working set (changed today method)

hi Guys,

before upgrading to backup exec 2012, I used to use working set (changed today method) for my CCTV server backup (working set has been retired in BE2012). Incremental is not really working well for me, since it's dependent to a full backup and I can't afford to run a recurring full backup. A full backup of the CCTV server takes up too much time (Terrabytes of backup).

any idea how I can do a backup of only everything that has been changed within the day files in be2012..?

thanks,
