Course 4 - Learning Linux Shell Scripting | Episode 6: The Backup Plan
In this lesson, you’ll learn about: The Backup Plan — Data Management, Archiving, and Backup Automation
This section provides a deep dive into data management strategies, focusing on archiving, compression, specialized file systems, and automated backup solutions. It builds upon the previous lesson, where web interaction through shell scripting was introduced. 🗃️ Archiving Fundamentals • tar (Tape Archive):
This section equips you with a complete toolkit for data protection — from simple file compression (gzip, zip) and archiving (tar), to powerful synchronization (rsync), version-based tracking (git), and full disk imaging (FS Archiver). Together, these tools form the foundation for a reliable, automated backup plan that ensures data integrity and recovery across systems.

This section provides a deep dive into data management strategies, focusing on archiving, compression, specialized file systems, and automated backup solutions. It builds upon the previous lesson, where web interaction through shell scripting was introduced. 🗃️ Archiving Fundamentals • tar (Tape Archive):
- Create and manage archive files (“tarballs”).
- Perform operations like create, list, extract, append (-R), update (-u), and concatenate (-A).
- Use verbose output (-v), wildcards for file selection, and exclude unwanted directories (e.g., .git).
- Understand this archive format, similar to tar, used mainly in RPM packages and Linux kernel init RAM FS.
- Though less common, it remains an important legacy tool for low-level archiving.
- Compress single files efficiently.
- Control output to standard output (-c) and set compression levels (1–9, or --fast / --best).
- Use zcat to read compressed files without extraction.
- Achieve higher compression ratios than gzip, though with slower processing.
- Offers even stronger compression performance, ideal for minimizing storage space.
- Combines archiving and compression in one step, widely supported across platforms.
- A parallelized version of bzip2 using multiple CPU cores (Pthreads).
- Greatly speeds up compression but requires tar for handling multiple files.
- Create read-only, compressed file systems commonly used in Linux Live CDs/USBs.
- Access compressed data on-demand through loopback mounting, avoiding full extraction.
- Synchronize and back up files efficiently by transferring only changes.
- Support for SSH, compression (-z), and cron scheduling for automation.
- Perfect for maintaining remote or incremental backups.
- Apply Git’s versioning to regular files for incremental and differential backups.
- Track changes, mark snapshots, and restore previous versions.
- Not ideal for large binary-only datasets.
- Create compressed disk images of entire file systems, including metadata.
- Supports modern file systems like ext4, simplifying full restoration and migration.
