How can I back up AllegroGraph data?
There are 3 ways: 1. If you want to dump the triples to an ascii file in ntriples format you just can do: (defun dump (name) (with-open-file (out name :direction :output :if-exists :supersede) (print-triples (get-triples) :format :ntriple :stream out :limit nil))) The advantage of this approach is that you output valid RDF ntriples. The disadvantage is that you lose the named graphs and encoded triples. 2. Another human-readable format which does preserve named graphs is TriX: (with-open-file (out name :direction :output :if-exists :supersede) (db.agraph.serializer:serialize-trix *db* out)) 3. A binary dump can be done by copying the entire database directory minus all the files that start with index. You could save the index files too but those can always be regenerated again.
