Traditional Data Disaster Recovery
Your down time will vary, depending on your volume of data, level of warranty and a few other variables, but here’s a snapshot:
If you have an active, same day warranty with your hardware manufacturer, you could have a technician onsite, with parts, within 4 hours. Repair takes 2 to 4 hours, so your server – without any data or functionality – could be up in as little 6 hours. If you’re not covered under warranty, you can expect a new server in about 10 days.
If you choose to buy clone hardware, you could receive it within 48 hours of the disaster. This hardware is usually lower quality and won’t include drivers. Restoring these software drivers can take an additional 4 – 8 hours. That’s two days of downtime waiting for a replacement and an additional day for drivers. Then you…
Unpack the Server
A new server needs to be unboxed, racked, connected to the network and turned on. This takes about 2 hours.
Installing the Operating System
The operating system can be downloaded from Microsoft and installed on the server. Assuming the operating system has already been downloaded, installing it can take up to an hour, if all goes well.
The server’s data must be transferred from your backups and written onto the server. Depending on the hardware being used and the amount of data, this can take hours or days. A good rule of thumb is that for every hour needed to back up a server, 2 hours will be needed to restore it.
