What are the best IDrive alternatives?
The short answer
The main IDrive alternatives are Backblaze Personal Backup ($99 a year, unlimited data on one computer), Acronis True Image ($89.99 a year, 500 GB plus disk imaging) and Sync.com ($72 for the first year and $144 a year after that, 1 TB, zero-knowledge encryption). None of them matches IDrive's 5 TB across unlimited devices at $83.88 in year one.
In detail
People usually leave IDrive for one of three reasons: the interface feels dated, the first-year price renews at $119.88, or they want something other than a storage pool. Each of those complaints points at a different replacement, so start with the reason before you compare prices.
Backblaze Personal Backup is the swap for a single heavy machine: $99 a year, $8.25 a month, unlimited data with attached external drives included, and no storage math. The trade is coverage. One license covers one computer, there is no phone backup, and versions default to 30 days.
Acronis True Image suits people who want the whole disk, not just the files: $89.99 a year, $7.50 a month, full disk imaging, local plus cloud in one plan, and a layer that blocks processes touching your backup files. The catch is space: 500 GB of cloud.
Sync.com is the alternative for people who really wanted encrypted storage: $72 for the first year, $6 a month, then $144 a year, for 1 TB, zero-knowledge encryption on everything, and up to 180 days of version history on its larger plans. It syncs rather than backs up your machine, so it replaces IDrive only if sharing mattered more than restoring.
What none of them copies is IDrive's shape. One pool of storage covering unlimited PCs, Macs, phones and external drives, with up to 30 versions per file. If that is why you signed up, the honest answer is that renewing at $119.88 is still competitive.
Prices here are the annual plans on each provider's own pricing page, the same figures behind our Price Index, in US dollars. IDrive's $83.88 is a first-year rate that renews at $119.88, so compare year two before you switch.
