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.

Backup of the operating system data

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


The operating system of the M2000 server cannot be started.

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>

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

Page17

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 ! *

******************************************************

Continue ?[n/y]

Preparation for Data Backup

Back up the dynamic data.

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/*

Delete the core files

# cd /export/home/omc/var/logs

# rm core*

Delete the history trace files

# cd /export/home/omc/var/logs/tracebak

# rm iMAP*

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.


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.

If the M2000 services and the Sybase server are running, stop the M2000

services and the Sybase.

Check whether the raw volume or the disk raw partition used by the data

device functions well.

Insert a tape into the tape drive.

Check whether the static backup data on the tape is valid.

Rewind the tape.

Restore the M2000 application

# cd /

# rm -R /opt/OMC

# ufsrestore rf /dev/rmt/0n

Restore the Sybase application

# rm -R /opt/sybase


Restore the M2000 configuration files, the Sybase application, and the device files of the

Sybase

Start the Sybase as user dbuser.

Check the status of the database to make sure the status of

each database is not offline or not recovered.

-bash-3.00$ isql -Sdatabase server name -Usa -Pxxxxxx

1> sp_helpdb

2> go

Check the server before backup

View the IP address of the server

Check the system hardware

Check whether the root disks are properly encapsulated and mirrored

Check the log of the operating system

Run the explorer program

Check the status of the tape drive.
