Restoring eDirectory and the File System
The only way to ensure that your eDirectory database can be fully restored is
through partition replication, with replicas of the entire database on multiple
servers.
On a single-server network, you need to rely more heavily on backing up the
data because you do not have replicas to restore information.
If part of the eDirectory tree structure, including partitions and replicas, exist
when the eDirectory database information is restored, those partitions and
replicas will be restored also, and you will not need to repartition the tree.
In case of corrupted data, follow these general steps:
1. Delete the corrupted eDirectory data.
2. Allow time for the deletion to propagate throughout the network. The
allotted time depends on the size of the data to be backed up, the size of
your network, the number of servers you have, and the number of
containers and users you have.
3. Restore the eDirectory data.
A replica containing the object does not have to be on the server. The
eDirectory database creates external reference when necessary.
NOTE: An external reference is a pointer to an eDirectory object not found locally
on the server; it is used to authenticate and reference objects that are not local to
the server.
There are specific recovery procedures for the following scenarios:
“Loss of a Volume Other Than SYS:” on page 35
“Loss of the SYS: Volume or an Entire Server” on page 35
“Loss of the Entire eDirectory Tree” on page 37
Loss of a Volume Other Than SYS:
Loss of a volume other than SYS: does not affect eDirectory. The only
requirement is to restore the file system data and trustee rights.
Loss of the SYS: Volume or an Entire Server
A hard disk failure involving the SYS: volume affects the entire server and
halts all NetWare operating system activities. Because the eDirectory files are
