Restoring Jena Backup over HTTP using file location as parameter
Hi,
I am trying to explore Jena Backup and restore options using fuseki
administrative http protocol
I am running below http command for taking the backup
*curl -i -X POST http://localhost:3030/$/backup/backuptest
<http://localhost:3030/$/backup/backuptest>*
And below command for restoring the backup
*curl -i -X PUT -H "Content-Type: application/n-quads" -d
@"run\backups\backuptest_2021-02-08_10-09-12.nq\backuptest_2021-02-08_10-09-12.nq"
http://localhost:3030/backuptest/ <http://localhost:3030/backuptest/>*
While it is working but I need to pass the file with Http put request for
backup is there any way to just pass the file location for restoring?
Note: I have already explored restoring backup using TDBloader2 but need to
stop the fuseki so not meeting our requirements.
Regards,
Deepali

You don't need to use SPARQL.
Simply use "curl" or "wget" as a HTTP GET on the dataset URL (if you
have service GSP enabled).
Use the 'Accept" header for the syntax you want.
(There's an operation in the RDFConnection API to do this as well).

Hi Andy,
How we can write SPARQL query to fetch backup of entire dataset including
all graphs and use the result to restore it?

Deepali

That intentionally puts the backup on the server local disk so it is not
accessible from the outside. It is an admin operation with the
expectation that it is an admin task to reload the database if needed
(using tdbloader offline then swapping it into a server which is a
restart currently).
If you want to do remote backup, simply send a SPARQL query to fetch the
database.
