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.

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.

ob> mksnap --host lucy --fs /vol/vol0 lucy_snap
ob> lssnap --long lucy_snap
File system /vol/vol0:
    Max snapshots:          255
