Hi Fantismo,
Like you, I am am IT manager with a set of responsibilities, one of which was to ensure that all my users adhere to a strict backup policy of all company data. Problem being that we run a virtual office with users having home pc's & laptops along with a central server room with multiple W2k servers. As you can imagine, quite a headache to manage the backups. We looked at a couple of solutions, mainly Veritas and Attix5 (did not try Connected as they seemed a little vague on a server offering). It was not really a contest as the Veritas solutions were much more expensive and not as quick. we now have laptops, dasktops & servers backing up to a central server with a further mirror server at another site. We still perform tape backups as well, but they have not been accessed for ages (by the way, as the user can access their own Attix5 backups to perform a restore, it have cut down the technical support time by not having to retrieve files from a tape based system)
In response to your last question, we now resell the product ourselves to our customers. This is as a result of interest in the Attix5 solution and increasing use of ADSL by many more companies. I can arrange a trial for you to make you own mind up, if you like. ;-)
