1. Common commands for system backup and recovery

1. fbackup & frecover

1.1 System Backup command: fbackup

1) Common fbackup Method 1:

[1] accessing a single user:

# Shutdown-Y 0
#/Etc/Mount-

[2] Full System Backup

# Fbackup-F/dev/RMT/0 m-0iv/-I/tmp/sysbk. Index

-F: Device File Name (such as DDS tape driver)
-I: directory to be included
-E: excluded directory
-I: Backup Content Retrieval directory
-V: Detailed list of backup content
-0: Zero-level backup

# Fbackup-F/dev/RMT/0 m-I/-E/home

Back up all directories except/home

[3] Description

1) This command backs up the current "mounted" file system.
2) backup level description

Backup level: 0 ~ 9 levels. If the current system uses zero-level backup, the current system uses five levels at a time.
During backup, the system only backs up the changed files.

2) Common fbackup methods:

[1] # mkdir-P/tmp/fbackupfiles/Index
# Mkdir-P/tmp/fbackupfiles/log

# Touch/tmp/fbackupfiles/index/full. 'date' + % Y % m % d. % H: % m''

[3] accessing a single user

# Shutdown-Y 0
#/Etc/Mount-

Full backup of the system

# Fbackup-0vi/-F/dev/RMT/0 m/
-I/tmp/fbackupfiles/index/full. 'date' + % Y % m % d. % H: % m ''/
2>/tmp/fbackupfiles/log/full. 'date' + % Y % m % d. % H: % m''

In this way, you can know the time required for system backup.

3) Common fbackup methods:

[1] enter a single user

# Shutdown-Y 0
#/Etc/Mount-

Full backup of the system

# Fbackup-0uv/-F/dev/RMT/0 m/
-G/tmp/fbackupfiles/mygraph/
-I/tmp/fbackupfiles/index/full. 'date' + % Y % m % d. % H: % m ''/
2>/tmp/fbackupfiles/log/full. 'date' + % Y % m % d. % H: % m''

Instructions

A. File mygraph: contains the directory to be backed up. The format is as follows:

I/users/Data
I/home/APP
E/Oracle/SQL

B. parameter U:

When the backup system is successful, the system updates/var/adm/fbackupfiles/dates.

4) fbackup:

Back up remote systems

[1] When logging on to the local system

# Remsh backup_sysname "fbackup-F dds_sysname:/dev/RMT/0 m-0vi /"

[2] When logging on to a remote system

# Fbackup-F backup_sysname:/dev/RMT/0 m-0vi/

5) Common fbackup Methods 5:

Compression mode backup (not recommended, affecting system performance)

[1] Compression backup

# Fbackup-0vi/Dir-F-| compress | dd OF =/dev/RMT/0 m obs = 10 K

"-": Pointing to standard output

[2] viewing backup content

# Dd If =/dev/RMT/0 m IBS = 10 k | uncompress | frecover-I--f-

1.2 System Recovery command: frecover

1) Restore all content on the tape drive:

[1] accessing a single user:

# Shutdown-Y 0
#/Etc/Mount-

[2] Recovering data

# Frecover-RF/dev/RMT/0 m

Recover all data on tape

-F: Device File Name
-R: Restore all data on the tape
-I: index the files on the tape to the specified files.

# Frecover-I/tmp/index.txt-F/dev/RMT/0 m

2) restore a directory:

# Frecover-XI/directory

# Frecover-X-I/dir1-I/dir2

# Frecover-xoi/Dir

-O: overwrite existing files with the same name under/Dir

# Frecover-xvxi/Dir

-X: Restore data by directory on tape

# Cd/tmp/local; frecover-xvyi/Dir

-Y: Restore data by tape file name

For example:

# Cd/tmp/local
# Frecover-xvf-I/home/filename

[Recovery result]/tmp/local/filename is not/home/filename

3) recover data from the remote tape drive to the local device:

# Frecover-XI/Dir-F remote_name:/dev/RMT/0 m

4) recover data from the local drive to the remote system:

# Remsh remote_name "frecover-XI/Dir-F local_name:
/Dev/RMT/0m"

2. tar command

2.2.1 full system backup

# Tar CVF/dev/RMT/0 m/

2.2.2 back up a directory

# Tar CVF/dev/RMT/0 m/tmp

2.2.3 change the file backup path

# Tar CVF/dev/RMT/0 m-C/tmp.

[Note]: The Path/tmp is changed to the backup path on the tape ./

# Cd/tmp
# Tar CVF/dev/RMT/0 m ./*

2.2.4 data restoration

# Tar xvf/dev/RMT/0 m (all data on the tape)

# Tar xvf/dev/RMT/0 m/tmp (Restore directory/tmp)

2.2.5 view tape data

# Tar tvf/dev/RMT/0 m

1) back up all data on the system hard disk

Copyutil> Backup

Enter the disk index ([Q]/?) : 0
Enter the tape index ([Q]/?) : 2

Use Data Compression? (Y/[N])? Y

When backup finished, system will show: Done!

Copyutil> exit

3) recover data to the specified system hard disk

Copyutil> restore

Enter the tape index ([Q]/?) : 2
Enter the disk index ([Q]/?) : 0

Use Data Compression? (Y/[N])? Y

After system display: restored successful, that means restore is finished!

Copyutil> exit

4) Note:

When copyutil is used to back up the root disk to the corresponding tape, the tape can be used as a bootable tape.

5 make_recovery

1) install "Ignite-UX application"

[1] install from HP-UX application CD-ROM

1) # swinstall
2) "mark" [A. 1.53 HP-UX installation utility (Ignite-UX for 10.20)]
3) "analysis"
4) "Install"

[2] download and install from Website:

1) http://www.software.hp.com/
Select: "Network & System Administration"
Download: ignite-ux_10.20.tar (OS version 10.20)

2) install it on the hard disk:

# Cd/tmp
# Tar xvf/dev/RMT/0 m./ignite-ux_10.20.tar
# Swinstall-S/tmp/ignite-ux_10.20.tar

3) install on tape:

# Dd If =/tmp/ignite-ux_10.20.tar of =/dev/RMT/0 m BK = 2
# Swinstall-S/dev/RMT/0 m

[4] make_recovery:

#/Opt/ignite/bin make_recovery [-aprvc] [-D destination] [-B boot_destination]

-A: Specifies the root disk/volume group to be backed up.

-P: preview the backup process without creating bootable DDS tape.

A. Confirm the/var/opt/ignite/recovery/mkrec. append file.

B. Create the/var/opt/ignite/recovery/arch. Include File.

-R: After the-P option is used, you can use this option to create the bootable DDS tape.

A. This option recognizes the/var/opt/ignite/recovery/arch. Include File.

-V: displays the prompt information about the backup process.

-D: Specify the Device File Name of the DDS (default:/dev/RMT/0mn)

-B: Specifies the temporary files used during system backup (default:/var/tmp/uxinstlf. Recovery)
The file size is 32 MB. When make_recovery is performed on the system, note the/var file system.
When the/var file system is insufficient, use the following command to back up the system:

# Make_recovery-a-c-B/tmp/uxinstlf. Recovery

-C: create a file that reflects the current state of the system:/var/opt/ignite/recovery/makrec. Last

If the file exists, you can use the check_recovery command.

[5] Note:

The tapes backed up with make_recovery are bootable tapes that can be used to install OS.

2) backup system root disk

Ii. system backup/recovery methods and strategies

2.1 system backup policy

HP-UX core-OS:

This part of content mainly includes some HP-UX used in the file system, such as/,/OPT,/var,/tmp,/usr,/home,/stand usually these file systems are located in vg00.

Backup method:

(1) fbackup:

# Fbackup-0vi/-F/dev/RMT/0 m/
-I/tmp/fbackupfiles/index/full. 'date' + % Y % m % d. % H: % m ''/
2>/tmp/fbackupfiles/log/full. 'date' + % Y % m % d. % H: % m'

For details, see (Common fbackup method 2)

(2) make_recovery:

# Make_recovery-c-a-B/tmp/oslif. rec

For details, see (make_recovery)

[2] system configuration file

Some critical files or information of the system need to be backed up separately, which is conducive to system recovery. These files or information include:

(1) system swap information

# Swapinfo-T

(2) System File System Information

# BDF

(3) system I/O Information

# Ioscan-fncdisk

(4)/etc/fstab

(5) System Logical volume configuration file

/Etc/lvmconf/vg00.conf, v1_1.conf, and v1_2.conf

You can run the following command to configure these logical volumes:
Vgcfgbackup/vgcfgrestore generation and recovery

(6) use HP tools to collect and back up system configuration information

These tools include: lvmcollect.10
Collect. Sh
Capture. Sh
Collect. conf

Backup method:

(1) tar

# Tar CVF/dev/RMT/0 m./vg00.conf./v1_1.conf

(2) fbackup

# Fbackup-F/dev/RMT/0 m-I/etc/lvmconf/v1_1.conf

Other System Logical volumes (for example, vg01 and vg02)

Backup method:

(1) fbackup:

# Fbackup-0uv/-F/dev/RMT/0 m/
-G/tmp/fbackupfiles/mygraph/
-I/tmp/fbackupfiles/index/full. 'date' + % Y % m % d. % H: % m ''/
2>/tmp/fbackupfiles/log/full. 'date' + % Y % m % d. % H: % m''

(2) tar

# Tar CVF/dev/RMT/0 m/Oracle/APP/home/Oracle

[4] Database Backup

Refer to the database backup method

2.2 system recovery policies

When fbackup/tar is used to back up the system

1) install core-OS

2) restore the backup content of vg00, vg01, and vg02

# Frecover-o-r-F/dev/RMT/0 m

When you back up the system with make_recovery

1) use a tape boot system to restore vg00

For details, see the restoration method of make_recovery.

2) Restore other logical volumes

# Frecover-o-r-F/dev/RMT/0 m
