Hi,
solrBackup is the default directory position for automated backup copy of solr indexes.
In Alfresco 4.1 you can find 2 properties in WEB-INF/classes/alfresco/subsystems/Search/solr/solr-backup.properties


solr.backup.alfresco.remoteBackupLocation=${dir.root}/solrBackup/alfresco
solr.backup.archive.remoteBackupLocation=${dir.root}/solrBackup/archive
‍‍‍‍

In the Enterpise version you can set these properties accessing Share

In the Community version you can set alfresco-global.properties


# the backup path
solr.backup.alfresco.remoteBackupLocation=${dir.root}/solrBackup/alfresco
solr.backup.archive.remoteBackupLocation=${dir.root}/solrBackup/archive
# the number of backups to keep
solr.backup.alfresco.numberToKeep=3
solr.backup.archive.numberToKeep=3
# the backup scheduler
solr.backup.alfresco.cronExpression=0 0 2 * * ?
solr.backup.archive.cronExpression=0 0 4 * * ?

Putting this here in case someone was trying to find what I was after.

If you want to restore solr4 indexes from solr4Backup folder follow these steps
(works for Alfresco Community 5.2 on centos 7 64 bit)

1. stop solr / tomcat

sudo service alfresco stop tomcat

2. delete current indexes usually stored in {alf_data}/solr4/index. check 'data.dir.root' setting in alfresco-global.properties

cd /opt/alfresco-community/alf_data/solr4
sudo rm -rf index/workspace/SpacesStore/index/*
sudo rm -rf index/archive/SpacesStore/index/*

3. restore backups from solr4Backup folder. usually stored {alf_data}/solr4Backup

cd /opt/alfresco-community/alf_data/solr4Backup
sudo cp -R alfresco/{some snap shot}/* ../solr4/index/workspace/SpacesStore/index/
sudo cp -R archive/{some snap shot}/* ../solr4/index/archive/SpacesStore/index/

4. start solr / tomcat

sudo service alfresco start tomcat
