IBackup’s and IDrive’s business tiers are almost identical feature-wise, except IDrive doesn’t support the creation of multiple backup sets and sub accounts are handled a little differently.

Business tiers start out at $99.50 (GBP 65.32) per year for 250GB (also subject to discounts), but you can get a better deal from IBackup, which offers 500GB for the same price. 1TB of personal space costs $59.50 (GBP 39.06) per year, but can be cheaper if you wait for discounts on first year. Update, August 2016: IDrive are running a 75% of deal for their 1TB plan here, bringing it down to $17.38 for the year, it’s worth snapping this up while it’s still available. That includes PCs, Macs, iPhones, iPads, Android devices, Linux PCs, and Windows Phones.

No credit card required, the free version nets you 5GB of backup space, all of which can be synchronized across as many devices as you can fit into that space. To start off, IDrive offers what may be the best free tier available for individual users. So well, in fact, we’re not even sure why Pro Softnet bothers making two separate products. We liked the business-centric IBackup in our review, so how does its sister service stack up? Quite well.

IDrive is the consumer-targeted online backup solution from Pro Softnet, the same company that makes IBackup.
