Bette backup / restore functionality

We run a JIRA setup with 400+ users and 300+ projects in two different instances of JIRA (two different languages).

In a future version of JIRA it would be nice to see a better backup / restore funktionality than the existing one. Today it is only possible to backup or restore everyting.

I have two problems:

1. If a user deletes one or more issues in a projekt, there is no way i can restore these issues. Even though i take 2 daily backups of JIRA. Right now the backup is only usefull if we have a complete crash.

2. There is no way to move a projekt or just a bunch of issues from one JIRA instance to another.

What i would like to see:

An option to only restore a part of a backup (say one project). This project should be restorable to an existing project or to a new project. If imported to a new project it should be possible to bulk-move the issues to the right projekt. This would make it possible to do some advanced search and thereby restore individual issues. This would make many things easier.
