Xdrive entered the market in 1999 and acquired the popular FreeDrive service in 2002, gaining a large customer base. Despite its age (the backup process is executed in a DOS window), the code is still effective and permits command line control. The default doesn't use SSL encryption, but it can be enabled with a checkbox. Both the Web browser and client applications permit encrypted data transmission for backups and restores, but only the client version allows scheduled backups. We found the Web interface a bit sluggish, temperamental, and at times unresponsive. (Xdrive has a beta client that should improve performance.) Restore operations via the client requires users to access the online drive from within Windows Explorer and copy files. You can manage folder permissions via the Web interface, and you can send a URL to multiple people permitting them access to folders you specify as public. Data on the server is not encrypted.
