I have a 3x system which is several years old and I'm nearly maxed out on the drive space. I use it for automatic off site backups every night. My work office data (Windows servers and PCs o/s) backups up over the Internet to a 3x appliance backup box that I have at my home office. It is my understanding that 3x is out of business and a different company took it over and came out with all new products so I cannot expand what I have.
I would entertain purchasing a new appliance (250GB minimum on the appliance) so I am open to recommendations regarding off-site backup appliance products.
As an alternative, a software solution is also of interest. I have read a little bit about windows software server backup solutions that can be loaded onto a pc at the home office and programmed to pull the data directly from my office systems. Years ago I had used Asigra which was way overkill (and too pricey) for my simple needs. I'm looking for something at the lower end of the price range. I have plenty of computers, so loading software onto a home PC to handle the backups is a viable solution. I would like some input as to any specific software suggestions and recommendations to handle this functionality.
Note: I will NOT entertain using any third party services (example: Carbonite) due to security compliance restrictions regarding the data --- so please do NOT offer suggestions on these kinds of third party services.
