To back up storage groups to tape (where a tape backup management software that is unable to link
with Application Agent is used):
1.
When usual operation is in the split state, execute
EX_DRM_CACHE_PURGE
to clear the secondary
volume cache.
2.
When usual operation is in the split state, execute
EX_DRM_RESYNC
to resynchronize the copy
group.
3.
Execute
EX_DRM_EXG_BACKUP
to back up the file system to the secondary volume.
4.
Execute
EX_DRM_DB_EXPORT
to export the backup information to temporary files.
5.
Execute
EX_DRM_FTP_PUT
to transfer the temporary files to the backup server.
6.
Execute
EX_DRM_DB_IMPORT
to import the temporary files transferred from the database server
to the backup catalog on the backup server.
7.
Check the backup ID.
To check the backup ID, open the backup ID record file (operation-ID
.bid
) in the following
directory on the backup server:
FTP_HOME_DIR-value
\
FTP_SUB_DIR-value
\
operation-ID
\BK\
operation-ID
.bid
8.
Check the storage location of the data files.
To make this check, execute the
drmmount
command with the backup ID determined in step 7
specified as an argument.
The command results show the mounted drive name. The mounted drive contains the data files
(
*.edb
or
*.stm
), transaction log files (
*.log
), and checkpoint files (
*.chk
) of the storage
group. If necessary, execute the
drmexgcat
command to check the contents of the file to be
backed up.
9.
Use a tape backup management software to back up all the files in the mounted drive to tape.
10.
Execute the
drmumount
command to unmount the mount point mounted in step 8.
To restore a storage group from a tape (where a tape backup management software that is unable
to link with Application Agent is used):
1.
Execute the
drmexgcat
command to identify the backup ID for the backup catalog to be restored.
2.
Execute the
drmmount
command, and then restore the backup from tape to the storage location
checked in backup steps 7 and 8.
3.
Execute
EX_DRM_BACKUPID_SET
by specifying the backup ID to create a backup ID record
file.
4.
Carry out the procedures following step 4 described in “
” on page 419 to restore the backup from the secondary volume to the primary volume.
Backing up and restoring storage groups by using a file share
When backup information is transferred between a database server and a backup server, extended
commands (
EX_DRM_FTP_PUT
or
EX_DRM_FTP_GET
) are normally used to transfer the information
in an FTP operation. Instead of FTP, however, file sharing can also be used to back up and restore
storage groups. The following subsections describe examples of backing up or restoring
storage
groups
by using a file share.
