Manually backing up VMs is not just tedious—it’s risky. Human error can lead to missed backups, and that’s the last thing you need when your business relies on continuous operations. Automating your backup process ensures that everything happens on schedule without requiring constant oversight.
Full backups of large VMs can take up a lot of storage space and time. Instead of backing up the entire VM every time, use incremental backups, which only save the data that has changed since the last backup.
A snapshot captures the current state of your VM, including its memory, disk, and settings. If something goes wrong, you can revert to that specific snapshot, making recovery much quicker and easier.
It’s one thing to have backups, but it’s another to be sure that those backups will work when you need them. Regularly test your recovery process to ensure your backups are valid and your recovery methods work as expected.
Keeping all your backups on-site can be risky. If there’s a natural disaster, hardware failure, or even theft, both your live data and backups could be compromised. Storing your backups in the cloud gives you an added layer of security.
No matter where you store your backups—on-site or in the cloud—it’s important to encrypt them. Encryption ensures that even if someone gains access to your backups, they won’t be able to read the data without the decryption key.
Don’t just set up backups and forget about them. It’s important to monitor how your backup system is performing. Keep track of how long backups take, whether they complete successfully, and how much storage space you have left.
