This is a very critical issue for us.
We have an external centos machine which takes the an online backup for our 3.5 neo4j production.
It has recently started failing without any changes or upgrade.
It fails after this step. (Start recovering store)

Failure message is :

Can you help us understand what " (Start recovering store) " step does? Also How can we go about fixing this?
We essentially run
$NEO4J_ADMIN_PATH backup --from=$NEO4J_DB --backup-dir=$BACKUP_DIR --name=$BACKUP_NAME --fallback-to-full=true --check-consistency=false --pagecache=4G >> $LOG_PATH to start our backup.
