Backup and Restore Solutions
Depending on the data to be backed up, three data backup
solutions are provided for the M2000
Dynamic data backup: backs up the dynamic service data of the
M2000 system
Static data backup: backs up the M2000 server application software,
database application software, database device files, and M2000
configuration files
System data backup: backs up the system data of the M2000 server,
such as operating system data, database application data, M2000
server application data

Typical Scenarios for Data Backup
The M2000 system is newly installed.
Backup of dynamic data (manually back up dynamic data to tapes)
Back up of static data
Backup of the operating system data
The M2000 program or database is upgraded, or the database is
expanded.
Backup of dynamic data (manually back up dynamic data to tapes)
Back up of static data
A patch of the operating system is installed.

Scenarios of M2000 Data Restoration
The M2000 system runs normally. It needs to roll back to the
historical operational status.
Restore dynamic data
The database device or the configuration files of the M2000 are
damaged. The operating system is still running properly.
Restore static data
Restore dynamic data
The operating system of the M2000 server cannot be started.

Set the Storage Device (From
Server) Ensure that the M2000 daemon process is started.
# daem_ps
Navigate to the /export/home/omc/var/etc/conf directory, and then
run the vi command to view the maintainsvc.xml file.
# cd /export/home/omc/var/etc/conf
# vi maintainsvc.xml
Search for the line <param name="backupMedia">, and then
change the disk for full backup and incremental backup to the actual
storage device.
<module name="all"> ... <param name="backupMedia">disk</param>
<module name="inc"> ... <param name="backupMedia">disk</param>

Set the Storage Device (From
Server) To back up dynamic data on a tape, specify the path of the
tape drive. Find the following lines:
<path name="backuppath">
<param name="tapePath">/dev/rmt/0</param>
Replace /dev/rmt/0 with the path of the tape drive
Run the following command to reload configuration
parameters.
# . /opt/OMC/svc_profile.sh
# svc_adm -cmd reload

Preparation for Data Restoration
If the M2000 service is running, stop it first.
# stop_svc
Ensure that the M2000 daemon process is started.
# daem_ps
Copy the backup files to a hard disk if the backup files are stored
on a tape. (Skip this step if the backup files are stored on a hard
disk)
Insert a tape into the tape and rewind the tape.
# mt -f /dev/rmt/0n rewind
Repeatedly run the following command until all the data on the tape is
copied to a hard disk:
# tar xvf /dev/rmt/0n

Restore M2000 Dynamic Data
Switch to user dbuser and restart the Sybase. Then, switch to user root.
# su - dbuser
Restart the Sybase
-bash-3.00$ exit
Restore the dynamic data.
# svc_backuprestore -cmd restore -s MaintenanceService
The following message is displayed:
******************************************************
* Restore is a dangerous operation ! *
* If you have to do it, please stop system first ! *

If the M2000 services and the Sybase are running, stop the
M2000 services and the Sybase.
Insert a tape into the tape drive, and then run the following
command to rewind the tape:
# mt -f /dev/rmt/0 rewind
Store the backup files in two tapes if one tape cannot hold the
backup files.

Preparation for Data Backup
Delete extra files if the backup is not performed immediately after
the initial installation of the M2000.
Delete the alarm dump files
# cd /export/home/omc/var/fm/dump
# rm -R /export/home/omc/var/fm/dump/event/*
# rm -R /export/home/omc/var/fm/dump/history/*

Backup M2000 Static Data
Back up the M2000 application
# cd /opt
# ufsdump 0ucf /dev/rmt/0n OMC
Back up the Sybase application.
# ufsdump 0ucf /dev/rmt/0n sybase
Back up the M2000 configuration files, the database application, and
the device files of the Sybase.
# cd /
# ufsdump 0ucf /dev/rmt/0n /export/home
NOTE: The device files of the Sybase are master.dat, sysprocs.dat, and
tmp_dev. The three files are stored in the path /export/home/sybdev.

Check after Data Backup
Check whether the static backup data on the tape is valid. If the static
backup data is backed up on multiple tapes, check the tapes one by one.
Rewind the tape.
# mt rewind
The contents of the first record on the tape are displayed.
# ufsrestore tf /dev/rmt/0n
The contents of the second record on the tape are displayed.
# ufsrestore tf /dev/rmt/0n
If the previous two records do not contain error information such as Media
read error: I/O error, you can infer that the data backup is valid.
Remove the tape from the tape drive.
Start the M2000 services and the Sybase.
