You may refer the procedure from the following post it had worked for many customers.

You can do a mass recall
You could initiate a mass recall using the advanced option in XP too 'Seach Tape Backup'
However if you are using placeholder you will have to run this as an admin user and ensure that you have the following regkey's set on the file server:
HKLM\software\kvs\enterprise vault\FSA\placeholderservice----
BypassrecallLimitsForAdmins = 1
RevertItemsToPlaceholders = 0 - This setting stops items from reverting back to a placeholder after 20 minutes.
Restart placeholder service for the settings to be effective.
If you are using XP SXP1/2, then right click on the folder in question through Window's Explorer and Search.
Then select advanced options on the right hand pane. You should have the option in there with a check box
that needs to be clicked. Just search for some text withing all the doc's.
An alternative is to use an Anti-Virus scan that does recall placeholders.
However if you are not using Placeholders this will not work for you and you would have to fall back on the PST method.
Also the next time you do an archive run it will reset the files back to placeholders if they fit your policy.
Also remember to reset the regkeys when you are done.
