NAME

NetApp::Snapshot -- OO class for creating and managing snapshots

SYNOPSIS

    use NetApp::Filer;
    use NetApp::Snapshot;

    my $filer   = NetApp::Filer->new( .... );

DESCRIPTION

This class encapsulates a single NetApp snapshot, and provides methods for querying information about the snapshot, as well as methods for managing it.

METHODS

get_parent

Returns the NetApp::Aggregate or NetApp::Volume object for the aggregate or volume for which object is a snapshot.

get_name

Returns a string representing the name of the snapshot.

get_date

Returns the date the snapshot was created.

get_used

Returns the percentage of space used by snapshot.

get_total

Returns the percentage of total space used by the snapshot.

get_snapshot_deltas

Returns an array of NetApp::Snapshot:Delta objects, each representing a single delta for this snapshot.

get_reclaimable

Returns the amount of reclaimable space, if the snapshot is deleted. Note that experimentally, this command has a lot of failure scenarios, most of which are reasonable (there are a lot of cases where you can't query this data). Therefore, unlike most of the methods in this API, it doesn't raise a fatal exception if it can't query the information, it simply generates warnings.

rename( $newname )

Renames the snapshot to the specified name.

restore( %args )

This method is an interface to the "snap restore" command. The argument syntax is:

    $snapshot->restore(
        type            => 'vol' | 'file', # Defaults to vol
        from_path       => $from_path,
        to_path         => $to_path,
    );

The 'type' argument maps to the -t CLI argument, and the 'to_path' argument maps to the -r CLI argument. Refer to the na_snap(1) man page, and the "snap restore" documentation for further information.
