Creating a destination baseline using a tape backup

You can perform a baseline transfer from local tape copies to a SnapVault secondary volume to manage your bandwidth or timing constraints over a network.

Before you begin

About this task

This operation physically copies data from tape to one or more secondary volumes. When the operation finishes, the secondary volume contains all the Snapshot copies that existed on the primary volume at the time the tape copy was created.

Steps

  1. Create a copy of the primary volume on the tape by using the system smtape backup command.
    For information about backing up and restoring from tape, see Performing tape seeding using SMTape.
  2. Restore the data to the empty secondary volume from the tape copy.
    For information about backing up and restoring from tape, see Performing tape seeding using SMTape.
  3. Initialize the SnapVault relationship by using the snapmirror resync command with the -typeXDP parameter on the secondary volume, and enable incremental updates.
