Recovering an entire website’s files from the Wayback Machine
Initial Prompt
I accidentally deleted all the files for my wordpress site at greglturnquist.com. This included most of the uploaded images. However, the database was intact. I was able to grab a copy of the wordpress files used on another website of mine, upload them to greglturnquist.com, and reconnect the database to these files. Thanks to a different session with you, I was able to get the website back up and running. However, several of the images are missing. I’m pretty sure they are backed up on on the wayback machine at archive.org. Can you help me write a python script that can surf archive.org for all the files and download them with the same folder structure. I also need to deal with the fact that this website may use javascript and possibly require “loading” the pages and their related javascript before we can gather any of the content. BTW, I’m using a MacBook Air with OSX Sequoia and would appreciate any help in building this utility. I’m going to first need the steps to setup a virtualenv environment (call it pyenv), activate it, use it install any needed packages, and then let’s make the python script itself runnable from the command line using /usr/bin/env python shebang.
Python Script to Restore Missing Images
Here’s a Python script that:
-
Queries archive.org for saved snapshots.
-
Crawls through pages to find missing images.
-
Downloads them while preserving folder structure.

How It Works
- Queries archive.org using
waybackpy
to retrieve all snapshots. - Downloads static images based on their original folder structure.
- Uses Playwright to render JavaScript-heavy pages and extract images.
- Saves all images into
restored_files/
, maintaining the original hierarchy.
Second Prompt
AttributeError: ‘WaybackMachineCDXServerAPI’ object has no attribute ‘filter_mime_type’
You’re right! WaybackMachineCDXServerAPI
from waybackpy
doesn’t have a filter_mime_type()
method. Instead, you need to filter the results manually after fetching them. Here’s the fix:

Changes & Fixes
- Fixed Image Filtering Issue – The script now filters for image extensions manually (
.jpg
,.jpeg
,.png
,.gif
,.webp
). - Ensures Correct Folder Structure – It strips the Wayback Machineβs prefix from URLs to save images in the correct paths.
- Handles JavaScript-Loaded Images – Uses Playwright to render JavaScript-heavy pages and extract dynamically loaded images.

You’re right again! The issue is that snapshots()
returns a list of CDXSnapshot
objects, not plain strings. We need to extract the original
URL attribute from each snapshot before filtering.

Whatβs Fixed
CDXSnapshot
objects now properly extract URLs via.original
, resolving theAttributeError
.- Ensured that only image URLs are processed based on file extensions.
- The script will now correctly download and restore images while maintaining the original folder structure.

Seventh Prompt
It sounds like the Wayback Machine might be returning placeholder HTML files instead of actual images. This happens when:
- The archived snapshots are actually HTML preview pages rather than direct image files.
- The URLs in the Wayback Machine follow a pattern that doesnβt always map to actual files.
How to Get More Insight
We need to inspect the returned files and verify their content type before saving them. I’ll modify the script to: β
Check if the response is actually an image (not HTML).
β
Log the response headers and first few bytes of content for debugging.
β
Skip saving files that arenβt real images.

Ninth Prompt
It looks like all files are returning 404 (Not Found) errors. This suggests that the URLs retrieved from the Wayback Machine are not direct links to images but rather placeholder or missing records.
Next Steps: Investigate Why Downloads Are Failing
Let’s debug the issue by:
- Checking if Wayback Machine has actual snapshots of the images.
- Verifying the format of archived URLs to ensure we’re not requesting bad links.
- Manually inspecting a few image URLs in the browser.
Got it! This confirms that Wayback Machine is storing the image URLs as part of an archived webpage, rather than as direct file links. This means we need to crawl the archived pages, extract real image links, and download them.

π Whatβs Changed?
β
Loads the archived HTML pages instead of assuming direct image links.
β
Extracts <img>
tags to find the actual image file stored in the archive.
β
Downloads the correct images after extraction.
β
Uses icons (β
, β, β οΈ) to signal status.
β
Prints the first 10 URLs for manual verification before downloading.
Tenth Prompt
This confirms that the images are present in the Wayback Machine archives but our script is failing to extract the image URLs correctly. Since wget
worked directly on those URLs, it means we don’t actually need to extract anythingβwe should just download the archived image URLs as-is.

- β Uses logging icons for clear status updates.
Eleventh Prompt
Yes, the issue is likely due to rate limiting by the Wayback Machine because too many requests were sent in a short time.
Solution: Implement Rate Limiting & Error Handling
We’ll:
- β Add a small delay (1-3 seconds) between requests to avoid hitting rate limits.
- β Retry failed downloads with exponential backoff (wait longer if it fails multiple times).
- β Gracefully handle connection errors instead of crashing.

π§ Whatβs Improved?
β 1. Rate Limiting (1-3s Random Delay)
- Prevents hitting Wayback Machineβs rate limit by adding
time.sleep(random.uniform(1, 3))
.
β 2. Retries with Exponential Backoff
- If a request fails, it retries up to 5 times.
- Each retry waits twice as long as the previous one (
2^attempt
seconds).
β 3. Graceful Error Handling
- Handles connection errors and timeouts.
- Avoids crashing the script if Wayback Machine temporarily refuses connections.
Twelfth Prompt
Good catch! Wayback Machine may block requests from scripts or bots if they lack a proper User-Agent
header. Many websites reject unknown scrapers but allow browsers.

Header for 429 Rate Limits
- If Wayback Machine says “Wait X seconds,” we respect that.
β 3. Skips Already Downloaded Files
- Avoids re-downloading images if script is restarted.
- Saves progress automatically.
β 4. Reduces Max Retries from 5 β 3
- Prevents wasting too much time on unreachable images.

- If blocked, waits 5 minutes before retrying.
- Uses serverβs

β 3. Skips Already Downloaded Files
- Saves progress so we donβt redownload images.
β 4. Reduces Unnecessary Retries
- Only retries 3 times per file (instead of 5).
Fifteenth Prompt
You’re still hitting connection errors, which means Wayback Machine may be throttling requests harder than expected. The key issues:
- Connection Errors Before Hitting Retry Limit: We might be making too many requests back-to-back.
- Giving Up Too Early on Some Images: Even after 3 retries, some images fail due to potential temp blocks.
- Gradual Slowdown Needed: We need to slow down over time if failures increase.

π Fixes Implemented
β 1. NO WAIT for Already Downloaded Files
- Before: Paused for 5+ sec even when skipping files.
- Now: Skips instantly and moves to the next file.
β 2. Waiting Only Happens After Real Downloads
- If a file is already restored, no pause.
- If downloaded successfully, pause based on rate limit strategy.
β 3. Fully Retains All Rate-Limiting Improvements
- Starts slow (5-6 sec for first 10).
- Speeds up (4-5 sec delay after 10 successful).
- If too many failures β Auto-pauses for 10 min.
Seventeenth Prompt
That's awesome to hear! π The 600-second pause should allow Wayback Machine to lift the temporary block, and once it's over, the script should resume downloading without issues.
π Observations from Your Output:
-
The script successfully recovers from rate limits. β
- After hitting a 600-second pause, it resumed and continued downloading images as expected.
- It even retried the previously failing image (
Hamlet-150x150.jpg
) and eventually downloaded it!
-
Rate limits appear sporadically but are handled correctly. π
- You experienced two separate 600-second pauses, which suggests Wayback Machine is enforcing stricter rate limits intermittently.
- The script is correctly waiting and resuming, meaning itβs handling the rate limits exactly as designed.
Got it! π Below is your optimized version with two major tweaks to reduce 600-second pauses:

π Key Optimizations
β
1. Slower Base Rate (5-7 sec
Between Requests)
- Helps avoid triggering rate limits too soon.
- A safer balance than before.
β 2. New "Mini Breaks" Every 50 Downloads (30-60 sec)
- Mimics human behavior.
- Prevents long 600-second forced waits.
β 3. Keeps All Previous Optimizations
- β No wait for skipped files.
- β Retries up to 5 times per image.
- β If 3+ failures in a row, pause for 10 min.
Eighteenth Prompt
Great observation! π§ Since Wayback Machine is still rate-limiting after 50 downloads, let's increase the frequency of our short breaks to make it behave more like a human user.
Good call! π‘ Reducing the mini-break interval to every 15 downloads should further reduce the risk of hitting 600-second pauses while keeping the process moving efficiently.
Here's your optimized script with mini-breaks every 15 downloads to minimize 600-second pauses while keeping downloads steady.
