I've never done it, and don't like it, but subfile backup?

We have an operations and security team that is constantly either moving client data or changing a file spaces inheritable ACL's, which in turn results in the next backup recognizing this as "changed" or "new" data and backing it up again. This results in wasted storage and reduces the retention history. Can anyone tell me if there is a way to prevent this from happening or how they deal with these situations? For example; in the event of permission changes can TSM just update the existing backup data with the ACL changes and not re-backup the actual files/directories? I am regularly dealing with this on several clustered file servers that have about 10tb of data so when this happens the impact to storage is pretty intense. Unfortunately, most of the time I do not know the changes are taking place until the damage is done and then have to extend the time to investigate the cause so I can explain the space usage. All comments welcome and appreciated... ~Rick Adamson Jackonville,FL
