About the file hash search in NetBackup
You can search the files using the file hash of the file. The file hash search is supported on the accelerator backups. After you enable this feature, the SHA-256 hash of the files is calculated during the client backups and saved to the NetBackup primary server catalog.
The file hash calculation is supported only for normal files. The sparse file, symbolic link, and any other special files are not supported.
Perform the following steps to configure and use the feature:
Configure file hash server.
Enable Calculating the file hash.
Search for files using the file hash.
The NetBackup primary server, media server, and a client must be 10.5 or later to use this feature.
