Website Backup with wget (Update 2024)

This repository contains a comprehensive guide and script to create a local backup of a website using wget with various options to optimize the download process.

Usage

Basic Command

To create a local backup of a website, use the following command:

wget -mkEpnp https://example.com

This will download the entire website and create a local copy with the same structure as the original website. The options used are:

  • -m: Enables mirroring mode, which means the entire website will be recursively downloaded.
  • -k: Converts all the links in the downloaded files to local links, so that the website can be browsed offline.
  • -E: Adds the .html extension to the downloaded files.
  • -p: Downloads all necessary files for each page, such as images and stylesheets.
  • -np: Does not follow links to parent directories.

Additional Useful Options

  • -c: Continues a previous download that was interrupted or stopped.
  • -r: Recursively downloads files from a website, following links and directory structure.
  • -nc: Skips downloading files that already exist in the local directory.
  • --timeout=SECONDS: Sets the read timeout for downloads. This can be useful if you want to stop the download after a certain period of inactivity and retry later.
  • --limit-rate=RATE: Limits the download speed to avoid saturating your network.
  • --tries=NUMBER: Sets the number of retries for downloading files.

Examples

Setting a Timeout and Retrying Later

wget -mkEpnp --timeout=30 -c https://example.com

This command sets a timeout of 30 seconds. If the download is interrupted due to the timeout, it can be resumed with the -c option.

Limiting the Download Speed

wget -mkEpnp --limit-rate=100k https://example.com

This command limits the download speed to 100 KB/s to prevent network congestion.

Increasing the Number of Retries

wget -mkEpnp --tries=20 -c https://example.com

This command increases the number of retries to 20, which is useful for unstable connections.

Creating a Log File

wget -mkEpnp -c -o download.log https://example.com

This command creates a log file named download.log to monitor the download progress and debug any issues.

Parallelized Downloads with aria2

If the website loads resources from multiple domains, consider using aria2 for parallel downloads:

aria2c -x 16 -k 1M https://example.com

This command uses aria2 to make up to 16 parallel connections with a segment size of 1 MB.

Additional Information

wget is a command-line utility for downloading files from the web. It supports a wide range of protocols, including HTTP, HTTPS, FTP, and SFTP. With its various options, it can be used for a variety of tasks, such as mirroring websites, downloading large files, and recursive downloads.
