Plug-in Options
How to set plug-in options
Plug-in options enable you to control specific actions for on-demand backups, restores,
and scheduled backups. The plug-in options that are available depend on the operation
type and client plug-in type.
You specify plug-in options for on-demand backup or restore operations or when you
create a dataset for a scheduled backup. You can set options by using the graphical
controls and by typing options and values in the Enter Attribute and Enter Attribute Value
fields.
No error checking or validation is performed on free text entries. In addition, free text
entries override settings made using the graphical controls.
Detailed instructions on how to access and set plug-in options during a backup or restore
are available in
“Backup” on page 73 and “Restore” on page 77 .
