Why Backup Windows Server to USB Drive?

As we all know that creating Windows Server 2012 backup is very essential. If any emergency happens like hard failure, system crash, you can restore system and disk to its previous state and do not need to worry about data loss. Besides, choosing a safe place to store system image backup is even more critical. There are so many destination places to choose from. You can backup system image to NAS, local drive, CD/DVD, etc.

Think about this: if you save your backup to the internal hard drive, you may risk losing all the backups if the hard drive failure occurs. Also, backing up to NAS is not safe too. It may be infected by malware and virus if the shared location is always connected. 

Considering all factors, it’s a safe and reliable way to backup Windows Server 2012 to external hard drives like USB flash drive. There are many advantages to backup to USB drive.

  • First and foremost, as USB drive is separate from computer, once the backup is done, your data is safe from hard failures, virus and malware.

  • Almost all computers have USB ports. It is also very common on other devices such as pads and video game consoles. You can connect a USB drive to different devices very easily.

  • USB drive is small and portable. You can carry it easily in a corner of your pockets.

Then, how to create Windows Server 2012 (R2) backup to external hard drive? Two ways will be described in the following.

Method 1. Create Windows Server 2012 Backup to USB Drive with Windows Server Backup

Microsoft offers Windows Server Backup (WSB) to help users backup their server data. It is not difficult to use. However, Windows Server Backup has default limitations.

◈ The unused space of USB must be equal to or more than 64GB. Otherwise, you cannot find your USB drive at local drive. It is a default limitation of Windows Server. Here I recommend using a 128GB USB drive (The bigger, the better).
◈ Basically, Windows backup has no compassion. If you set a scheduled backup, the backup disk is very easy to become full.

If you are OK with these issues, try the following steps to backup Server 2012 to a USB drive. If you want a backup tool without limitation for free storage space on the USB drive, go to Method 2 to learn more.

Step 1. Press Win + R and type “wbadmin.msc” to open Windows Server Backup. Or you can open it by clicking Start and selecting Administrative Tools. Find Windows Server Backup and click it. Install Windows Server Backup first if you did not install it.
