Osquery Snapshot and Restore Workflow
Creating Snapshots
Osquery allows administrators to create snapshots of endpoint data, which can be used for auditing and compliance purposes.
To create a snapshot, use the following command:
osqueryi --snapshot /path/to/snapshot
Restoring Snapshots
Osquery also allows administrators to restore snapshots, which can be useful in case of data loss or corruption.
To restore a snapshot, use the following command:
osqueryi --restore /path/to/snapshot
Osquery vs Alternatives
Comparison with Other Tools
