Synchronizing the Primary and Backup Databases
The next examples of BACKUP and RESTORE commands show how to copy all files
from the primary system volumes $DATA01, $DATA02, $DATA03, and $DATA04 to
the magnetic tape device named $TAPE and how to restore these files to volumes of
the same name on the backup system. Note that you must include the AUDITED
option in both the BACKUP and RESTORE commands.
BACKUP $TAPE,($DATA01.*.*,$DATA02.*.*,$DATA03.*.*,
$DATA04.*.*), AUDITED
RESTORE $TAPE,($DATA01.*.*,$DATA02.*.*,$DATA03.*.*,
$DATA04.*.*), AUDITED
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/MP tables and Enscribe files: a NonStop SQL/MP 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/MP catalog, you must copy all partitions
of a NonStop SQL/MP 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.
Note. For this copy operation to work correctly, do not specify the SAVEALL option in the FUP
DUP command.
