16.2.8 Restore Verification Is Backward Compatible Only with
eDirectory 8.5 or Later
The restore verification process is backward compatible only with eDirectory 8.5 or later. If the
server you are restoring participates in a replica ring with a server running an earlier version than
eDirectory 8.5, the restore log will show a -666 error (incompatible DS version) for that replica.
This does not indicate whether the replicas are out of sync; it merely indicates that the restore
verification was unable to compare the transitive vectors because the version of eDirectory was
earlier than 8.5.
By default the database will not open because the restore verification was not completely successful.
However, you can use your best judgement in this case; if the only error was from an 8.5 server, and
the other servers verified successfully, it might be safe to open the database, using the override
restore option in the eMBox Client.
Another option might be to remove the server with the older version from the replica ring, and try
the restore again.
For more information about the restore process and transitive vectors, see
"Overview of How the
Backup eMTool Does a Restore" on page 428

Process" on page

16.2.9 Preserving Rights When Restoring File System Data on
NetWare
On NetWare only, restoring file system rights (also called trustee assignments) is dependent on the
object that is the trustee being present in eDirectory. Because of this relationship, you need to use
caution when restoring eDirectory and file system data on NetWare, to preserve file system rights.
If you restore eDirectory before restoring file system data, file system rights should be preserved
when file system data is restored. However, you should be aware of the issue. Test for potential
problems and take preventive action if necessary.
Why a Restore Could Potentially Affect File System Rights
As part of your preparation to restore eDirectory, you need to do a new installation of eDirectory
creating a new temporary tree, either on a new storage device to replace a failed one that held
volume sys:, or on a new machine if you are migrating a server from one machine to another.
A brand-new installation of eDirectory will not contain the objects that trustee rights have been
assigned for. (Of course, the objects will be restored when eDirectory is restored.)
When file system data is restored, the file system restore looks for the trustee objects in eDirectory.
If an object which is a trustee does not exist in the eDirectory database (such as in a new installation
before eDirectory has been restored), it's possible that rights assignments for that object might be
removed from the file system.
