This is urgent. I need to back up all the links in five categories I have created so far. There are a total of 10,000 links. I looked into Links.pm file and there is no mention of 7 backups. I found 7 in nph-build.cgi. I looked into my backup directory, but found nothing there. I cannot afford to lose my links. What exactly do I need to back up and where are the files in backup directory?
