both the BACKUP and RESTORE commands.

Synchronizing Databases With FUP
You can use the FUP DUP command to copy Enscribe database files from the primary
system to the backup system. If you use FUP DUP, the “FUP ALTER filename , NO
AUDIT” command is performed implicitly for each backup file that corresponds to a
primary file protected by RDF. You will therefore need to turn the audit flags back on for
all the data volumes on the backup system after the FUP DUP operation is complete.
Synchronizing Partitioned Files
When synchronizing partitioned files, you must consider one major difference between
NonStop SQL tables and Enscribe files: a NonStop SQL catalog has a description of all
indexes of a table and partitions of a partitioned table, but a partitioned Enscribe file
has no associated catalog.
To ensure the consistency of a NonStop SQL catalog, you must copy all partitions of a
NonStop SQL table and its dependent indexes at one time rather than on a partition
basis. You can use either the SQLCI DUP command or the BACKUP and RESTORE
utilities to copy the partitions.
For an Enscribe file, you can use the FUP DUP command or the BACKUP and
RESTORE utilities to copy the individual indexes and partitions. Then use FUP ALTER
to incorporate the other partitions and any alternate indexes into the primary partition.
If the volume names for partitions on the backup system are different from the volume
names on the primary system, you need to change the volume references for those
partitions.
Backing Up Application Programs and Files
To enable the backup system to take over in the event of a primary system failure, you
need to put usable copies of all program files, OBEY command files, and other files
your applications use on the backup system. You can do this by using the Autosync
product. After copying these files, you might need to change names to reflect the
backup system’s naming conventions, and you might need to recompile some
programs.
Note. For this copy operation to work correctly, do not specify the SAVEALL option in the FUP
DUP command.
