How to enable SMB Windows

The Server Message Block (SMB) Protocol is a network file sharing protocol, and as implemented in Microsoft Windows is known as Microsoft SMB Protocol. The Common Internet File System (CIFS) Protocol is a dialect of SMB. Both SMB and CIFS are also available on VMS, several versions of Unix, and other operating systems.

Although its main purpose is file sharing, additional Microsoft SMB Protocol functionality includes the following:

    Dialect negotiation
    Determining other Microsoft SMB Protocol servers on the network, or network browsing
    Printing over a network
    File, directory, and share access authentication
    File and record locking
    File and directory change notification
    Extended file attribute handling
    Unicode support
    Opportunistic locks


For security reasons, Microsoft recommends that you disable SMB1 immediately.

to enable on windows 10

go to control panel > programs and features > turn windows features on or off

and Scroll down to SMB 1.0/CIFS File Sharing Support

BACKUPPC INSTALLATION AND CONFIGURATIONS

BACKUPPC INSTALLATION AND CONFIGURATIONS

BackupPC is a backup solution that can be configured to back up remote Linux and Windows systems. It can use a variety of different protocols and has a flexible scheduler to coordinate full and incremental backups.

I have installed this on ubutnu 14.04 LTS and its running fine for me for a long time since the installation

Open a terminal and enter the following commands:

sudo apt-get update
sudo apt-get install backuppc


During the installation, you will be asked what kind of mail server configuration is needed. We can select the "Local only" option, because we will not be configuring internet-aware mail

                ???????????????????????????????????????? 

On the next page, we can leave the Sytem mail name as "localhost":

Now change the password for backuppc

htpasswd /etc/backuppc/htpasswd backuppc
Enter the password when prompted.

create an SSH key pair for BackupPC user called backuppc and then transfer this key to the client computers.

Type

sudo su – backuppc

Generate an SSH key pair:

ssh-keygen

You will be prompted for three questions. Just press Enter to accept the default values.

Now we have the key pair, we need to transfer the public key.

Transferring the SSH Public Key

On the client computer, make sure you have the following configured:
We need to enable root account for SSH access. To do that, edit the file /etc/ssh/sshd_config and comment the line:

#PermitRootLogin without password
Add the line:

PermitRootLogin yes
Then restart SSH:

service ssh restart.
Note: you do not need the following user configured, but for my convenience, I have added a login for my own testing later. Ignore the italic text below.

useradd chuong
passwd chuong
mkdir /home/chuong
chown chuong:chuong /home/chuong
Now copy the key to the client computer:

ssh-copy-id root@10.0.0.10 (note that 10.0.0.10 is another Linux system I want to work as a client machine).

SSH to root@10.0.0.10, you should be able to directly SSH to the client without having to supply a password for the user root. Verify that is the case.

Now type exit to close the connection to 10.0.0.10. Type exit again to exit the user backuppc and go back to the default currently logged in user.

Launch your browser and go to this URL:
http://10.0.0.12/backuppc.

Note: If for any reasons, the web page does not show up but it asks you to download a file that contains garbage characters in it (most probably happens in Ubuntu 14.04.1), you need to perform the followings to fix it:

rm /etc/apache2/conf-enabled/backuppc.conf
sudo ln /etc/backuppc/apache.conf /etc/apache2/conf-enabled/backuppc.conf
service apache2 restart

Then try again. When prompted for a credentials, use backuppc as the user name and the password you changed earlier.
Shown below is the main interface of BackupPC.

At this point /var/lib/backuppc is the default backuppc storage location and also the home directory of user backuppc.

Configure Client for Backup
We need to setup the client computer for backup. On the left hand side, click Edit Hosts.

 Now click Add to add the client host.

Enter the IP address of the client computer, the user name should be backuppc. Click Add when done.

 Enter the IP address of the client computer, the user name should be backuppc. Click Add when done.

 

Configure Transfer Method

We will use rsync to transfer. Now we will configure this setting.
Click Xfer tab. Under XferMethod, choose rsync. Under RsyncShareName, click Add to choose a directory to backup. You can leave it as “/” to backto the entire the computer if you want.

 

 I add /etc/ppp to backup. Note that if you choose to backup the entire computer (using /), you have to exclude the /proc and the /sys directories. For now, remove the / so that the entire system is not backed up. We just want to backup /etc/ppp. Click Save.

 

CLick Schedule to check the backup schedules. As you can see, by default, full backup happens every 6.97 days and incremental backup happens every 0.97 days. We can keep these settings as is.

 

Run backup Manually

Let’s run the backup manually instead of waiting for 7 days.
Click the Hosts tab and then click the Select a Host drop down list.

 

Click Start Full Backup

Click Start Full Backup to confirm.

The backup will happen and it

 

 The backup should finish shortly as there are only a few files in our demonstration. The backup is stored at: /var/lib/backuppc/pc/10.0.0.10/#_of_backup.

In the Web interface, click the link to go back to the home page.

Click on the backup job to see backed up files.

 

 As you can see, the directory /etc/ppp has been successfully backed up and the contents is stored on the backup server.

RAID Explained

RAID stands for Redundant Array of Inexpensive (Independent) Disks.

On most situations you will be using one of the following four levels of RAIDs.

    RAID 0
    RAID 1
    RAID 5
    RAID 10 (also known as RAID 1+0)

This article explains the main difference between these raid levels along with an easy to understand diagram.

In all the diagrams mentioned below:

    A, B, C, D, E and F – represents blocks
    p1, p2, and p3 – represents parity

RAID LEVEL 0

    Minimum 2 disks.
    Excellent performance ( as blocks are striped ).
    No redundancy ( no mirror, no parity ).
    Don’t use this for any critical system.
 
 RAID LEVEL 1

    Minimum 2 disks.
    Good performance ( no striping. no parity ).
    Excellent redundancy ( as blocks are mirrored )

RAID LEVEL 5

    Minimum 3 disks.
    Good performance ( as blocks are striped ).
    Good redundancy ( distributed parity ).
    Best cost effective option providing both performance and redundancy.
    Use this for DB that is heavily read oriented. Write operations will be slow.

RAID LEVEL 10

   
     

    Minimum 4 disks.
    This is also called as “stripe of mirrors”
    Excellent redundancy ( as blocks are mirrored )
    Excellent performance ( as blocks are striped )
    If you can afford the dollar, this is the BEST option for any mission critical applications  (especially  databases).

Backup Server on an Ubuntu 12.04 with BackupPC

BackupPC is a backup solution that can be configured to back up remote Linux and Windows systems.

It can use a variety of different protocols and has a flexible scheduler to coordinate full and incremental backups.

BackupPC is a powerful, user-friendly way to automatically backup files from several servers to a central location. Backups are essential for any kind of production environment. Just as important is making sure that file restoration operations function correctly.
There are many backup tools available for Linux and Unix-like operating systems. Choose the solution that fits your needs the best. BackupPC is a great tool that should work well in many developers' environments.

BackupPC is available in Ubuntu's default repositories.
The software "pulls" the data from client machines,
so the actual program needs to be installed on the machine that will function as the backup server.


The files will be stored at:

/var/lib/backuppc/pc/ip_address_of_client/#_of_backup 

Open a terminal and enter the following commands:

sudo apt-get update
sudo apt-get install backuppc

During the installation, you will be asked what kind of mail server configuration is needed. We can select the "Local only" option, because we will not be configuring internet-aware mail:

On the next page, we can leave the Sytem mail name as "localhost":

Select "apache2" to configure Apache for use with BackupPC:

type "Enter" to continue with the installation.
Changing the Password

BackupPC uses a system user called "backuppc" to perform its tasks.

In addition, it configures an Apache user, also called "backuppc", with a randomly generated password, which was given briefly during installation. We can change this password to something more meaningful by typing:

sudo htpasswd /etc/backuppc/htpasswd backuppc

You will be asked to give and confirm a new password.

Configure SSH Access to Client Computers

There are a few different ways that servers and clients can communicate to authenticate and transfer data. In this guide, we will be using the rsync protocol over SSH.

To make this work, we'll need to create an SSH key pair for our system BackupPC user (called "backuppc", as mentioned above), and then transfer the key to the client machines.

First, log into the BackupPC user with the following command:

sudo su - backuppc

You will probably be presented with only a minimal prompt, represented by the dollar sign ($).

Generate an SSH key pair by typing:

ssh-keygen
You will be asked a number of questions. Just type "Enter" through all of the prompts to accept the default values.

Transferring the SSH Public Key

You now have a private and public key on your backup server. You need to transfer the public key to the root user on each client machine you wish to access.

You can do that by typing:

ssh-copy-id root@client_ip_address

Type "yes" to accept the new server's identity, and then enter the root password of the remote machine. The key should then be transferred.

Check that your key was transferred correctly by typing:

ssh root@client_ip_address

You should be able to log in without having to type a password.

Get back to the BackupPC server by typing:

exit

Back out of the "backuppc" account by typing "exit" again:

exit

Access the Web Interface

The rest of the guide will be configured through BackupPC's web interface.

Open a browser and navigate to:

backuppc_server_ip_address/backuppc

You will be prompted for a username and password. The username is "backuppc" and the password is what you set with the htpasswd command earlier.

Set Up Client Configuration
On the left-hand side, click on the "Edit Hosts" link.

  

Click "Save" at the top of the page.

Configure Transfer Settings
Click on the "Xfer" tab on the top of the page. Under "XferMethod", select "rsync". Under "RsyncShareName", select the path you would like to back up.

You can leave it at "/" to back up the entire computer. You can also click "Add" to add additional areas to back up if you choose not to target the entire computer.

If you are backing up the entire computer, you'll need to add an "excludes" rule.
In the "BackupFilesExclude" segment, type "*" to match all shares. Then insert the values "/proc" and "/sys" to exclude these directories from back up.

 

Configure Backup Schedule

The default backup schedule is:

    Full backup
        Every 7 days
        Keep only newest copy

    Incremental backup
        Every day
        Keep the six most recent backups

If you would like to change the interval, click on the "Schedule" tab on the top bar.

 Note: You will notice that full backups have a value of "6.97" in "FullPeriod", and likewise, incremental backups have a value of "0.97" in the "IncrPeriod" field. These are values corresponding to 7 and 1 day respectively, since it accounts for the time to complete the backup as well.

You can modify the number of backups that the system maintains. You can also specify times when no backup should be performed by setting up "blackouts" where no backup can begin.

In this guide, we will stick with the default values.

Remember to click "Save" if you make any changes.

Run a Manual Backup

To run your first full backup manually, select you client from the "Hosts" drop-down menu in the upper-left corner.

You will be taken to a client summary page. Click "Start Full Backup" under the "User Actions" section.

You will confirm the action on the next page.

 

Your backup should complete shortly, depending on the size of the droplets.
