When the save option is specified for an API application (does not apply toMac OS X), the initial key password must be provided by the application usingthe API in the dsmInitEx function call. The API itself does not issue a promptto the user but relies on the application to prompt the user as necessary.This is the default.Restrictions:v This option can only be used when passwordaccess generate is also specified.v The root user or a Tivoli Storage Manager authorized user must specify theinitial encryption key password.promptThe management of the encryption key password is provided by the user. Theuser is prompted for the encryption key password when the Tivoli StorageManager client begins a backup or archive. A prompt for the same password isissued when restoring or retrieving the encrypted file. This password can beup to 63 bytes in length.When the prompt option is specified for an API application (does not apply toMac OS X), the key password must be provided by the application using theAPI in the dsmInitEx function call. The API itself does not issue a prompt tothe user but relies on the application to prompt the user as necessary.Restriction: This option can only be used by the root user or a Tivoli StorageManager authorized user.generateAn encryption key password is dynamically generated when the Tivoli StorageManager client begins a backup or archive. This generated key password isused for the backups of files matching the include.encrypt specification. Thegenerated key password, in an encrypted form, is kept on the Tivoli StorageManager server. The key password is returned to the Tivoli Storage Managerclient to enable the file to be decrypted on restore and retrieve operations.ExamplesOptions file:encryptkey promptCommand line:Does not apply.ErrorlogmaxThe errorlogmax option specifies the maximum size of the error log, in megabytes.You must be an authorized user to use the errorlogmax option.If you change from errorlogmax to errorlogretention, all existing log entries areretained and the log is pruned using the new errorlogretention criteria.If you change from errorlogretention to errorlogmax, all records in the existing logare copied to the pruned log dsmerlog.pru, the existing log is emptied, and loggingbegins under the new log wrapping criteria.If you change the value of the errorlogmax option, the existing log is extended orshortened to accommodate the new size. If the value is reduced, the oldest entriesare deleted to reduce the file to the new size.Chapter 10. Using processing options 309
