What are some of tools and utilities that facilitate backup in a Linux system? Research 2 software-based backup utilities for Linux. Describe and explain several important features.

How is backing up data files different from a cloud-based files synchronization?

You can backup selective files (for example, just data files) or image the whole system (OS, Apps and data files). What type of backup would you use for your personal computer? Why?

Explanation / Answer

Tools and utilities that facilitate backup in a Linux system are the following.

tar: tar stands for Tape achiever which is a common Linux backup tool.tar support variety of backup operations such as backup of servers and desktops and also with tar backup to multiple devices are also possible.

dd: dd is a Unix utility used in Linux system to make use of its power to backup entire hard disk and partitioning operations.dd is restricted to the root user since its careless use may erase the entire data.

cpio: cpio stands for copy input to output.it is flexible enough to backup an entire file system to a single file.

software-based backup utilities for Linux

fwbackups: its one of the easiest backup software for the Linux system.it makes the backup more user-friendly with the introduction of scheduled backups.and it allows the user to perform backup remotely with the tar.backing up and restoring is simplest in this tool.

Amanda: It allows the user to backup more than one system to a single backup server.it makes use of locally available backup utilities like 'tar, dd, dump' on the Linux system to perform the backup.another version of Amanda called Samba can be used to backup windows system to the same Amanda server.

How is backing up data files different from a cloud-based files synchronization

Backing up the datafiles is the process of creating an image based copy of the entire data items and whenever a failure and data loss has occurred, then that backup file can be used to restore the device to a state of a point before the failure has occurred (the backup created time).

Synchronization doesn't store a state of the device.it just update the cloud storage with the same copies of data files from the device and whenever the user needs to access the files remotely or in case of loss of the local copy, he can simply go to the cloud storage and access it.

You can backup selective files (for example, just data files) or image the whole system (OS, Apps and data files). What type of backup would you use for your personal computer? Why?

I'll go for the image of the whole system.

If you want to protect only the data items you can go for a simple data backup but if you want to exploit the power of backing up should go for whole system backup.

its the process of saving a state of the system at a particular point including your customized settings, the application that you have purchased and the valuable data also.backing up such a state will help you to recover from a failure that leads to lost all the files and settings from your system.
