I have used the command line version of Winzip for years in a batch file to do my backups. I only do them now every time I produce a Newsletter for my retirement association which is about four times a year. I did do it more often years ago but since apart from my own accounts and my son's there is little that changes very frequently and all the data (text and pics) is on separate partitions/drives, I tell myself that's enough. I have not been found out for many years. Touches wood!!!
