what about the database?

CSC B2share-environment:

B2Share PostgreSQL databases (pgsgl/Invenio) are backed up every night via cron scripts to /data/backup-directory.
When restoring the backup of the whole system, you'd need the latest one of the database backups from where you'll restore the invenio and pgsql databases after you have restored all the other files to operating system, b2share in /opt and datafiles in /data.
For restoration you'd need the root access to the system and necessary database administration passwords.

Restoring database from backup dumps.
Databases (psql and invenio) are snapshotted/dumped every night. After you have restored the file-structure to the /data-volume, you need to restore the databases.
To import a backed up database, unpack the gzipped database dump you need (in this case they are located in /data/backup/-directory), then sudo yourself to postgres and run: psql invenio < /where/your/unzipped/database/file/resides.
Restart b2share (cd /your/b2share/installation/folder/b2share/; docker-compose down;docker-compose up -d).
