comment Neo4j service won't start with an imported database on Debian
Oh right, permissions. Actually Neo4j should output warnings, it probably tries to write to messages.log which it can't write to either.

did you use the same neo4j-version to create the data and start the server?

comment Use Database to Store Data Extracted From Internet
Yes something like Neo4j makes a lot of sense for this kind of data. Esp. if you want to analyse graph structures later on.

comment Is NoSQL a replacement for traditional SQL, or an addition?
Actually it means "Not Only SQL" and embraces polyglot persistence. See the article by Martin Fowler (martinfowler.com/bliki/PolyglotPersistence.html). And there is a range from NOSQL stores handling large amounts of simple data to NOSQL stores handling complex, rich data (skillsmatter.com/podcast/nosql/…)

comment Can NoSQL databases cause occasional data loss?
Neo4j is a NOSQL (graph) database that is actually ACID compliant. It comes with full transaction support and durable persistence. Neo4j also uses transaction-logs to secure write operations before applying them to the datastore. Disclaimer: I work for Neo Technology.

comment Amount of data per node in Neo4j
How big are your chunks in general? You should make sure to find a suitable string_block_size to keep the number of string blocks in the storage down to a reasonable level as well as not wasting too much space in only half-filled blocks. How will the data be used? Just rendered or also queried/processed otherwise? If you need to save space, compression + storage as byte array can be an option.
