mksnap

Purpose

Use the mksnap command to create a new snapshot. A snapshot is a consistent copy of a volume or a file system. Snapshots are supported only for Network Appliance filers running Data ONTAP 6.4 or later.

See Also:

"Snapshot Commands" for related commands

Prerequisites

You must have the right to manage devices and change device state to use the mksnap command.

Syntax

mksnap::=

mksn•ap [ --host/-h hostname ] [ --fs/-f filesystem-name ]
[ --nowait/-n ] snapshot-name ...

Semantics

--host/-h hostname

Specifies the name of an NDMP host. If you do not specify a host name, then Oracle Secure Backup uses the value from the host variable.

--fs/-f filesystem-name

Specifies the name of an NDMP file system. If you do not specify the --fs option, then the fs variable must be set.

--nowait/-n

Does not wait for the snapshot operation to complete.

snapshot-name ...

Specifies the name to give the new snapshot. Snapshot names must conform to the filename rules in effect where the snapshot is created.

Example

Example 2-93 creates a new snapshot of the file system /vol/vol0 on the NDMP host named lucy.
