Server crash...Data corruption...Virus attack...Coffee spill over a laptop…Phone dropped down a sewer drain...
In the normal day-to-day, hopefully these won't be very common. In reality, the average organization will experience one of these more than twice a year, giving credence to the need for quality reliable backup or business continuity. But this post is not about what backup service to go with, instead what information you’ll need to help evaluate which solution will work best, thus making it easier to deploy.
Calculate Space Requirements Part 1Backup services are based in some way on the amount of space you require. Believe it or not this will be more than the sum of all the data your organization has. Some machines may need to be virtualized and you’ll need extra space to make that happen. Also, many backup services offer incremental backup, which is great, because it allows you to restore a past version of document and reduces the amount of full images you need to make saving time. Although increases the amount of space you need based on the amount of changes you need to capture. So, we’ll get back to this calculation in a moment. First we need to know what to add up together.
Identify image-level machinesAn image backup is a snapshot of an entire machine - settings, files, programs, registry, etc… Its really your bread and butter. An image allows you to restore files and even virtualize a machine so that users can access it even if the actual machine dies. Not every machine in your organization needs to be imaged, only those most critical machines.
Make a list of all the devices within your organization that require image backups and calculate the amount of space they require and move on to the next part.
