| Having been a Network System admin, I was responsible for the backing-up of nearly 100 servers on our system. Here are a few tips that we followed that can prevent a disaster:
#1 - Have three copies of your data (not including your original)
#2 - Have the copies on at least two different media - eg. One local hard drive, plus one cloud - because there are times when the speed of a local back-up to recover from will save you from forcably removing massive quantities of your hair while waiting for a nameless/faceless techie from "Cloud-land" gets back from break to find and get your recovery files sent back to you. (Yes, some services are self-service)
#3 - Make sure at least one copy is off-site - you can't recover from a disaster of a fire, flood or tornado if your backup drive has gone off to see the Wizard with Dorothy & Toto.
#4 - If you're syncing data, make sure it's a one-way sync to the cloud, otherwise the cloud may see that you are suddenly missing a file or folder, and delete it on the cloud server as well.
We had a Legato system with clients installed on each server - not for the faint-of-heart. But we did have available from Legato a nice workflow for backing-up the servers.
Sunday was a full back-up of all servers, including the operating systems. Then Monday morning, I would collect those back-ups and walk them over to another building on campus for secured, off-site storage. I would also bring back to the server room the previous week's full back-up media for re-cycling in the media pool.
Monday thru Saturday, an "incremental" back-up was done - meaning only files that had been changed would be backed up.
The first of each month, a set of full back-up media was taken to the off-site storage, labeled and kept for a full year.
Hope this helps. | |

how do you backup all your important files?
