I understand that most folks who use FOG are operating in an environment using many many client computers and thus are interested in a fairly high performance FOG server to perform their tasks as efficiently as possible.
In today’s world home and small office systems are often in the half dozen or computer range but could benefit from a centralized backup system which FOG seems ideal for. A cron scheduled task might be used to call a script which would cause image uploads from the clients at regular intervals and maintain some fixed number of images for backup purposes.
A very inexpensive system might use USB hard drives for the repository and while their use would severely impact performance it would appear that they could be used, if one sacrifices speed. If one is willing to accept the speed reduction imposed by the use of USB hard drives then it would seem that the server need not be sophisticated either and thus even an arm processor system might be used as the FOG server.
I have built several LAMP stacks on pogoplug devices which can be bought for under $20 and when combined with a USB drive of suitable size seems like it should work as a minimal FOG server.
Has anyone ever tried this or is there something flawed in my thinking which would make this a very bad idea?
