Disk Imaging: a source or file where a copy of the entire contents or complete data of some kind is stored, like in these devices:
Hard drives
Flash drives
CDs
DVDs
Tape drives
Floppy disks
Disk images are used when it’s time to maintain the computer system and the company doesn’t want to lose it’s data in the process. A clone of the information is produced and kept safely in a storage file (as a disk image) until it’s time to re-install the information into the revamped or new computers.
Simplify With Imaging Software and Deployment Appliance
This is especially helpful when the business has several computers networked together and they’re updating or replacing them all. There are many tasks to be done manually before and after the re-install. These tasks being done manually on many computers opens a good chance for human error to occur, and that chance multiplies with each consecutive computer being manually updated.
Both the before and after tasks are also time consuming and it slows the process that’s only partially automated. Thankfully, there is software called a deployment appliance that performs these before and after tasks for the company and makes the whole process swift and cohesive. The process can also be a lot easier with good imaging software.
The software does as it’s programmed to do, so there’s nothing forgotten or overlooked; no files to break or get lost, no miscalculations or errors to deal with. Plus, it’s cost effective; when a business considers paying the wage of people to transfer the data manually, the price of the reusable storage device and the software pay for themselves.
