Learning Restic - Pre-Requisites Skills & Environment Setup
Before touching the `restic backup` command, you need to master the basics of the Linux CLI, filesystem & permission concepts, and access to local/remote/object storage. In this episode you will also install the restic 0.19.1 binary, prepare the repository directory, and verify the entire environment is ready for the series.

Learning Restic - History, Background & Why You Need It
This episode tells the origin story of restic: a community project born in 2016 as an answer to the limitations of tar and rsync. You will also understand why restic is called "backups done right" — global deduplication, built-in AES-256 encryption, immutable snapshots, and support for many backends from S3 to a REST server.

Learning Restic - Core Concepts & Key Architecture
Repository, snapshot, and content-defined chunking are the three pillars of restic's architecture. This episode dissects the repository directory structure, the role of each component (binary, backend, key repository, and command), and the data flow from source files to encrypted blobs in storage.

Learning Restic - Repository Initialization
Repository initialization is your first door into restic: `restic init` for local and S3 backends, using `--repository-file` to store the repo URL in a file, and managing the repository password securely via env, gpg, or a secret manager so your data never stays locked forever.

Learning Restic - First Backup & Snapshot
This episode runs your first backup: `restic backup` with tags and exclude patterns so the backed-up data stays clean and organized. You will also learn to read the backup results through `restic snapshots`, `restic stats`, and `restic ls` to make sure the data is truly stored.

Learning Restic - Restore & File Extract
Restore is the real test of a backup. This episode teaches you how to restore an entire snapshot with `restic restore`, pull a single file to stdout with `restic dump`, and do partial restores using `--include`/`--exclude` without clobbering other directories.

Learning Restic - Deduplication, Storage & Compression
Restic's efficiency comes from content-defined chunking: repeated backups only store the delta, keeping storage lean. This episode dissects the deduplication mechanism, reads the real numbers with `restic stats --mode raw-data`, and explains the role of zstd compression (`--compression auto`) that has been the default since restic 0.14.

Learning Restic - Backends: Local, SFTP, S3 & REST Server
Restic writes to many storage targets through a single abstract backend layer. This episode compares the local, SFTP, S3-compatible (MinIO/AWS/GCS/Azure/B2), and REST server backends — complete with repository URLs, credential configuration, and upload/download limits for controlled bandwidth.

Learning Restic - Forget & Prune (Retention Policy)
Snapshots that pile up without limit will eat your storage. This episode teaches retention policy: `restic forget` with keep-daily, keep-weekly, keep-monthly policies, plus `--keep-within` and `--keep-tag`, then `restic prune` to remove unused blobs — all grounded in your RPO and RTO targets.

Learning Restic - Automating Backups with Cron/Systemd
Manual backups won't last long in production. This episode assembles a safe backup+forget+prune script with `set -euo pipefail`, a lock file, and logging, then schedules it with cron and a systemd timer, including verifying the backup result at the end of every run.
