Using USB Memory Sticks to backup

I'm trying to set up a RELIABLE backup routine using several USB memory sticks on a SCO 6 Server.

Does anybody have any experience of how to do this? I presume I have to mount the memory stick, copy the files to it & then unmount the stick so that another memory stick could be used for the next backup. Or is there an easy routine to set up to do incremental backups to the same memory stick?

I've had a go at doing this but my server seems to 'freeze' for a long time while copying the files - I would have expected this routine to be very quick because it has no 'mechanical access' at all and just relies on the 'electronics'.

Another problem I've had is that if the memory sticks are not mounted and unmounted correctly the copied file structure becomes corrupt with 'phantom' directories of files etc. and access problems to the memory stick - anybody else any experience of this and how to overcome it?

If anybody has written a routine from the # prompt and is willing to share I would gratefully receive!

Thanks in anticipation!

     ernet and Message Transfer Protocol.  USB templates are currently selected using the "hw.usb.template" sysctl.  The "hw.usb.template" value
     can be changed at any time, but will not have any effect until the USB device has been re-enumerated.
