Filter List View by User and Groups in SharePoint Does Not Work on site Restore to another Server

Question

We have a scenario where users from a group or seeing items of list views entered by users of other group.
For e.g, we have (ALL are Active Directory users and are authenticated as such)
GROUP A with USER-A1, USER-A2, USER-A3
GROUP B with USER-B1, USER-B2, USER-B3
GROUP C with USER-C1, USER-C2, USER-C3
We created views called
GROUP_A_VIEW
GROUP_B_VIEW
GROUP_C_VIEW
We created a web part for each of this view
And from Advanced Settings, added Target audience for each VIew with respect. For e.g. if Target AUdience is Group A, then USER-A1 will see items entered by himself or USER-A2, and USER-A3 but not the mbers of GROUP_B and GROUP_C
It works fine on the our development machine.
However when we backup and restore to other machine containing the same Active Directory users, 
GROUP A members are seeing records entered by GROUP B
GROUP B members are seeing records entered by GROUP C
GROUP C members are seeing records entered by GROUP D
....etc.
Any help will be appreciated.

Answer 1

Groups and users are stored locally in a cache on each site collection. Within that site collection they have IDs assigned which are used internally to identify those groups.
What is probably happening is that the groups you've targeted are being identified by IDs which are not consistent between your source site collection and your destination collection.
