USBFlashCopy 1.16

Fast backup utility for storage cards, USB flash drives and other removable media. Simply plug in the media and use it as usual, USB Flash Copy automatically backups your data in the background.
You can set up profiles for particular medias in order to back up them with custom settings (e.g. copy speed, file filters, destination path). Drives with no profiles are copied with default settings which include separate folders named after drive's serial number, normal copy speed and no filters.

Other options allow to disable driver letters from being watched, force drives to be copied even if they are not removable (network drives).
