Snapshots allows a new node to join the network by recovering application state from a backup file. Snapshot contains compressed copy of chain data directory. To keep backup files as small as plausible, snapshot server is periodically beeing state-synced.
Snapshots are taken automatically every 6 hours starting at 00:15 UTC
