Managing Clerks, Servers, and Clearinghouses
• How recently the backup was created
• What modifications were made since that time
• Whether the backup included the clearinghouse files in the directory
dcelocal/var/directory/cds
If you decide to use operating system backups, you only need to back up the server
systems whose clearinghouses store master replicas of directories. To ensure that you
back up your namespace completely, check for the following:
• The servers on these systems are disabled by using the cdscp disable server
command.
• The files in the root directory dcelocal/var/directory/cds are included in the backup.
If your namespace is small enough to be maintained in one clearinghouse, you can
reliably use traditional operating system backups to save and restore the clearinghouse
data. If only one clearinghouse exists, only one replica (the master replica) of each
directory exists. This eliminates the need to account for the discrepancies that may exist
among multiple directory replicas. Remember that the more frequently you back up
clearinghouse data, the more up-to-date that information will be if you need to restore it.
