However, I was somewhat disappointed to find that the -c option (to check the files against the watermark) is not recognised by the md5sum command, which makes it a bit useless, so is there a way around this, or is there a better way of achieving the same goal? I also found that there is no nohup command, which would have been useful when generating the md5sum file.

Anyway, I didn't want to just blindly backup possibly corrupt files, so I used md5sum on the Qmultimedia directory (find -type f | sed 's/./\\&/g' | xargs -r md5sum > Qmultimedia.md5, which took ages, as it contains around 1TB) with the aim of verifying the contents prior to backing up. Hello, I have a TS-119 with a 2TB disc whose main use is in storing CD's and DVD's, and since one DVD image mysteriously got corrupted, I purchased an external eSATA enclosure (by SumVision - only £12) and a 2TB HDD, which (after trimming the eSATA plug!) worked fine (though slowly - it took just over 7 hours to copy 1.1TB to NTFS using 3.2.5 Build 409T.
