Do you want just one file with just the changed files added? Or do you want a new file to be saved? I've used Linux for years but I'm still a newbie, I wrote a script to save 3 very important files and send them to my ISP disk space, if we had a fire the backup tape would be useless. I used the system date when I name the backup file so I have a separate copy of the files, they are encrypted also, then sent by ftp. I spent hours and hours on a simple script because I didn't know how to get it to do the things I needed and had to look everything up. If you want a copy of the script send an email to my office: sales@xxxxxxxxx and I will forward it to you. In fact I just got an email from my ISP: Hello Your disk usage on the server is over its limit. So now it's time to clean out my old files. Tim...
