Why Offsite Image Based Back Up is Worth It
Back up is your best friend when proverbial @#$% hits the fan. Notice the use of the word ‘when’ because it’s rarely ‘if’. With employees clicking on links/attachments they shouldn’t, hackers using brute force or clever social engineering it is very difficult to control the security of your network. That’s why secure and reliable data back up is critical to your business.
At AbleIT our best practice is to have data back up onsite & offsite and to use an image based back up vs. a file based backup. Here’s what all this means; onsite means you back up your data to an onsite storage device often called a NAS (this is often done automatically set to a reoccurring time, every day). The onsite version should be your first go to for recovering data, it will be the fastest. However, fire, flood, theft or possible corruption can make this local data unavailable. That is why we recommend offsite back up. Back in the day the industry used tapes for back up and best practice was to create a tape back up and carry it to an offsite location. However, as tech advances we can now use replication software and automatically back up and transfer the data to cloud based servers offsite with second locations as another redundancy. Without getting too technical, what is the difference between file based and image based backup? File based back up is a back up at the file level whereas an image based back up takes a snapshot of the server data and set up (typically called a virtual machine or VM).
So what’s the value of an image based back up? The recovery time is way faster because we don’t have to rebuild as much. Potential down time can go from a couple weeks to an afternoon.
