What does it take to get PC or server backups to work properly and bring computers back to operational status? maybe simply Image backups
Correctly stored data files are a critical component for most organisations.
However, on their own they won’t let you get back to business. You’ll also need the applications that generated those data files and you’ll need the associated configuration and profile information.
That includes user and account-specific information and any purpose-built software modules to link your system to others in your enterprise. The smart solution would be to back up all of this information within the same process.
That in a nutshell is the promise of the disk image backup. Instead of sifting through directories and files to pick out the ones you think you really need, you take everything. You get an exact copy of what is on the disk.
Subsequently, you can then copy that image back from backup medium onto the original disk. Your PC or server then boots up using that image. You get a system that looks exactly like it did when you made the image backup.
How often should you make such image backups? That will depend on a number of factors. Firstly, there is the amount of backup storage space you have.
Secondly, your RPO or recovery point objective will set a limit on the maximum time between each successive disk image backup.
Thirdly, your disk image backup solution may be smart enough to save backup storage space by only backing up the parts that have changed, rather than the whole disk image every time. RTO (recovery time objective) should be less of an issue however.
Disk image restore is often a matter of minutes, rather than hours. Nevertheless, as ever, test your restore procedure before you actually need it, to make sure it reliably gives you a working up to date system again.
