备份neo4j社区版在unix：mac或linux脱机 [英] Backup neo4j community edition offline in unix: mac or linux

问题描述

以前，我在进行备份时遇到了问题，如 question 在尝试还原数据库时出现错误，因为我在数据库运行时执行了副本。

Previously I had a problem when making a 'backup' as shown in this question where I get an error when trying to restore the database because I did a copy when the database was running.

我试过这个：

• 我创建了一些节点和关系，很少像10（矩阵示例）。


• 然后我停止了服务neo4j


• 我将包含graph.db的文件夹数据复制到另一个位置


• 之后，我删除了graph.db文件夹并启动neo4j


• 它自动创建一个新的graph.db文件夹，数据库运行为新的没有任何数据，这是正常的。


• 然后我再次停止并粘贴旧 graph.db 文件夹

• I created some nodes and relations, very few like 10 (the matrix example).
• Then I stopped the service neo4j
• I copied the folder data that contains graph.db to another location
• After that I deleted the graph.db folder and started neo4j
• It created automatically a new graph.db folder and the database runs as new without any data, that is normal.
• Then I stopped again and paste the old graph.db folder

我收到错误：

 Starting Neo4j Server...WARNING: not changing user waiting 
 for server to be ready... Failed to start within 120 seconds.

错误在5秒后出现，而不是120秒后。

The error appears after 5 seconds not after 120 seconds.

• 我尝试粘贴名为数据的文件夹。同样的错误。
  

• I tried pasting the folder called data. Same error.

我应如何在neo4j社区中手动备份和恢复？

我读了一些你只能复制和恢复但不起作用的帖子。

I read in some posts that you only copy and restore but that does not work.

感谢您的帮助

推荐答案

在Neo4j正在运行时，在线备份，在采取一致的备份的意义上，仅在Neo4j企业版中可用。

Online backup, in a sense of taking a consistent backup while Neo4j is running, is only available in Neo4j enterprise edition. Enterprise edition's backup also features a verbose consistency check of the backup, something you do not get in community either.

社区版中唯一安全的选择是彻底关闭Neo4j和递归复制掉graph.db文件夹。我通常使用：

The only safe option in community edition is to shutdown Neo4j cleanly and copy away the graph.db folder recursively. I'm typically using:

cd data
tar -zcf graph.db.tar.gz graph.db/

要恢复您关闭neo4j，请清除现有的graph.db文件夹并恢复原始图形。 db文件夹：

For restoring you shut down neo4j, clean out a existing graph.db folder and restore the original graph.db folder from your backup:

cd data
rm -rf graph.db
tar -zxf graph.db.tar.gz
