Hi: I have an incremental backup system that runs every day, backing up any files modified in last day. However what I would like to do is, at the beginning of each month, copy absolutely everything from source to backup. Then increment from that. Thus at the start of each month I would have a 'full' backup. Ideally the full backup would run on a saturday so I envisage a line saying something like 'if today is saturday and not yet the 7th day of the month, backup everything, else backup incrementally'. I can do all the backup stuff, but stuck on 'day of month'. Can anybody help? Thanks!
