Files can be transferred from one server to another using tools like SCP, SFTP, or rsync.
Use SCP (Secure Copy Protocol) to securely transfer files between servers. Example: scp file.txt user@server2:/path/to/directory
Use SFTP (SSH File Transfer Protocol) for interactive file transfers. Example: sftp user@server2
Use rsync for efficient synchronization of files between servers. Example: rsync -avz file.txt user@server2:/
You can schedule a job regularly using cron jobs in Linux.
Use the crontab command to edit the cron table
Specify the schedule using the appropriate syntax (minute, hour, day of month, month, day of week)
For example, to schedule a job to run every day at 3am, you would add the following line to the cron table: 0 3 * * * /path/to/command
Hard links and soft links are two types of links used in Unix-like operating systems to create shortcuts to files.
Hard links are direct pointers to the inode of a file, while soft links are indirect pointers to the file name.
Hard links cannot link directories or files on different filesystems, while soft links can.
If the original file is deleted, hard links will still point to the data, while soft links will be broken.
...
The /mnt directory is used as a mount point for temporary mounting of filesystems, and fstab is a configuration file that lists filesystems to be mounted at boot.
The /mnt directory is commonly used for temporarily mounting external storage devices or network shares.
The fstab file is located at /etc/fstab and contains information about filesystems to be mounted at boot time.
Entries in fstab include the device to mount, ...

NFS stands for Network File System, a distributed file system protocol that allows a user on a client computer to access files over a network.
NFS allows a user to access files on a remote server as if they were local files.
It is commonly used in Unix and Linux environments for sharing files and directories.
NFS uses RPC (Remote Procedure Call) to communicate between the client and server.
It provides centralized storage ...
