What method do you use for backing up your files? How much does it cost? Do you deal with any security issues? How many computers do you have that are backed up by this method? Does it require maintenance of any kind? Are you (or someone at your company) IT-proficient enough to handle the maintenance?
We currently use a really janky/old school looking tape back up. We insert a new tape every morning. One tape is always kept off site in case of a physical disaster. Our tape deck/reader thing just kicked it, so I’m investigating alternative options.
