I am currently working as an IT manager for an Ag company. The former IT manager did not do any sort of backup of the servers other than specific folders to an online backup company. I am wanting to change this, running full backups once a week, with differentials every day after. I am wanting to know what options are out there. I am currently looking at tape backup, as well as external hard drives. I have 5 servers, 1 DC, 1 large App server (over 500 GB used at this moment), a couple of termservers, and a file server. Backing up to external drives would be cheaper, but I don't know the speed difference between the two options. Any other suggestions would be welcome.
Along with that, should I just use the standard Windows backup or should I go with a backup agent of some type? What are the pro's/con's? Thanks.
