Browse
provides an easy-to-use convenience to search and restore data.
You can open
the browse window from client, agent, instance or subclient level. The sub levels displayed
in the browse window is based on where you start the browse operation.
The browse window displays objects and consists of two parts:
The left pane displays the object tree at the selected
level.
The right pane displays the contents of the selected object.
Note that the window displays only the data that was obtained by a backup. Data
that is excluded by a filter, or data which did not exist as of the
specified browse time does not appear in the window.
Selections follow these rules:
All
selections are recursive.
Clicking a box again causes the selection to be cleared.
If you select an object in the left pane, then all of its contents are selected.
You can select a specific object in the right pane.
Selection status is revealed by the selection icons as follows:
Indicates that the object is not selected for restoration.
Indicates that a portion of the object is selected for restoration.
i.e., only some of the child object(s) within the selected object.
Indicates that the entire object, including all of its
child objects, are selected for restoration.
The option to browse the backup data provides the facility to view and
restore the data that was backed up. The following sections
explain how to browse the backup data.
By default, when a browse operation is requested, the software attempts to
browse from the storage policy copy with the lowest copy precedence. If the data
that you want to browse was already pruned from the primary copy, the software
searches the other copies of the storage policy, starting from the copy with the
lowest copy precedence to a copy with the highest copy precedence.
This feature is useful in the following conditions:
The media containing protected data for a particular copy has been
removed from the storage library, you can choose to browse from a copy whose
media are inside the library.
Allows browsing from a copy that accesses faster disk media rather than
slower tape media.
When media drives used by a particular copy are busy with another
operation, this helps in browsing from a different copy to avoid resource
conflicts.
From the CommCell Browser, navigate to Client Computers |
<Client> | Oracle
Right-click a Instance and click
All Tasks | Browse/Browse Backup Data.
From the
Browse Options dialog box, click Advanced.
In the Advanced Browse Options dialog box select the Browse from copy
precedence option.
If you specify a copy precedence number for a browse operation, the software
searches only the storage policy copy with that precedence number in all storage policies
used for securing the data. If data does not exist in
the specified copy, the browse operation fails even if the data exists in
another copy of the same storage policy.
Specify the precedence number in Copy Precedence.
Click OK in the Advanced Browse Options dialog box.
List media option is useful to predict media required to restore the index
required to browse data. This is useful when the index is not available in the
index cache.
The following section describes how to perform this operation.
From the CommCell Browser, navigate to Client Computers |
<Client> | Oracle
Right-click a Instance and click
All Tasks | Browse/Browse Backup Data.
From the Browse Options dialog box, if required, select the following
options:
Click Browse the Latest Data to list media associated with the
most recent data protection cycle.
Click Specify Browse Time to list media associated with data
protection operations up to the specified date and time range. Use the
Browse Data Before box to specify the end date and time.
Click Advanced and then click Exclude Data Before and
then select the date and time from which you wish to list media associated
with data protection operations.
Click List Media.
From the List Media dialog box, select the media you wish to
recall and click Recall Media.

Image browse displays the structure of the entity as it existed as of some
specified time. When you browse data in the image mode, the system by default
returns the requested data based on the latest image available. The image browse
can only restore the latest version. If the requested version was deleted before
the most recent full backup, the default browse will not find the data.
The no-image browse is useful for retrieving data that may have
been deleted at some unknown time. It is also useful to retrieve a previous
backup version.
From the CommCell Browser, navigate to Client Computers |
<Client> | Oracle
Right-click a Instance and click

This option displays the backup data as database tables of each user
in a tree view during the browse operation and allows selecting multiple
tables to restore them to a destination location.

In order to browse and restore the database
tables, you must run a full backup of the entire database
with the Enable Table Browse option enabled at the Subclient
level.
Data can be restored from any compatible library and drive type in the
CommCell. By default, the system automatically identifies and restores data from
any configured library in the CommCell, even if the media is not available in
the original library in which the data protection operation was performed. Use
this procedure to Browse using a specific MediaAgent.
From the CommCell Browser, navigate to Client Computers |
