Backup/restore with Neo4j Enterprise

First of all, backups for Neo4j Enterprise need to be enabled in the neo4j.conf file:

dbms.backup.enabled=true
dbms.backup.address=192.168.0.100:6362

Performing a full backup involves running the backup command with the Neo4j admin tool:

    bin/neo4j-admin backup --from=192.168.0.100 --backup-dir=/backups/ --name=astronaut.db-backup
    Doing full backup...

This should create a new astronaut.db-backup file in the /backups/ directory.

The same command will invoke an incremental backup if the following conditions are met:

  • The backup location exists
  • All transaction logs from the time of the prior backup to the present exist
    bin/neo4j-admin backup --from=192.168.0.100 --backup-dir=/backups/ --name=astronaut.db-backup --fallback-to-full=true
    Destination is not empty, doing incremental backup...

Using the fallback-to-full=true option ensures that a full backup will be taken, should the incremental backup fail.

It is a good idea to ensure that backup files are moved off the database instance to ensure survivability in the event of a disk or other hardware failure.

Restoring from a backup is done in a similar manner. Before restoring from a prior backup, the Neo4j instance must first be shut down:

    neo4j stop
If you are running in a causal or HA cluster configuration, be sure to shut down all clustered Neo4j instances.

Once the instance has been shut down, the database can be restored with the following command:

    bin/neo4j-admin restore -from=/backups/astronaut.db-backup --database=graph.db --force

The -force option is necessary here to ensure that the current database is overwritten in favor of the one contained in the backup. Once the restore command is completed, restart Neo4j on the instance to bring the restored database online.
