This section describes the commands and the options to use volume based SnapRestore.

-vbsr option is added in snap restore CLI to select volume based SnapRestore. Use the following command syntax to perform restore using volume based SnapRestore:

snapdrive snap restore {-lun | -dg | -vg | -hostvol |
-lvol | -fs |-file} file_spec [file_spec ...] [{-lun | -dg |
-vg | -hostvol | -lvol | -fs -file} file_spec [file_spec ...]
...] -snapname snap_name [-force [-noprompt]][{-reserve |
-noreserve}]
[-vbsr [execute | preview]]

If no argument is supplied with the -vbsr, the default output is that of the preview option. A -verbose option is used which enables detailed output of all the mandatory checks that can be over-ridden by the user. The default output when -verbose option is not provided displays the results of the checks that is failed.

If you do not want any confirmation message to prompt, while executing volume based SnapRestore, you can use -noprompt and -force option with snap restore -vbsr execute command. The following table describes SnapDrive for UNIX behavior depending on the options provided by you.
