Note

To get higher scalability for content indexing files from backups, you can turn off the generate previews option on the Search Engine node. When generate previews is off, each search node can accommodate approximately twice the number of objects per node. For example, in a large enterprise, this would be approximately 40 TB of source data (about 60 million objects), and the required disk space is 15% of source data (up to 6 TB).
