An incremental backup is performed whenever an existing backup directory is specified. The backup tool will then copy any new transactions from the Neo4j server and apply them to the backup. The result will be an updated backup that is consistent with the current server state.
However, the incremental backup may fail for a number of reasons:
- If the existing directory doesn’t contain a valid backup.
- If the existing directory contains a backup of a different database store.
- If the existing directory contains a backup from a previous database version.
Note that when copying the outstanding transactions, the backup tool needs
access to the historical logical logs. These logical logs are kept by Neo4j and
automatically removed after a period of time, based on the
