The only problem with Active Backup for Business is its name. I use it on my home network to backup all of our desktop PC's and laptops. Its brilliant. Easy to setup and easy to schedule for those computers that are typically running all day, most days of the week. For the occasional backup for seldom used computers, the manual backup is also dead easy. For your client, I would also have a Synology off site to backup the main NAS. Be sure to check in on ABB occasionally to ensure that backups are actually occurring. Not that I have ever had one missed unless it was offline.
Avi! I LOVED THIS VIDEO! So well done and real world which gives it total validity. ABB is an awesome tool. I use it in my home to backup all my computers, NAS devices and with my clients as well. Absolutely, loved watching you smash the hard drive to ground. Laughed out loud on that one. Great way to show proof of concept and entertaining as hell. Awesome!
