Neo4j - Backup & Restore


Advertisements


In real-time applications, we should take backup of our application database regularly, so that we can restore to some working condition at any failure point.

This rule is applicable for both RDBMS and NoSQL databases.

In this section, we are going to discuss about two important DBA tasks.

  • How to back up a Neo4j Database.
  • How to restore Neo4j Database to a specific backup.

Note − These steps are applicable to Windows Operating System only. We should use similar kind of commands to do the same steps in other operating systems.

Neo4j Database Backup

Step 1 − Click "Neo4j Community" using the following path −

Windows "Start" button → "All Programs" → "Neo4j Community" → "Neo4j Community"

By default, it selects c:\Users\[username]\Documents\Neo4j\default.graphdb. However if we wish to, we can change the path to a different directory.

Step 2 − Here we have changed to our Neo4j Database folder.

C:\Ne04j2.0db
