Best Practices

To obtain the best results with local index storage, apply the following best practices:

• Use a volume dedicated to the index cache directory formatted with a block allocation size of 32K.

  Note

  In Red Hat Linux, the block allocation size cannot be more than 4K. Therefore, when using Red Hat Linux, use a volume dedicated to the index cache directory formatted with a block allocation size of 4K.

• Configure antivirus exclusions for Windows and UNIX.

• For Microsoft Windows MediaAgents, disable Microsoft Windows indexing service on the drive where the index cache resides.

• For Microsoft Windows MediaAgents, do not enable Windows Deduplication on a volume that contains the index cache directory, as this may cause a significant drop in performance and may cause jobs to fail.

• Do not locate the index cache directory on the system drive of the MediaAgent hosting it.

• Do not locate the index cache directory on a compressed drive.

• For best performance, locate the index cache directory on a solid state drive (SSD) disk.

• Do not locate the index cache directory folder directly under the <software_installation_directory>.

• For UNIX, do not specify root as the index cache directory.

• When entering the index cache directory path or the index log cache directory path, note the following:

  • The path may not exceed a total of 75 characters.

  • The path may not contain special characters.

  • The path may not contain Unicode characters.

  • The path may not contain the word "temp" (for example, c:\Indexcache_temp)
