USBFlashCopy backs up/synchronizes from external storage on the fly. It runs in the background and copies files from inserted media to a location on your hard drive. Useful for people who do much of their work on remote computers and need to automate the process of backing up their files. Supports unique profiles by drive serial number, drive letter policies, and speed controls.

Functional in 64-bit. Note that fully transparent operations (no user notification) are only available in the pro version.
