Backing up Data

Am backing up my data to a memory stick. Many years ago I think I wrote a small dos program to identify files that had been modified by their attributes and overwriting only those files that had changed rather than overwriting the whole lot.
But as age takes over cannot remember. Or should I be using a windows type backup programme.

Regards Cliff

The XCOPY command is very handy and it may do all you want. The /M parameter copies only the files which have the archive attribute on and turns it off.

Karen Kenworthy's "Replicator" is very hard to beat and it is free.

Another great program is Robocopy and does exactly what you want to do. This comes with Windows 2K and XP on the resource disk. I think you maybe able to find it else where. I use it to run backups like you want to in only copying files that have changed. It is much like xcopy but as the name stated more robust. There are a lot of switches that can be added.
