So, tools for previewing your files in the cloud are limited, and neither platform enables you to edit documents or images without downloading them. IDrive and Backblaze are both designed primarily as cloud storage platforms, not cloud-based productivity suites. However, you can pay extra to keep outdated file versions for one year or indefinitely. Even if you discard old versions, files are only truly deleted from IDrive when you empty out the built-in archive folder.īackblaze only keeps old file versions for 30 days. These files do count against your storage limit, so you have control over how many versions to keep and for how long. With IDrive, you can store up to 30 previous versions of a file for an unlimited amount of time. When it comes to file versioning, IDrive is much more robust than Backblaze. For files that you want to keep constantly synced across all your devices, IDrive offers a dedicated sync folder in your file explorer. You also get to set the schedule when these folders are backed up. One thing we like about both the IDrive and Backblaze backup clients is that you get to choose what folders to designate for upload to the cloud. IDrive offers a backup and sync app for desktop and mobile devices (Image credit: iDrive)
