For multiple-server trees, if you are using the Backup eMTool to back up a server, you should
upgrade all the servers that share replicas with it to eDirectory 8.5 or later.
The restore verification process is backward compatible only with 8.5 or later. For more
information about the restore verification, see
“Overview of How the Backup eMTool Does a
Restore” on page 416
and
“Restore Verification Is Backward Compatible Only with eDirectory
8.5 or Later” on page 424
.
(NetWare
®
only) Review the issues with file system rights in
“Preserving Rights When
Restoring File System Data on NetWare” on page 424
. Test for potential problems and take
preventive action if necessary.
Periodically check the backup log file to make sure that unattended backups were successful.
Do a cold backup before upgrading a server, as described in
Section 18.9, “Upgrading
Hardware or Replacing a Server,” on page 557
.
For multiple-server trees, ensure that all eDirectory partitions are replicated on more than one
server, for fault tolerance.
In addition to making objects available when a server is down, such as during maintenance,
replicating your partitions also provides fault tolerance in a case where you lose a server, such
as a hardware failure. If a server in a multiple-server tree holds a partition that is not replicated,
and the server has a failure, there's a risk that you might not be able to recover the partition. It's
best to make sure all partitions are replicated. For more information on why you might not be
able to recover an unreplicated partition in a multiple-server tree, see
“Overview of How the
Backup eMTool Does a Restore” on page 416
,
Section 16.3, “Using Roll-Forward Logs,” on
page 425
, and
Section 16.9, “Recovering the Database If Restore Verification Fails,” on
page 462
.
For information on replication, see
Section 1.6, “Replicas,” on page 54
and
Chapter 5,
“Managing Partitions and Replicas,” on page 129
.
Ensure that the backup tapes containing the eDirectory and file system backups are in a safe
location.
Regularly test your backup strategy to make sure it meets your goals.
(Optional) If you plan to access servers remotely to do cold backups (a full backup with the
database closed) or to do advanced backup and restore tasks, install the eMBox Client on the
machine you plan to use. Also, arrange for access (such as VPN access) behind the firewall.
iManager lets you do backup and restore tasks remotely, outside the firewall, but it does not
support cold backup and advanced tasks.
The eMBox Client is installed with eDirectory on the server, and you can also use it on
workstations with Sun JVM 1.3.1. For information on installing and configuring the eMBox
Client, see
Section 20.1, “Using the eMBox Command Line Client,” on page 577
.
To prepare for a disaster in which you lose multiple servers:
Address the issues listed above.
For multiserver trees, consider creating DSMASTER servers to help you prepare for the event
of a disaster.
See
“Using DSMASTER Servers as Part of Disaster Recovery Planning” on page 422
.
Regularly test your disaster recovery strategy to make sure it meets your goals.
