Description: A filesystem snapshot is a read-only copy of the filesystem at a specific moment. This technique allows capturing the state of a filesystem at a given instant, facilitating data recovery and version management. Snapshots are especially useful in environments where data integrity is critical, as they enable restoring the system to a previous state without needing to perform full data backups. Snapshots can be implemented at the software or hardware level, and their use has become common in various operating systems and virtualization platforms. In general, snapshots allow users to revert unwanted changes or recover accidentally deleted files. In virtualization environments, snapshots enable efficient management of virtual machines, facilitating testing and development without the risk of data loss. Additionally, in the context of cloud recovery, snapshots are an essential tool for ensuring data availability and integrity, allowing organizations to quickly restore their systems in the event of failures or cyberattacks.
