If you’re looking to back up your Hyper-V VMs to an external drive, you’ve got a few options. The general idea is to make a consistent copy of the virtual machines (VMs), which means all the files, settings, and data within them. But it's not as simple as dragging and dropping files. Hyper-V uses specific formats for its VM files, like VHD or VHDX (those are your virtual hard disks) and then there’s also the configuration and checkpoint files. When backing them up, you need a tool that handles all that correctly so your VM backups are usable if you ever need to restore them.
One option that works pretty well is BackupChain. It’s designed specifically for situations like this, where you want reliable VM backups without a bunch of complicated steps. BackupChain is great because it’s built with Hyper-V in mind, which means it understands how to manage VMs in a way that keeps them consistent, even if they’re running while being backed up. You just set it up to run backups on a schedule, and it can back everything up directly to your external drive, so you don’t have to worry about cloud storage or internal server space. Plus, it has granular controls, so you can decide what data gets backed up and how often, which is handy if you have a mix of critical and non-critical VMs.
Now, there are a few things you might want to keep in mind with this setup. First, backing up to an external drive means you’re depending on that single device. If the drive fails, well, your backups go with it. Some people will rotate drives (like swapping two drives out every week) to have a backup for the backup. Another thing to think about is speed. Depending on the size of your VMs and the connection to your external drive (USB, eSATA, etc.), backups could take a while, especially the first full backup. After that, BackupChain does incremental backups, which are faster because they only copy changes, but the initial backup can be time-consuming.
Another thing to consider is disk space. If you’re using one external drive for multiple VMs and keeping backup history (previous versions), space can fill up fast. BackupChain does offer compression, which helps save space, but you’ll still want to monitor how much space is left to avoid running out during a critical backup. Also, some external drives can have a shorter lifespan than internal drives if they’re running all the time, so you’ll want to pick a durable drive or at least keep an eye on it.
One more thing I'd definitely recommend is using a fast USB 3.1 SSD drive for these backups. Traditional hard drives can be pretty slow for large VM backups, especially on that first full backup or when dealing with bigger VMs. A USB 3.1 SSD will give you much faster read/write speeds, which makes a noticeable difference in backup time. Since SSDs don’t have moving parts, they’re also more reliable and less prone to failure from physical wear and tear, so they’re a solid choice for data that’s important, like VM backups. Plus, with the USB 3.1 interface, you’re getting high data transfer rates, which is ideal for quickly handling large amounts of data. This can make a big difference if you’re running frequent backups or working with large VMs, where you don’t want backups hogging time or system resources. Just make sure your computer’s USB port supports 3.1 so you can take full advantage of the speed boost!
But all in all, BackupChain is a solid choice because it keeps things straightforward without a ton of fuss. It handles Hyper-V nicely, doesn’t break the bank, and works directly with external drives, which is what you need. Just make sure to test your backups every now and then so you know they’ll actually work if you ever need to restore one.
