Description
Hi. I want do a backup of my magnolia author instance, can it do via API:
curl --location 'https://<server>/.rest/commands/v2/backup/backup' \ --header 'Content-Type: application/json' \ --header 'Authorization: Basic <credentials>' \ --data '{ "repositoryPath": "/mgnl_author/mgnl_data/repositories/author", "configurationPath": "/mgnl_author/mgnl_conf/jackrabbit-bundle-mysql-search.xml", "backupLocation": "/mgnl_author/backups/01", "compression": false }'
When I execute the curl, in the catalina.out show this:
---------------------------------------------------------------- Mon Oct 02 11:49:29 CEST 2023: Booting Derby version The Apache Software Foundation - Apache Derby - 10.14.2.0 - (1828579): instance 5b0eecb3-018a-ef6e-3aaf-0000281784c0 on database directory /mgnl_author/backups/01/version/db with class loader ParallelWebappClassLoader context: author delegate: false ----------> Parent Classloader: java.net.URLClassLoader@37f8bb67 Loaded from file:/opt/tomcat/apache-tomcat-9.0.41/webapps/author/WEB-INF/lib/derby-10.14.2.0.jar java.vendor=Red Hat, Inc. java.runtime.version=1.8.0_352-b08 user.dir=/ os.name=Linux os.arch=amd64 os.version=3.10.0-1160.80.1.el7.x86_64 derby.system.home=null Database Class Loader started - derby.database.classpath='' ----------------------------------------------------------------
three times, and show this line:
INFO ule.backup.executor.ObservationAwareBackupExecutor: An error occurred while backup was ongoing, therefore, retrying to backup once more.
Finally show a error track with this message:
javax.jcr.RepositoryException: Failed to copy content ... Caused by: org.apache.jackrabbit.core.data.DataStoreException: Record ccc2fab22bfe8fc035c4fd7dd105d27b3bb74d1fb327c97d3bbf4a02c41725df does not exist
I readed this incidence now closed https://jira.magnolia-cms.com/browse/MGNLBACKUP-143
In this incidence comment that the solution is repair the datastore, so in the logs not found a record because not exist.
In the incidence comment that doing this:

Can work, but not work.
I don't understand very well the error.
But understand that the datastore folder in the author instance contains the database data indexs and as in the folder exist the path repositories/author/magnolia/repository/datastore/cc/c2/fa/ with the file ccc2fab22bfe8fc035c4fd7dd105d27b3bb74d1fb327c97d3bbf4a02c41725df. Magnolia is searching this uuid in the database and this not exist. Is correct?
The solution is reparir the datastore, How to I do this? Understand that the repositories must have the same indexs that in the database...Is correct?
Someone know as solved it?
Thank you very much.
