Yep I've been using it for the last 6 months. It works brilliantly. I have 2 VPS's here, and I use the script to backup data from one to another, with the backup split over 7 days, ie a certain number of accounts per day. I've also tweaked it so that once a week I do a full backup to the other server, so in effect I'm running full backup as well as incremental. It works great.
In fact there are a few of my replies in that thread, either under usename pmcwebs or petemartin, not sure who I was when I signed in to cpanel forums.
