Linux file system .

Hello everyone, my name is Harshvardhan and I would like to welcome you to my blog in the Linux file system, let's take a quick look at what we will be discussing on this blog: what is a file system, what file system contains and what are the basic commands that are executed.

so let's get started;)

What exactly is a file system really ?

A File system is used to control how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stops and the next begins.

A file system can break data into pieces and give each piece a name. In this way, the data is easily sorted and identified.

Each data group is called a "file", while the structure and concepts used to manage data groups and their names are called "file system."

To put it bluntly: A file system is a data management system.

What is data management?

A logical format for data management is the "file + directory + directory tree", which is the most common form of data format used by current file systems (In Windows, the directory is called a folder).

Data related to data management logical structure + data = logical component of file system. Different data management schemes with results that lead to different file systems.

What is a directory?

The index is a group of files. The guide is divided into two types:

• Root directory.
• Sub directory.

directories are used to organize your data files, programs well.

File system configuration:

The file system is made up of 3 key elements

1. API (application programming interface).
2. Data.
3. Physical storage for that data.

Let's do a simple fun activity (including simple instructions used for a directory in a file system):

Use the mkdir command (simply used to create a new directory).

         mkdir dir22

      

     2. The following list of recent documents with the help of the ls command:

        ls -ld dir22

     

      3. To change the active directory use the cd command:

        cd dir22

     4 To print the current active directory, use the pwd command:

        pwd

     5. Write all:

       ls -l

Thanks for taking the time to read a little about linux file system in my opinion hope you enjoyed it thank you !!

 

Serverless Backup System

Serverless backup is also a kind of network-based backup that seeks to limit the role of production servers in backup procedures. The main objective of serverless backup is provide disk-to-tape or disk-to-disk backup without depleting server resources.

Generally, in this duration a production server can devote to processing requests from applications is restricted by the number times it must reserve to repeat data. Removing backup procedures favors the production servers as it frees the servers so it can process more data.

Many serverless backup systems enable provisions like disk-to-tape or disk-to-disk backup, vendors who provide this kind of service may map the copy function slightly differently in comparision. as an example , backup could even be performed by an appliance, which can be an actual physical device or a software function during a bigger storage management product.

                        

A number of companies provide / offer serverless backup services, including Arcserve with its Arcserve Unified Data Protection (UDP), Dell EMC and its NetWorker software and Veritas Technologies' NetBackup appliances. The CA and Veritas products are supported a process mentioned as disk imaging. These applications use an intelligent agent to make a snapshot copy of tips that would the data . The snapshot copy consists of an image of the pointers, which indicate things of the data , but isn't yet a backup of the data itself. the actual backup still must happen, supported the snapshot. The intelligent agent and backup procedures communicate through the Network Data Management Protocol (NDMP).

Another method of performing a serverless backup is via XCOPY, the extended copy function within SCSI. during this case, the server initiates and manages the backup, but isn't involved in actually backing up the data . The SCSI XCOPY command simply tells the data to duplicate from one device or location to a special .
