  Best Practices for Adding Large Filesystem Clients -Ensure the file cache is sized properly -Work with support / account teams to investigate using cache prefixing for clients with many millions of files -For initial backups: On low capacity grids, use overtime to allow the backup to complete On higher capacity grids, allow the client to time out daily and rely on partial backups For clients that will not complete within 7 days, start with a small dataset and gradually add more files and directories to avoid issues with parials backups expiring before the initial backup completes -For incremental backups: Typical backup performance is about 1 million files per hour Generally the client disk performance is the bottleneck but be sure to confirm the bottleneck before making any performance tweaks
