In the example above, the EncryptType field shows that file /etc/test/file1 is encrypted using "128bit AES" or that the "encryptiontype aes128" client option was used to encrypt the file.
With the Tivoli Storage Manager Backup-Archive client at version 6.2 or above, run the following command :
dsmc query backup <filespec> -detail
For example, to display encryption information for file c:\test\file1.txt :
C:\Program Files\Tivoli\TSM\baclient>dsmc query backup c:\test\file1.txt -detail
