Hi all, DAS uses Apache Lucene as the indexing engine underneath.Usually Lucene keeps its indexed data in the local filesystem . But in the DAS implementation, the internal Lucene keeps its data in the DAS Data Access Layer (DAL), in a store called the "FileSystem".
The previous implementation of the Backup Tool added the support to backup analytics tables from the record store to the local file system as well as restoring them. But after restoring the records, there's no way of re-indexing the data unless the records are published again thus, the index search cannot be used after a restore ( if the indexed data is not there). Therefore we added the functionality of backing up the index data of Lucene to the local filesystem as well as restoring the backed up indexes. Now the backup tool supports backing up all the records along with its indexes to the local system and allows a backed up DAS system to be restored into a new one using the backup tool.
