OK, So obviously having asked the question I got further by examining the BACKUP manual in greater detail. It seems the command I need is: BACKUP/VERIFY/LOG DKA400:[*...] DSA3:[MEDIA.VAX_MEDIA.VAXBINDEC95...] The presence of the '*' in the input specifier causes the directory structure to be preserved in the output directory. *However* I still haven't solved the issue of timestamps. I'd like to preserve the original file timestamps, but whether I use this version of BACKUP or by saving to and then restoring from a SAVESET I still get modification times of the current date. Anyone know how to get round that issue? Cheers, Mark.
