How to Use ZFS Snapshots and Clones
How to Use ZFS Snapshots and Clones. If you’ve decided to use ZFS on your storage devices, congratulations! You’re using one of the most complex and feature-rich filesystems on the planet. And if you ever decide to store long-term data, such as family photos and videos, seriously consider ZFS. In a redundant setup, such as four mirrored hard drives, it absolutely guarantees you will never lose one bit of data due to bit rot or other forms of storage degradation over time, computer errors and so on. ZFS can self heal and recover data automatically. Complex algorithms, hashes and Merkle trees guarantee data integrity. However, in this tutorial why ZFS is the best choice for archiving long-term data is not covered. Instead, what snapshots and clones can do for you is being discussed. What Are ZFS Snapshots and Clones? A snapshot is simply an exact picture of the state of your data at a certain point in time. For example, let’s say you’re working on a complex website. You
