You can enable encryption on the target media to have previously unencrypted archive files encrypted on the new media.

Archiver supports shutdown during a transfer operation; on the next restart, the transfer is resumed from the shutdown point.

To accelerate media transfers, you can split large jobs into smaller parallel tasks by assigning each to a separate media drive with a distinct date range. This approach allows multiple drives to process different segments of the archive at the same time, which improves transfer performance by 3–4 times.

Example: Split a 10-year archive into 10 jobs, one per year.

• Once the Archiver detects the source media, it begins the transfer.

• To re-process removable media, you must eject that media and insert another one. Once the Archiver begins the transfer from the second media, stop the Archiver service. Insert the original media and restart the Archiver service. Archiver will recognize that the source has changed and will begin to process that media.

• Contact Support for help re-processing fixed media.

• An Override Retention Settings check box becomes available when you change the Drive Mode of a drive to Transfer drive.

• If you do not select the Override Retention Settings check box, the transferred data retains the expiry that was configured for it at the time the data was originally archived.

• If you select the Override Retention Settings check box, the Retention Period settings become available in the user interface. Use the Retention Period settings to specify a new expiry value for the transferred data.

• Define any fixed media to be used in the process.

• Define the source drive as an archive drive in Replay drive mode. It is insufficient to merely disable the write capability or otherwise cause the drive to go into Replay mode. If the source drive is operating in any other Drive Mode, it will not be available as a source for the migration.

• Define the destination drive as an archive drive in Transfer drive mode. Include in the drive definition the association to the source Replay drive.

1. Define the fixed media to be used: 

   From Recording Management. find the Campaigns group and select Archive Media.

2. Define the source drive:

   1. In Recorder Manager, go to Archive > Drives.

   2. Select Create.

   3. Select the type of drive for the source drive.

   4. For Drive Mode, select Replay drive.

   5. Complete the rest of the drive definition as appropriate for the drive. 

      For instructions, see "Archive drive settings", in the Related Topics that follow.

3. Define the target drive:

   1. Select Create.

   2. Select the Drive Type for the target drive.

   3. For Drive Mode, select Transfer drive.

   4. As the Source Drive Name, use the drop-down to select the Replay drive that contains the source data.

   5. Complete the remaining drive definition as appropriate for the drive. All other transfer drive settings (encrypt contents, content type, and similar) apply and affect how data is written to the destination media.

      • If the transfer drive type is Hitachi HCP, the Hitachi HCP Retention Class setting is unavailable.

      • If the transfer drive type is EMC Centera, the EMC Retention Class/Period setting is unavailable.

      • To have previously unencrypted data encrypted during the transfer process, enable Encrypt Contents.

      • To speed up media transfer using date-based parallel processing, configure the Media Transfer Drive:

        1. Select Transfer by date (all day).

        2. In From, choose the start date for the transfer. Transfers start at 00:00:00 on the selected day.

        3. Optional. In To, choose the end date for the transfer. Transfers include data up to 23:59:59 on the selected date. If left blank, all data from the "From" date onward is included.

        As a safeguard, overlapping date ranges for the same source-destination pair are blocked to prevent duplicate transfers.

4. Save the new drive settings.

   After saving the drive settings, the system updates the archiver service with the new drive information.

Once the transfer begins:

• If the source media (such as a SAN) is larger than the destination media, multiple destination media need to be swapped in order to complete the transfer.

• If the source media is smaller than the destination media (such as a SAN), multiple source media need to be swapped in order to complete the transfer.

You can track the progress of the transfer through the Status page, found under the Operations area of Recorder Manager. The counters present on that page are updated. The values in the Current Archive Point and the Last Call fields move as the transfer progresses.

When the transfer from the source media is complete, Archiver raises an ArchiveTransferComplete alarm. If multiple source media are being transferred, eject the first source media and insert a second one. Archiver automatically begins to transfer from source to destination media as soon as it detects available media present in the source drive. The ArchiveTransferComplete alarm is cleared when the new transfer begins.

Fixed source media behave in the same way as removable source media, except that there is nothing to eject. The transfer operation automatically pulls all files from the source media. Note that this may be a very large number of files, depending on the size of the source SAN, FTP, Amazon S3, or Centera.

All other normal archive error handling and alarming mechanisms also apply to output activity on the destination media.
