WeCan provides raw WAX snapshots
Nodeos was configured with: chain-state-db-size-mb = 131000
Nodeos versions compatible with the snapshots: 3.1.0-3.2.0, 3.x.x, 4.x.x
Snapshots are available at https://backup.wecan.dev/wax/ , and below are individial links for every chain.
Keep in mind that the format of snapshots is raw uncompressed, so it may take some time to download them.
The snapshot dates are represented in epoch dates e.g. "1650022193" equals to "Friday, April 15, 2022 11:29:53 AM".
Use https://www.epochconverter.com/ for dates conversion.
Nodeos snapshot restore is described here: How to restore snapshot with full history
Atomic Assets backups for WAX.
Postgres database backup was taken from Postgres 13.
The backup was taken with command "pg_dump -Fc -Z 0"
thus in order to restore the dump this flag must be used as well "pg_restore --verbose -Fc"
The database dates are also represented in epoch dates e.g. "atomic.mainnet.1650022193.dump".
Hyperion Elasticsearch snapshots can be downloaded here too.
Elasticsearch snapshots were cut from Elastic version 7.16.3 which should be compatible with the newer Elastic versions
The compatibility chart can be found here: Elasticsearch snapshot-restore
Light-API (https://github.com/cc32d9/eosio_light_api) backups for WAX.
MariaDB database backup was taken from MariaDB 11.2.2.
The Chronicle snapshot was taken from Chronicle 3.3
Refer to Chronicle docs for more info https://github.com/EOSChronicleProject/chronicle-tutorial
The database and chronicle shapshot dates are also represented in epoch dates e.g. "wax.snapshot_1704274922" and "lightapi_db.sql.1704183241.dump".
Wget HTTP recursively into directory:
mkdir -p /srv/wax/data
cd /srv/wax/data
wget -r -nH -np -A "*.log,*.index,snapshot*.bin" -R "*html*,*.txt,shared_memory.bin" https://backup.wecan.dev/wax/mainnet/1650022193/
To resume wget download in case of connection interruption:
wget -c -r -nH -np -A "*.log,*.index,snapshot*.bin" -R "*html*,*.txt,shared_memory.bin" https://backup.wecan.dev/wax/mainnet/1650022193/
Parallel downloading with aria2c (no recursive list supported yet):
mkdir -p /srv/data
aria2c -c -s 10 -x 10 --file-allocation=none https://backup.wecan.dev/wax/mainnet/1650022193/state-history/trace_history.log
Restore AA postgres dump example:
1. PGPASSWORD=***** dropdb -U aa_user "api-wax-mainnet-atomic-1"'
2. PGPASSWORD=***** createdb -U aa_user "api-wax-mainnet-atomic-1"
3. PGPASSWORD=***** pg_restore --verbose -Fc -j 16 -U aa_user --no-owner --role=aa_user -C -d api-wax-mainnet-atomic-1 /snapshots/atomic.mainnet.1650022193.dump
Restore Light-API Chronicle snapshot and DB dump:
1. mariadb -u root -plightapi lightapi < /var/lib/snapshots/lightapi_db.sql.dump
2. /usr/local/sbin/chronicle-receiver --config-dir=/var/local/chronicle/chronicle-config --data-dir=/var/local/chronicle/chronicle-data --restore-snapshot=/var/local/chronicle/wax.snapshot
Adding WeCan Elasticsearch snapshot repository and restoring a snapshot (testnet or mainnet accordingly) (can be done over Kibana entierly):
1. Add this to each Elastic node config:
vim /etc/elasticsearch/elasticsearch.yml
repositories.url.allowed_urls: "https://backup.wecan.dev/wax/hyperion/mainnet/"
and restart the nodes gracefully.
2. Register the snapshot repository:
curl -XPOST -u user:password \
-H "Content-Type: application/json" \
--url "http://localhost:9200/_snapshot/wecan_hyperion_mainnet" \
-d '{ "type": "url", "settings": { "url": "https://backup.wecan.dev/wax/hyperion/mainnet/" } }'
3. Verify snapshots in the repository:
curl -XGET -u user:password \
-H "Content-Type: application/json" \
--url "http://localhost:9200/_snapshot/wecan_hyperion_mainnet/_all"
4. Restore latest successful snapshot:
curl -XPOST -u user:password \
-H "Content-Type: application/json" \
--url "http://localhost:9200/_snapshot/wecan_hyperion_mainnet/weekly-hyperion-mainnet-2022.06.26-c6cnnuywsmqrqj9gdpsokg/_restore" \
-d '{ "indices": "*,-.*" }'
