Re: [Neo4j] Online backups for single instance using community edition
Yes,
that would be a good solution for a small graph. Go for it and let us
know how it works out! However, GraphML does not save your indexes and
other triggers, just the raw graph. So, if you do this, be sure not to
have data that is only in you indexes and not in the graph, and write
an importer that can index the relevant parts again, if you are using
indexes.
For making this easier, you might consider contributing to Nigel
Smalls GEOFF plugin, see
https://github.com/nigelsmall/neo4j-geoff-plugin that can capture even
the index info and thus is better (albeit younger) than GraphML. You
said you wanted to code!

Re: [Neo4j] Online backups for single instance using community edition
I thought about that, yes, but I think it can easily become tricky in my
case. If it is the only way than I have to do some magic at the application
layer to tell users that they currently can't post comments but the read
access would be vital.
What about exporting a graph with g.saveGraphGML('backuped.xml')? I could do
this by using curl to post to the gremlin plugin but I am not quite sure how
this is implemented yet. I assume it creates a snapshot of the current graph
without including non finished transactions (which would be fine). If
anything happens to the db I'll read in the exported file again. Is this a
considerable way of solving the issue (for moderately sized graphs) or am I
missing something obvious?
Greetings,
Hannes

Re: [Neo4j] Online backups for single instance using community edition
Johannes, if you can make sure that no transaction are in progress, then copying files should work, too. Would that help? You could for instance for a brief period block mutating requests to your webservice, commit all transactions and copy the store files.

[Neo4j] Online backups for single instance using community edition
Hi, I am using the neo4j community edition in a PHP webapp that I am currently developing and found it to be a really cool solution for my project. It is a small project and I am just a single guy developing it so I am nowhere near needing HA or sharding capabilities. Here is the problem I see with neo4j in any form of webapp (SaaS): To be able to create an online backup you'll have to use the enterprise edition (=2000 dollars a month) or you are forced to shutdown the service for a short period of time (most likely multiple times per day) which can be an absolute no-go for a webapp. So my question is: Is there another method of doing an online backup for a single neo4j instance? I thought about traversing the whole graph and creating a second graph filled with the result. I could then shutdown the second instance and just backup the files old school style. This sounds super ugly, but maybe it is a way to think about. I am fine with solutions that would require some additional developing. If the only solution is to use the enterprise edition than I would highly suggest some alternative ways for the next neo4j releases as this would prevent a lot of webdevelopers from using the product. It would be nice to have a way to do online backups for a single instance only so the benefits of the advanced and enterprise editions would still exist. Anyways, thanks for your time and answers Greetings from Austria, Hannes -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Online-backups-for-single-instance-using-community-edition-tp3415246p3415246.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
