Unix rsync is just fine, using an external usb drive.

It can be interrupted & restarted, it does not copy again files already
copied (default: check timestamp & size; checksum can be also used), and
you can browse with usual program the copy.
Many option also to handle cumulative backup.

My simple copy is : rsync -av /original/location/ /media/storage/usbdisk

No need to compress for a local transfer, and I often do not feel the
need for a checksum (but adding -c can be useful)

When rsync is not available, but ftp is, the clear winner is lftp.
But you have to be very careful about its tunning: a mirroring in the
wrong direction might quickly deletes a waste amount of data.
