I think someone will write a wiki/manual for the new backup tool soon, and there'll be multiple ways of accessing it also, f.ex. through java code, through a script and maybe through JMX a.s.o. but for the time being the java code works like this:
o To have your running graph database support clients connecting to it and fetching online backups just have the neo4j-com and neo4j-backup jars (with its dependencies, like netty) on the classpath, that's it. o The code to perform an online backup<https://github.com/neo4j/graphdb/blob/master/backup/src/main/java/org/neo4j/backup/OnlineBackup.java>looks like this: OnlineBackup.from( "localhost" ).full( "directory/to/backup/to" ).close(); .... then, at a later time .... OnlineBackup.from( "localhost" ).incremental( "directory/to/backup/to" ).close(); Or you can store the OnlineBackup object and close whenever you feel like. 2011/2/9 Peter Neubauer <[email protected]> > Gian and all, > we are moving the OnlineBackup component onto the Hich Availability > logic.
