The Erase Data feature allows you to permanently erase any data that was
archived.
This is useful if you want to erase data so that it cannot be recovered again.
For example, you may want to erase archived data for legal purposes or compliance
regulations.
Keep in mind that the erase data operation only erases the archived data -
the
source data will remain on the local hard drive. Therefore, it is recommended to delete
the data from the source first so that it will not be archived again.
The Erase Data operation makes the data inaccessible for browsing and
recovery - the data will remain on the media and take up space until it is aged
off according to the retention rules set for the data. Data will not be
recoverable using any data recovery methods. If the archive job
is already content indexed, the data being erased will be removed from the
index.
If stubs are erased, it may take up to one hour for the
erase data cache to be erased. Therefore, a recall operation may
succeed during that time. Once the erase data cache is refreshed
on the CommServe, stub recalls will be blocked for the data that
has been erased.
Using Erase Data, you can erase
data such as Linux, AIX, HP-UX, files.
To erase data, a filter storage policy needs to be associated with the Agent.
Ensure that the filter storage policy that you associate with the agent has
retention criteria that is greater than or equal to the retention criteria of
the storage policy for the data to be erased.
1.
From the CommCell Browser, right-click the appropriate agent icon
and then click Properties.
NOTES
Your screen may look different from the example shown.
2.
From the Storage Device tab of the agent Properties dialog box, select a filter storage policy from the Filter Storage Policy list.
To erase data, the storage
policy assigned to the subclient where data will be erased needs permission to allow
the erasing of data. Ensure that the retention criteria of the storage
policy for the data to be erased is equal or greater to the filter storage
policy that is associated with the agent.
1.
From the CommCell Browser, right-click the storage policy you want to
allow for the erasing of data, then click Properties.
2.
From the
General tab of the Storage Policy Properties dialog box, select the Allow
Erase Data
check box.
After the configuration has been completed, you
can now browse and erase data.

The Find feature allows you to search and locate data such as files,
directories, and messages in a backup. Once located, this data can be erased.
After erasing the data, it can no longer be browsed or
restored. However, the data will remain on the media and take up space until it
is aged off according to the retention rules set for the data.
Keep in mind that the erase data operation only erases the backup data -
the
source data will remain on the local hard drive. Therefore, it is recommended to delete

information about the job, such as the following:
Items that failed during the job
Items that succeeded during the job
Details of the job
Media associated with the job
Events of the job
Log files of the job.
This information can be viewed in the Job History window. The history provided depends on the entity from which the job history is viewed.
For example, viewing job history from the subclient level will yield information
for the jobs performed for that subclient. Conversely, viewing job history from
the instance level will yield information for jobs run from all subclients within
that instance.
To view the backup job history:
From the CommCell Browser, right-click the entity (client computer,
iDataAgent, instance, or subclient)
whose backup history you want to view, click View, and then click
View Job History.
From the Job History
filter window select the filter options, if any, that you want to apply, and
then click OK. The system displays the
