The most features for your money — back up every device you own under one account, with proper versioning and even server support.
Best for: Households & small businesses. Price: ~£3–£8/mo, multi-device.
If Backblaze is the calm minimalist, IDrive is the Swiss Army knife. One account backs up your laptop, your partner’s laptop, the phones, and — unusually at this price — a NAS or server too.
Versioning, snapshots, disk-image backup, and genuine multi-device coverage under a single storage pool. The first-year pricing is often startlingly cheap.
Storage is capped rather than unlimited, the interface throws a lot at you, and the renewal price steps up after the introductory year. Worth diarising.
Anyone with several devices, or a small business that wants one tool to cover laptops, phones and a server.
People who want the absolute simplest possible option — Backblaze is calmer.
