Moonbeam Relay Chain (Polkadot pruning 256) Backup
Note - These backups have only been tested on recovering the RocksDB Polkadot relay pruned (256) database and Moonbeam parachain databases (multiple options below) on a Moonbeam Collator node.
It is not intended to be used on any other node or in any other way than described below.
IMPORTANT: These should only be used for testing purposes. For production, the best practice is to sync your node over the network from beginning.
Only recover from backups off of a private backup copy which you have created (CertHum does not use these backups and recovers from private copies.)
These backups are NOT endorsed by the Moonbeam Foundation or any other 3rd party.
DEPENDING ON WHICH CHAIN YOU ARE RECOVRING, YOU WILL NEED TO PURGE YOUR CHAIN. FOLLOW THE MANUAL INSTRUCTIONS FROM MOONBEAM FOUNDATION. https://docs.moonbeam.network/node-operators/networks/run-a-node/systemd/#purge-your-node ALWAYS MAKE SURE YOU ARE USING THE CLIENT VERSION THAT MATCHES THE SNAPSHOT VERSION. WE TRY TO RETAIN WITH N-1, BUT IF IN DOUBT, USE THE MOST RECENT.
These should be only restored in the following directory (do not alter directory path because it may corrupt your node after service restarts):
/var/lib/moonbeam-data/polkadot/chains/polkadot/db - for the Polkadot Pruned RocksDB database
/var/lib/moonbeam-data/chains/moonbeam/db- for the Moonbeam DB.
Tested on Ubuntu 20.04
Pre-req - zstd.
Recovering this backup to any directory path other than the one provided above will impact crash consistency and potentially corrupt your database on process failure. This may result in financial loss.
