This parameter is optional. Specify this option, if you want to perform either a
ZDB to disk or a ZDB to disk+tape and leave the replica on a disk array (after
the backup session) to use it in future for instant recovery. If this option is not set,
it is not possible to perform instant recovery from the replica created in this
backup session.
Note that when this option is selected, the options -snapshot_type clone
and -snapshot_policy strict are automatically set by Data Protector. If
the option -snapshots number is not specified, it is set to 1.
-snapshots number
This parameter is optional. By default, Data Protector automatically sets this
option to 1 if the -instant_recovery option is specified.
Specify this option if you wish to keep the replica on a disk array after a backup
session is completed. With number, specify the number of replicas you want to
keep on a disk array. During every backup session, Data Protector creates a
new replica and leaves it on a disk array as long as the specified number is not
reached. When the specified number is reached, Data Protector deletes the oldest
replica and creates a new one.
The maximum number for vsnaps and standard snapshots is 7. Data Protector
does not limit the number of replicas rotated, but the session will fail if the limit
is exceeded.
Note that this option sets the number of replicas in the replica set for a backup
specification.
-snapshot_type{standard | vsnap | clone}
This option instructs Data Protector to create one of the two types of HP
StorageWorks Enterprise Virtual Array snapshots during the backup session.
Setting standard creates snapshots with the pre-allocation of disk space.
Setting vsnap creates snapshots without the pre-allocation of disk space.
Setting clone creates a clone of an original virtual disk.
-snapshot_policy{strict | loose}
Specifies how Data Protector creates snapshots with regard to types of already
existing snapshots for the same original virtual disk.
When strict is set, Data Protector attempts to create snapshots of the type
selected by the -snapshot_type option. If some of the original virtual disks
used in the backup session already have existing snapshots of different type, the
selected type of snapshots cannot be used. Such a backup session will be aborted.
When loose is set, Data Protector creates snapshots of different type than
specified by the -snapshot_type option, when this would help to make a
successful session. For example, if you select standard snapshots to be created,
but Data Protector detects that standard snapshots cannot be created because
