The short version

  • Each has a real cost: Cloudflare R2 there is no archive tier below Infrequent Access, so genuinely cold data costs roughly ten to fifteen times what it would cost in a deep archive class and there is nowhere cheaper to lifecycle it to.; IDrive e2 the included egress is capped as a multiple of stored data, so a small bucket that serves a lot of traffic exhausts the allowance quickly and the economics stop looking cheap exactly where a CDN backed store would still be free.
  • They diverge on capability: Cloudflare R2 covers Zero egress billing, IDrive e2 covers S3-compatible endpoints.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cloudflare R2

  • There is no archive tier below Infrequent Access, so genuinely cold data costs roughly ten to fifteen times what it would cost in a deep archive class and there is nowhere cheaper to lifecycle it to.
  • Class A operations are billed at 4.50 USD per million, so a workload that writes millions of small objects can spend more on operations than on the storage those objects occupy.
  • Infrequent Access carries both a retrieval fee and a thirty day minimum storage duration, so data that is deleted or re-read sooner ends up more expensive than if it had stayed on Standard.
  • You choose a location hint rather than a region, so you cannot prove to an auditor which datacentre holds an object unless you use a jurisdiction restricted bucket, and jurisdictions are limited.
  • Support level follows your Cloudflare account plan rather than the storage spend, so a team on a low tier account gets ticket support with no storage specific SLA, and an R2 incident is a Cloudflare incident you cannot fail over from because the free egress only exists inside Cloudflare.

IDrive e2

  • The included egress is capped as a multiple of stored data, so a small bucket that serves a lot of traffic exhausts the allowance quickly and the economics stop looking cheap exactly where a CDN backed store would still be free.
  • The region list is short compared with the hyperscalers, so data residency requirements outside the main markets are hard to satisfy and multi region designs have fewer options.
  • S3 compatibility covers the common calls but not the long tail, so software that relies on less common features can fail in ways that are hard to diagnose against a provider with thin public documentation.
  • Support is organised around a consumer and small business backup product rather than a platform engineering organisation, so escalating a storage layer problem takes longer than it would with a specialist provider.
  • IDrive publishes far less about the underlying architecture, durability engineering and incident history than its competitors, so due diligence on the storage layer is largely taking the vendor at its word.

Answered from the vendors’ own pages

Cloudflare R2: Is egress really free, with no hidden transfer charge?

Yes for data served out of R2 to the internet. You still pay per operation for the requests that serve it, and if you pull data into R2 from another provider you pay that provider the egress on the way in.

IDrive e2: Is the egress genuinely free?

It is included up to an allowance tied to how much you store, not unlimited. Read heavy workloads on a small bucket will exceed it.

Cloudflare R2: How does the total cost compare with S3 for a public download bucket?

Storage is more expensive per terabyte than S3 Infrequent Access, but S3 charges roughly 90 USD per terabyte served. Any bucket that serves more than about a fifth of its stored volume each month is cheaper on R2.

IDrive e2: Does it work with Veeam and restic?

Yes, both treat it as a standard S3 endpoint, and object lock is supported for immutable backup chains.

Cloudflare R2: Can I use R2 without using the rest of Cloudflare?

Yes, it works through the plain S3 API from anywhere. You lose the Worker binding and the free CDN caching in front of it, which is where a lot of the practical benefit sits.

IDrive e2: Is there a minimum retention period?

No fixed minimum retention charge on standard storage, which is a real difference from providers that bill ninety days on early deletion.

Cloudflare R2: Does R2 have a cold archive class like Glacier?

No. Infrequent Access is the coldest tier, at two thirds of the Standard rate plus retrieval fees.

IDrive e2: How does it compare with Backblaze B2?

The rates are close. B2 is the better documented and more widely integrated service; e2 is cheaper at list and has a different egress allowance model.
