I first came into contact with computers in the 1960’s where they were used in 2 places where I worked, my only concern at the time was making sense of the output, these days I am equally concerned with the input and they no longer fill large air conditioned spaces.
I have for many years installed and maintained small file servers for offices, these offer secure file storage, a variety of methods of backups, and the possibility of secure remote access as well.
I also offer support for all desktop systems, especially if you are interested in migating from windows to linux or any other operating system, it’s a lot easier than you think. The compatibility problems that people complained about some years ago are now totally non-existant.
Dont hesitate to contact me if you have any problems.
