Catalog Recovery Procedure for the Loss of an Entire Catalog

You should create a detailed disaster recovery plan to follow should it become necessary to restore your organization's data in the event of a disaster. A checklist of required tasks can be a tremendous tool in assisting associates in triage. For example, after the facility is safe for data to be restored, the power and data infrastructure need to be verified. When these tasks are completed, the following scenarios will help to quickly restore the NetBackup environment, and in turn, restore applications and data.

Disaster Recovery Procedure using the DR Image File

In the event of a catastrophic failure, use the following procedure to rebuild the previous NetBackup environment.

Note: If new hardware is required, make sure that the devices contain drives

capable of reading the media and that the drive controllers are capable of mounting the drives.

1. Install NetBackup.

2. Configure the devices necessary to read the media listed above.

3. Inventory the media.

4. Make sure that the master server can access the attached DR image file.

Start the NetBackup Recovery Wizard from the NetBackup Administration

Console. Or, start the wizard from a command line by entering

bprecover -wizard.

Disaster Recovery Procedure without the DR Image File

NOTE: ONLY ATTEMPT THIS AS A LAST RESORT If you do not have the attachment included with this email, use the following instructions to recover your catalog (If using OpenStorage disk pools, refer to the Shared Storage Guide to configure the disk pools instead of step 2 and 3 below ):

1. Install NetBackup.

2. Configure the devices necessary to read the media listed above.

3. Inventory the media.

4. Run:

bpimport -create_db_info [-server name] -id /home/storagemediag

5. Go to the following directory to find the DR image file

hotcatalog-backup_1276889431_INCR:

/usr/openv/netbackup/db/images/bksrvg/1276000000/tmp

6. Delete the other files in the directory.

7. Open hotcatalog-backup_1276889431_INCR file and find the BACKUP_ID

(for example: bksrvg_1276889431).

8. Run:

bpimport [-server name] -backupid bksrvg_1276889431

9. Run:

bprestore -T -w [-L progress_log] -C bksrvg -t 35 -p hotcatalog-backup -X -s 1276889431 -e 1276889431 /

10. Run the BAR user interface to restore the remaining image database

if the DR image is a result of an incremental backup.

11. To recover the NetBackup relational database, run:

bprecover -r -nbdb

12. Stop and Start NetBackup

13. Configure the devices if any device has changed since the last

backup.

14. To make sure the volume information is updated, inventory the media

to update the NetBackup database.

3.Configure VNC

4.Linux Tune Network Stack (Buffers Size) To Increase Networking Performance

By default the Linux network stack is not configured for high speed large file transfer across WAN links. This is done to save memory resources. You can easily tune Linux network stack by increasing network buffers size for high-speed networks that connect server systems to handle more network packets.

The default maximum Linux TCP buffer sizes are way too small. TCP memory is calculated automatically based on system memory; you can find the actual values by typing the following commands:

$ cat /proc/sys/net/ipv4/tcp_mem

The default and maximum amount for the receive socket memory:

$ cat /proc/sys/net/core/rmem_default

$ cat /proc/sys/net/core/rmem_max

The default and maximum amount for the send socket memory:

$ cat /proc/sys/net/core/wmem_default

$ cat /proc/sys/net/core/wmem_max

The maximum amount of option memory buffers:

$ cat /proc/sys/net/core/optmem_max

Tune values

Set the max OS send buffer size (wmem) and receive buffer size (rmem) to 12 MB for queues on all protocols. In other words set the amount of memory that is allocated for each TCP socket when it is opened or created while transferring files

# echo 'net.core.wmem_max=12582912' >> /etc/sysctl.conf

# echo 'net.core.rmem_max=12582912' >> /etc/sysctl.conf

You also need to set minimum size, initial size, and maximum size in bytes:

# echo 'net.ipv4.tcp_rmem= 10240 87380 12582912' >> /etc/sysctl.conf

# echo 'net.ipv4.tcp_wmem= 10240 87380 12582912' >> /etc/sysctl.conf

Turn on window scaling which can be an option to enlarge the transfer window:

# echo 'net.ipv4.tcp_window_scaling = 1' >> /etc/sysctl.conf

Enable timestamps as defined in RFC1323:

# echo 'net.ipv4.tcp_timestamps = 1' >> /etc/sysctl.conf

Enable select acknowledgments:

# echo 'net.ipv4.tcp_sack = 1' >> /etc/sysctl.conf

By default, TCP saves various connection metrics in the route cache when the connection closes, so that connections established in the near future can use these to set initial conditions. Usually, this increases overall performance, but may sometimes cause performance degradation. If set, TCP will not cache metrics on closing connections.

# echo 'net.ipv4.tcp_no_metrics_save = 1' >> /etc/sysctl.conf

Set maximum number of packets, queued on the INPUT side, when the interface receives packets faster than kernel can process them.

# echo 'net.core.netdev_max_backlog = 5000' >> /etc/sysctl.conf

Now reload the changes:

# sysctl -p

Use tcpdump to view changes for eth0:

# tcpdump -ni eth0

RUN following Commands

echo 'net.core.wmem_max=12582912' >> /etc/sysctl.conf

echo 'net.core.rmem_max=12582912' >> /etc/sysctl.conf

echo 'net.ipv4.tcp_rmem= 10240 87380 12582912' >> /etc/sysctl.conf

echo 'net.ipv4.tcp_wmem= 10240 87380 12582912' >> /etc/sysctl.conf

echo 'net.ipv4.tcp_window_scaling = 1' >> /etc/sysctl.conf

echo 'net.ipv4.tcp_timestamps = 1' >> /etc/sysctl.conf

echo 'net.ipv4.tcp_sack = 1' >> /etc/sysctl.conf

echo 'net.ipv4.tcp_no_metrics_save = 1' >> /etc/sysctl.conf

echo 'net.core.netdev_max_backlog = 5000' >> /etc/sysctl.conf

sysctl -p

4.how to increase ext3 filesystems performance ?

Ext3 & ReiserFS has three kinds of journaling methods

1)JournalDataWriteback
2)JournalDataOrdered
3)Journal Data

By default the the 2nd method is used.To speed things up we will make it use method 1. The price to pay is that it may allow old data to appear in files after a crash and journal recovery.

How to make ext3 or reiserfs use journal data writeback

First you need to take fstab file using the following command

sudo cp /etc/fstab /etc/fstab.orig

Edit the /etc/fstab file using the following command

sudo vi /etc/fstab

Add the thing marked in bold to your fstab root mount line.

/dev/hda1 / ext3 defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid,nouser,data=writeback 0 1

Save that file and exit

You need to take Grubmenu file backup using the following command

sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.orig

Now you need to edit the grub menu list file using the following command

sudo vi /boot/grub/menu.lst

look for the following two lines

#defoptions=quietsplash
# altoptions=(recovery mode) single

change to

#defoptions=quiet splash rootflags=data=writeback
# altoptions=(recovery mode) single rootflags=data=writeback

Save that file and exit

Now you need to update the grub using the following command

sudo update-grub

the added flags will automatically be added to the kernel line and stay there in case of kernel update

Changes to Ext3 FileSystem Only

Note:- tune2fs only works for ext3. Reiserfs can’t change the journal method

Before rebooting change the filesystem manually to writeback using the following command

sudo tune2fs -o journal_data_writeback /dev/hda1

Check that it is running or not using the following command

sudo tune2fs -l /dev/hda1

Remove update of access time for files

Having the modified time change you can understand but having the system updating the access time every time a file is accessed is not to my liking. According to the manual the only thing that might happen if you turn this off is that when compiling certain things the make might need that info.

To change this do the following

sudo vi /etc/fstab

add the following marked in bold

/dev/hda1 / ext3 defaults,errors=remount-ro,noatime,auto,rw,dev,exec,suid,nouser,data=writeback 0 1

Now reboot and enjoy a much faster system
