iDrive

About

IDrive backs up your Mac to secure off-site data centers over the internet, so a second copy of your files exists even if your computer is lost, stolen, or damaged. After the first full backup, it transfers only the changed portions of files, and Continuous Data Protection picks up edits between scheduled runs. One IDrive account can cover multiple devices, including Macs, Windows PCs, phones, and servers.

Unlike sync services that mirror your files, IDrive keeps history. It retains up to 30 previous versions of each backed-up file, and its Snapshots feature gives a point-in-time view of your account so you can roll back to a date before a problem such as ransomware. Restores can be done per file from a browser, by reverting to an earlier version, or by rebuilding an entire machine from a disk image. Files are protected with 256-bit AES encryption in transit and at rest, and with a private encryption key, only you can read your data.

The website's text does not specifically detail a Mac app's interface or Mac-only features, so this description reflects the Mac backup capabilities described on the site rather than app-specific details.
