Copy Properties - Advanced

Use this dialog box to select the backups that will be verified on a storage policy copy when a data verification operation is run; and to configure the data encryption properties for the storage policy copy.

Data Verification

  • Jobs
    • All Jobs

      If selected, all backups on this copy will be verified when a data verification operation is run.

    • All Full Jobs

      If selected, only full backups on this copy will be verified when a data verification operation is run.

    • Jobs on or After Date

      If selected, only the backup data after the specified date will be verified on this copy when a data verification operation is run.

    • Select a Date

      Select a date from the list.

  • Expiration
    • Verification expires after n month(s)

      Select the number of months for which the data verification will be valid.

Software Compression

  • Enable software compression on clients

    Select this option to enable software compression on all the clients associated with this storage policy copy.

Encrypt Data (displayed in primary copies)

Data Encryption Algorithm

  • Cipher

    Displays the ciphers available for data transfer.

  • Key Length

    Displays the key lengths available for the selected cipher. Note that the key length options displayed will vary according to the selected cipher.

When the Always enable encryption on new copies option is enabled in Media Management Configuration: Service Configuration tab, software encryption (using Blowfish with Key Length 128) is enabled in the primary copy, even if the encryption setting is not selected explicitly during the storage policy creation process.

Data Encryption (displayed in secondary copies)

Note: The Preserve encryption mode as in source, Re-encrypt data using selected cipher, and Store plain text options are applicable only for secondary copy.

  • Preserve encryption mode as in source

    If selected, data will be copied with the existing cipher that is configured on the client to encrypt the backup data.

    By default, this option is enabled.

  • Re-encrypt data using selected cipher

    If selected, data to be copied during Auxiliary Copy operation will be re-encrypted with the cipher selected in the Cipher list.

  • Store plain text

    If selected, the backup data will be decrypted and then stored as a plain text on the secondary storage.

    • Encrypt on network using selected cipher

      If selected, during Auxiliary Copy operation, the data will be encrypted on the network with the selected cipher from the Cipher list, and then stored as a plain text on the secondary storage.

  • Data Encryption Algorithm
    • Cipher

      Displays the ciphers available for data transfer.

    • Key Length

      Displays the key lengths available for the selected cipher. Note that the key length options displayed will vary according to the selected cipher.

  • Direct Media Access (External Restore Tools)
    • Via Media Password

      Data Encryption keys are stored scrambled on the media.

    • No Access

      Data Encryption keys are not stored on the media.

Throttle Network Bandwidth (MB/HR)

Specifies whether backup throughput is controlled. When selected, use the space to specify a value for the throughput. By default, the value is set to 500 megabytes per hour. The minimum value is 1 and there is no limit to the maximum value; however, the backup throughput is restricted to the maximum bandwidth on the network. This option can be used to reduce (control) the backup throughput so that the entire network bandwidth is not consumed. Increasing this value increases the bandwidth consumption. Note that traffic is throttled on a per-network-agent basis.

When setting up throttling for auxiliary copy operations, if the source and the destination MediaAgent are same, then you must configure the ThrottleLanFreeSDT additional setting to honor the values set for Network Bandwidth Throttling. For more information on configuring an additional settings see, Add or Modify an Additional Setting.
