Hi, My question is about Apache Jena Fuseki.
Here is my situation. I backed up about 50G (Fuseki\run\databases\MYDATANAME) data using the backup button, and I got the backup from 'Fuseki\run\backups', the file is MYDATANAME.nq.gz. It is about 2G. [image: Inline image 1] When I was trying to upload the backup into a new server. Upload will be interrupted and Fuseki stopped with the error 'java heap space'. So I enlarged the space in file Fuseki\fuseki-server.bat. 50G failed with the same error. I kept meeting 'java heap space' until I changed it into 60G (My RAM is 64G). Then it uploaded successfully. [image: Inline image 2] My database will keep on increasing. I was worried in the future when I backup my data with larger size, I will be unable to upload them with the limited RAM. *When making the backup, is there any way to make the backup into several small pieces, or anyway to backup with specific limitation* (For example: The whole data contains everyone's data int a country, the backup of everyone's data in the country is very large and there may don't have enough RAM for it to upload. So when making the backup, I can use some search sentences to restrict it into one province's people data, after backup each province, I will got the whole data of my old server.), or i can use command line to restrict my backup? I didn't find information about it from the documentation of Fuseki. Thank you very much! Sincerely, Sherry
