--------------------------------------------
Summary: Implement a Backup/Restore infrastructure
Key: MARMOTTA-276
URL: https://issues.apache.org/jira/browse/MARMOTTA-276
Project: Marmotta
Issue Type: Task
Components: Platform
Reporter: Sebastian Schaffert
Assignee: Sebastian Schaffert
Fix For: 3.2-incubating
Currently it is very difficult backing up all system data and restoring it in a
new instance. This would be very useful for version upgrades, for moving from
staging to production servers, etc.
Backup/Restore could be implemented by a generic backup service that provides
basic infrastructure for storing the backup data and restoring it, and an
interface that every component can implement to store its own data. Instances
of this interface can then be injected via CDI.
The components would at least provide the following backup functionalities:
marmotta-core:
- backup each context/named graph into an RDF file (e.g. Turtle), except the
volatile contexts (reasoning, caching)
- backup the system configuration (Configuration Service) into a properties file
marmotta-reasoner
- backup all reasoning programs; when restored, the programs need to be
re-evaluated on the triple store
Other components need to be checked. Versioning information does not need to be
backed up (it would also be difficult).
