I have googled and searched, but can't find the command that 7zip command line utility uses for making incremental backups. So can someone please share the command ?

Thanks

btw I found this link: http://wmug.co.uk/wmug/b/sean/archive/2009/03/20/powershell-amp-7zip-incremental-backup-solution.aspx . But it seems to be for differential backups, even though it says incremental.

Should be simple, use this to create and incrementally update the archive:

7zr u -up0q3r2x2y2z1w2 {archive}.7z {path}

This page offers a reference for update options
