Snapshot

EchoVault can take periodic snapshots of the current data and store it on disk. There are 2 configuration values used to configure the snapshot behaviour:

  • --snapshot-threshold - The number of write commands before a snapshot is triggered. The default number is 1,000 write commands.
  • --snapshot-interval - The interval between snapshots. It accepts a parseable time format such as 30m45s or 1h45m. The default is 5 minutes.

To restore data from a snapshot, set the --restore-snapshot configuration flag to true when starting a new EchoVault instance. Make sure to set the --data-dir to the folder containing the snapshot file so EchoVault knows where to load the file from.

You can trigger a snapshot manually using the SAVE command.

When both of these configuration options are set, the snapshot is triggered by whichever one is reached first since the instance's initialization or the last snapshot.
