XADM: Local Objects Will Backsync From Other Sites (190703)
The information in this article applies to:

This article was previously published under Q190703 SUMMARY
When you restore the directory to a computer, directory objects not
included in the restored directory are repopulated with updated entries by
other servers in the organization. This includes the latest objects or
entries that originated from the restored server, that were not on the
backup.
MORE INFORMATION
This process is called backsyncing. When the directory is restored from
backup, a special flag is set in the registry which tells the directory to
start backsyncing. At this point, the restored directory contacts all the
other directories it is aware of and requests for replication updates
starting at zero, but with the "backsync" flag set. This causes the other
directories to search their databases for all objects that were sent by the
requesting directory.
For example, if you create UserA on Server1, the object for UserA
replicates out to other sites. If Server1 goes down, and you restore from a
backup that was done before UserA was created, Server1 will backsync and
will get the UserA object back from a server which it replicates the object
to. This is not limited to the local site; Server1 may receive this object
from another site.
Note: The updates will not be sent from another site if a "delete" has been
issued for the Directory Replication connector or the object(s).
