Virtual TapeServer 8.3 Configuration Guide

92 | Virtual TapeServer Configuration Guide
Be careful when defining attributes if multiple policies trigger the same action for the same
pool. Attributes for existing policies are overwritten (for policies that trigger the same action
for the same pool.)
7. Enable the policy if you want VTS to begin evaluating events and trigger policy actions. You
can leave the Enable checkbox unchecked if you want to leave the policy disabled for now.
8. Click the Save button.
Now, verify that jobs are configured and the Trigger Policy If Enabled attribute is set.
Managing virtual tapes
This section describes how to perform actions on virtual tapes:
l Creating virtual tapes
l Inserting virtual tapes into a VTL
l Mounting and unmounting virtual tapes
l Encrypting and decrypting virtual tapes
l Exporting virtual tapes
l Restoring data
l Erasing and deleting virtual tapes
l Managing locks on virtual tapes
Note If an unexpected power loss or shutdown occurs, data may not be written to virtual tapes that
were mounted. It is recommended that you rerun jobs for virtual tapes that were mounted
during the power loss or shutdown, to ensure that data is written to the virtual tapes as
expected.
Creating virtual tapes
You must create a virtual tape before the host server can mount and write data to it. When you
create a virtual tape, a file is created on the VTS server’s disk. The file is empty except for up to
27MB of header information (metadata), which is used by VTS to retain an audit trail of information,
including the following:
l Tape label information, such as the volume label
l When the virtual tape was created, written to, updated, mounted, unmounted, or erased
l If and when the virtual tape was exported, imported, migrated, or restored
l How long the virtual tape has been retained
l The ID of the key used to encrypt the tape, if Data Encryption is enabled and the tape is
encrypted
