ZFS Snapshots

ZFS snapshots are like saved states of your data at a specific moment in time. They record the exact structure and contents of your files and folders without copying everything—just the differences. This allows you to easily revert to a previous version if needed, such as recovering lost files or undoing unwanted changes. Snapshots are efficient, using minimal additional space, and can be created quickly. They are useful for backup, data integrity, and recovery, providing a reliable way to track and restore your data without disrupting ongoing work.
