Restore from snapshot

To speed up the initial blockchain synchronization the node database can be restored from a snapshot following the below steps:

  • delete the contents of the database if the node has been started already

  • download the database snapshot

  • verify if the snapshot checksum matches the downloaded file

  • unarchive the database snapshot

Note that the docker container must be stopped before replacing the database

The following snippet can be used to replace the current database with the latest mainnet snapshot assuming the database path is ~/.aeternity/maindb:

rm -rf ~/.aeternity/maindb/ && mkdir -p ~/.aeternity/maindb/
curl -o ~/.aeternity/mnesia_main_v-1_latest.tar.zst https://aeternity-database-backups.s3.eu-central-1.amazonaws.com/main_backup_v1_full_latest.tar.zst
CHECKSUM=$(curl https://aeternity-database-backups.s3.eu-central-1.amazonaws.com/main_backup_v1_full_latest.tar.zst.md5)
diff -qs <(echo $CHECKSUM) <(openssl md5 -r ~/.aeternity/mnesia_main_v-1_latest.tar.zst | awk '{ print $1; }')
test $? -eq 0 && tar --use-compress-program=unzstd -xf ~/.aeternity/mnesia_main_v-1_latest.tar.zst -C ~/.aeternity/maindb/
