数据备份恢复
现有三台ONgDB服务器，2-CORE，1-REPLICA。备份操作采用远程备份的方式，不在生产服务器备份。
备份命令
ongdb@ip-10-20-0-157:~/ongdb-enterprise-3.5.17$ ./bin/neo4j-admin backup
Missing argument 'backup-dir'
usage: neo4j-admin backup --backup-dir=<backup-path> --name=<graph.db-backup>
[--from=<address>] [--protocol=<any|catchup|common>]
[--fallback-to-full[=<true|false>]]
[--timeout=<timeout>] [--pagecache=<8m>]
[--check-consistency[=<true|false>]]
[--cc-report-dir=<directory>]
[--additional-config=<config-file-path>]
[--cc-graph[=<true|false>]]
[--cc-indexes[=<true|false>]]
[--cc-label-scan-store[=<true|false>]]
[--cc-property-owners[=<true|false>]]
environment variables:
NEO4J_CONF Path to directory which contains neo4j.conf.
NEO4J_DEBUG Set to anything to enable debug output.
NEO4J_HOME Neo4j home directory.
HEAP_SIZE Set JVM maximum heap size during command execution.
Takes a number and a unit, for example 512m.
Perform an online backup from a running Neo4j enterprise server. Neo4j's backup
service must have been configured on the server beforehand.
All consistency checks except 'cc-graph' can be quite expensive so it may be
useful to turn them off for very large databases. Increasing the heap size can
also be a good idea. See 'neo4j-admin help' for details.
For more information see:
https://neo4j.com/docs/operations-manual/current/backup/
options:
--backup-dir=<backup-path> Directory to place backup in.
--name=<graph.db-backup> Name of backup. If a backup with this
name already exists an incremental
backup will be attempted.
--from=<address> Host and port of Neo4j.
[default:localhost:6362]
--protocol=<any|catchup|common> Preferred backup protocol
[default:any]
--fallback-to-full=<true|false> If an incremental backup fails backup
will move the old backup to
<name>.err.<N> and fallback to a full
backup instead. [default:true]
--timeout=<timeout> Timeout in the form <time>[ms|s|m|h],
where the default unit is seconds.
[default:20m]
--pagecache=<8m> The size of the page cache to use for
the backup process. [default:8m]
--check-consistency=<true|false> If a consistency check should be
made. [default:true]
--cc-report-dir=<directory> Directory where consistency report
will be written. [default:.]
--additional-config=<config-file-path> Configuration file to supply
additional configuration in. This
argument is DEPRECATED. [default:]
--cc-graph=<true|false> Perform consistency checks between
nodes, relationships, properties,
types and tokens. [default:true]
--cc-indexes=<true|false> Perform consistency checks on
indexes. [default:true]
--cc-label-scan-store=<true|false> Perform consistency checks on the
label scan store. [default:true]
--cc-property-owners=<true|false> Perform additional consistency checks
on property ownership. This check is
*very* expensive in time and memory.
[default:false]
修改集群配置
# Enable online backups to be taken from this database.
dbms.backup.enabled=true
# By default the backup service will only listen on localhost.
# To enable remote backups you will have to bind to an external
# network interface (e.g. 0.0.0.0 for all interfaces).
# The protocol running varies depending on deployment. In a Causal Clustering environment this is the
# same protocol that runs on causal_clustering.transaction_listen_address.
dbms.backup.address=0.0.0.0:6362
causal_clustering.transaction_listen_address=:6000
