 prior file versions provide point-in-time options against mistakes or ransomware.
• Optional private key: Client-selected encryption can keep the decryption key off IDrive servers.
• Physical transfer option: IDrive Express can seed or retrieve large backups without consuming normal internet bandwidth.
• Discounts expire: Annual and two-year promotional rates revert to standard pricing after the first year.
• Overage can be expensive: Personal and business-family plans publish per-GB monthly charges above quota.
• Private-key loss is terminal: IDrive cannot decrypt private-key backups if the customer loses the key.
• Product names can confuse: Backup, Cloud Drive sync, application backup and e2 object storage have different activation and billing.
