neo4j对于数据库的读取导入和导出Dump and load databases

Dump and load databases

neo4j-admin dump --database= --to=

neo4j-admin load --from= --database= [--force]

 

Dump the database called graph.db into a file called /backups/graph.db/2016-10-02.dump. The destination directory for the dump file — in this case /backups/graph.db — must exist before calling the command.

$neo4j-home> bin/neo4j-admin dump --database=graph.db --to=/backups/graph.db/2016-10-02.dump

$neo4j-home> ls /backups/graph.db

$neo4j-home> 2016-10-02.dump

Load the backed-up database contained in the file /backups/graph.db/2016-10-02.dump into database graph.db. Since we have a database running, we first have to shut it down. When we use the --force option, any existing database gets overwritten.

$neo4j-home> bin/neo4j stop

Stopping Neo4j.. stopped

$neo4j-home> bin/neo4j-admin load --from=/backups/graph.db/2016-10-02.dump --database=graph.db --force
