Backup Features:  

IDrive provides exceptional backup tools; in fact they offer almost everything we were looking for in an online backup service. This service is extremely easy to use and provides backup scheduling by the day, week, time and month. It also includes the ability to set bandwidth usage and you can enable open file backup which will backup open files of Outlook, QuickBooks, Excel, Quicken and more.

It also provides some advanced versioning tools. This service will save up to 30 versions of a file and will save files deleted from the local drive for 30 days; so if you accidentally delete a file, you can restore it easily with IDrive.

This service provides continuous backup and can be configured to backup changes in files as often as every 10 minutes. IDrive can also backup mapped drives such as from external drives that are connected to your computer. You can even restore from a specific time frame and not just from the most recent backup.

With the IDrive Pro version users get the additional ability of being able to manage multiple accounts through a single account. In addition, you can set it up to work through a connection via a proxy network connection.

Remote/ Mobile/ Web Access:  

With IDrive you can view and manage your files from any computer with Internet access. However, like many services you cannot restore or sync to a second computer without a second IDrive account. They do not offer cell phone specific tools and we would like to see them add more file sharing and large file sharing tools.

Security:  

IDrive uses 128-bit SSL encryption for transfers and 256-bit AES encryption for storage with a user defined key. This is more than adequate transfer and storage encryption for your data. We did not see that they offer geo-redundant storage.
