Netdata Snapshot and Restore Workflow
Creating Snapshots
Netdata provides a snapshot feature that allows you to capture the current state of your system and save it for later reference. This can be useful for troubleshooting and debugging purposes.
To create a snapshot, you can use the `netdata snapshot` command. This will create a compressed archive of the current system state, which can be saved to a file or uploaded to a remote server.
Restoring Snapshots
If you need to restore your system to a previous state, you can use the `netdata restore` command. This will apply the snapshot to your system, restoring it to the state it was in when the snapshot was taken.
