#!/bin/sh tar clfCS - $1 --atime-preserve --exclude TRANS.TBL . | tar xpfC - $2 I don't recall why I selected each of those options and some may be quite inappropriate (e.g. excluding TRANS.TBL is for copying Rock Ridge CDs), but --atime-preserve is a must, or suddenly all your files will be stamped as accessed today, which confuses programs like mutt. S and p are necessary to preserve sparse files and permissions. l prevents tar from including /mnt itself. The message you are getting probably means that you have a file on your disk dated into the future, try locating it with # tar clfCS - / --atime-preserve . | tar tvf 2>&1 | less -j2 then hit : /future timestamp<enter> to find the file with the possible error and check its actual status with : !stat /path/filename and check that tar did not throw it away with : !stat /mnt/path/filename Anyway, the message should not prevent tar from doing its job. My personal cure after checking that it is harmless would be # (tar options | tar options) 2>&1 | fgrep -v "tar: Archive contains future timestamp" A more rude trick is to stop all other processes (especially cron and ntpd), use date to set your clock 5 years into the future, copy the files and set the clock back. -- This message is hastily written, please ignore any unpleasant wordings, do not consider it a binding commitment, even if its phrasing may indicate so.
