7.6 Using Virtual Copies
7.6.1 Creating a Virtual Copy
This feature supports hot (online) and cold (offline) backup of a database instance or backup
of archive log destinations only.
Creating a virtual copy requires the primary host Oracle SID. Perform this function through the
menu, tool bar, and popup menu.
To create a virtual copy, perform the following procedure:
1 Select Virtual Copy Management from the navigation view.
2 Select Create Virtual Copy from the Virtual Copies pull-down menu.
3 Select the desired options (online backup, offline backup, backup datafile only, or backup
archive log dest only) from the dialog box.
◆ Online (Hot) backup - The involved database instance must be up for this operation.
All tablespaces are put in backup mode before the virtual copy is created. After the
virtual copy creation is completed, tablespaces are taken out of backup mode.
◆ Offline (Cold) backup - The involved database instance must be down for this
operation.
◆ Backup datafile only - The involved database instance must be up for this operation.
All tablespaces are put in backup mode before the virtual copy is created. After the
virtual copy creation is completed, tablespaces are taken out of backup mode. This
backup only takes a virtual copy for all datafiles; not archive log destination. A virtual
copy created with the
-o datafile option is only useful when archive logfiles
generated during the creation of the virtual copy are also available. You may want to
create separate virtual copies using the
-o archonly option.
◆ Backup Archive Log Dest Only - The involved database instance must be up for this
operation. The database is forced to switch logs before a virtual copy of archive logs is
created.
