Redmine

Hi Redmine experts,

I have accidentally deleted an user account. All the issues related with this user is now showing as 'Anonymous'.
Since many updates has been done after deletion of user account, I am not in favour of restoring from available full mysql dump.
Is it possible to restore only the user account information without disturbing other updates??

Following are the details
Environment:
Redmine version 2.1.0.stable
Ruby version 1.8.7 (i686-linux)
Rails version 3.2.8
Environment production
Database adapter MySQL
OS: Ubuntu 12.04.1 LTS
MySql Version: 14.14 Distrib 5.5.35

Any help is appreciated!!
