Note that it is common for centrally-managed servers to have tape backup systems that automatically backup new files. Files may well be classed as new if they are renamed or moved. Therefore it is good practice to copy files to what can reasonably be considered a final location on the server. In other words, don't make a habit of placing files in a temporary location on the server then moving them. Try to avoid a future situation where very large directories need to be moved or renamed.
