What Backup do U use?

Generally, my preferred backup software for Windows NT or Novell Networks is Veritas BackupExec. I am a network consultant and have found it to be the easiest to setup and train others to monitor and use. Also it has add-on for backing up things like Exchange and SQL etc. It has Disaster Recovery add-ons that simplify that concern and it is fairly easy to get thru to a live person for tech support (Arcserve is really hard to get thru to tech support and is almost always a call back within 24-48 hours. It is also a resource hog on the server). BackupExec also has to ability to backup multiple servers from a single server remotely as well as backing up workstations remotely.
To make it short, I much prefer BackupExec and recommended it to most all of my clients.
