* This class defines a Directory Server task that can be used to restore a
* backup.
*
*
* NOTE: This class, and other classes within the
* {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
* supported for use against Ping Identity, UnboundID, and
* Nokia/Alcatel-Lucent 8661 server products. These classes provide support
* for proprietary functionality or for external specifications that are not
* considered stable or mature enough to be guaranteed to work in an
* interoperable way with other types of LDAP servers.
*
*
* The properties that are available for use with this type of task include:
*
*
The path to the backup directory in which the backup resides. This
* must be provided when scheduling a new task of this type.
*
The backup ID of the backup to be restored. If this is not provided
* when scheduling an instance of this task, then the most recent backup
* in the backup directory will be selected.
*
A flag that indicates whether to attempt to restore the backup or
* only to verify it to determine whether it appears to be valid (e.g.,
* validate the digest and/or signature, make sure that the backend
* considers it valid, etc.).
*
The path to a file containing a passphrase to use to generate the
* encryption key.
