The initial setup was supposed to be complex, and a guy from Atempto went to our site and they did it with us together. So, in the end, it was quite clear and straightforward. The deployment took one day. From time to time, we require maintenance. Most things can be done also automatically. We prefer to do some manually like recycling virtual cartridges. Two people are required for maintenance. Two people use it daily. Time Navigator runs daily, for some backups, even more, three, four times a day, for critical stuff. But for intervention, we have two, three per week.
