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.

Second Prompt

AttributeError: ‘WaybackMachineCDXServerAPI’ object has no attribute ‘filter_mime_type’
You’re right! WaybackMachineCDXServerAPI from waybackpy doesn’t have afilter_mime_type()method. Instead, you need to filter the results manually after fetching them. Here’s the fix:

Changes & Fixes

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

AttributeError: 'CDXSnapshot' object has no attribute 'lower'

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.

What’s Fixed

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

The issue remains because CDXSnapshot objects don’t have a lower() method. Instead, we need to access the original attribute of each CDXSnapshot object properly.

  3. ✅ Asks for user confirmation (Press Enter) before downloading

Seventh Prompt

Okay I updated the script to use BASE_URL = “https://greglturnquist.com/wp-content/uploads/*”. That actually seems to list 1488 files it needs to download. However every file fails on download. I’m wondering if its because these are HTML and not actual image files. Anyway we can get more insight?

It sounds like the Wayback Machine might be returning placeholder HTML files instead of actual images. This happens when:

  1. The archived snapshots are actually HTML preview pages rather than direct image files.
  2. The URLs in the Wayback Machine follow a pattern that doesn’t 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: ✅ Check if the response is actually an image (not HTML).

  • ✅ Log the response headers and first few bytes of content for debugging.
  • ✅ Skip saving files that aren’t real images.

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:

  1. Checking if Wayback Machine has actual snapshots of the images.
  2. Verifying the format of archived URLs to ensure we’re not requesting bad links.
  3. Manually inspecting a few image URLs in the browser.
I manually tested the first image. Indeed it is a timeline not an actual image.

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.

Do we need some rate limiting?

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:

  • ✅ Add a small delay (1-3 seconds) between requests to avoid hitting rate limits.
  • ✅ Retry failed downloads with exponential backoff (wait longer if it fails multiple times).
  • ✅ Gracefully handle connection errors instead of crashing.

🔧 What’s Improved?

✅ 1. Rate Limiting (1-3s Random Delay)

Prevents hitting Wayback Machine’s rate limit by adding time.sleep(random.uniform(1, 3)).

✅ 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).

✅ 3. Graceful Error Handling

  • Handles connection errors and timeouts.
  • Avoids crashing the script if Wayback Machine temporarily refuses connections.

Are you sending a proper User-Agent header to mimic a browser?

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.

Looks like we got a lot further. But I think we still hit some sort of rate limit.

Yes, you definitely hit a rate limit again. But we’re close!

The good news is:

  • You successfully downloaded many images before hitting the limit. ✅
  • The User-Agent trick worked—you got past initial blocks. ✅
  • Retry logic helped, but we still need improvements for long downloads. ✅

🔧 What’s Fixed?

✅ 1. Longer & Smarter Rate Limiting

  • Now waits between 2-5 seconds per request (instead of 1-3).
  • This makes downloads slower but less likely to trigger blocks.

✅ 2. Uses Retry-After Header for 429 Rate Limits

  • If Wayback Machine says “Wait X seconds,” we respect that.

✅ 3. Skips Already Downloaded Files

  • Avoids re-downloading images if script is restarted.
  • Saves progress automatically.

✅ 4. Reduces Max Retries from 5 → 3

  • Prevents wasting too much time on unreachable images.

  • You can make up to 15 requests per minute.
  • If you exceed that, you get blocked for 5 minutes.

🚀 What’s Improved?

✅ 1. Enforces the 15 Requests/Minute Rule

  • Requests only once every 4-5 seconds (avg 12-15 per minute).
  • This keeps us under Wayback Machine’s limit.

✅ 2. Detects Rate Limits (429) & Auto-Waits

  • If blocked, waits 5 minutes before retrying.
  • Uses server’s Retry-After value if provided.

✅ 3. Skips Already Downloaded Files

  • Saves progress so we don’t redownload images.

✅ 4. Reduces Unnecessary Retries

  • Only retries 3 times per file (instead of 5).

Fifteenth Prompt

Much better.Still looks like we hit a rate limit: <rest ommitted for brevity>

You’re still hitting connection errors, which means Wayback Machine may be throttling requests harder than expected. The key issues:

  1. Connection Errors Before Hitting Retry Limit: We might be making too many requests back-to-back.
  2. Giving Up Too Early on Some Images: Even after 3 retries, some images fail due to potential temp blocks.
  3. Gradual Slowdown Needed: We need to slow down over time if failures increase.

🚀 What’s New?

✅ 1. Smarter Rate Control

  • First 10 images → 5-6 sec delay (slow start).
  • After that → 4-5 sec delay.
  • If failures increase → slow down automatically.

✅ 2. More Retries (5 Instead of 3)

  • Helps recover from occasional timeouts.

✅ 3. If 3+ Failures in a Row → Wait 10 Minutes

  • Prevents full IP blocks.

✅ 4. Still Skips Already Downloaded Files

  • No waiting when skipping files.

So far so good. I did notice that it has pauses in between files that already exist locally.

🔧 Fix: Remove Unnecessary Pauses for Skipped Files

You're absolutely right—the script should not wait between files that already exist locally. The problem is that even when a file is skipped, the script still enters the sleep timer, causing unnecessary delays.

🚀 Fixes Implemented

✅ 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.

✅ 2. Waiting Only Happens After Real Downloads

  • If a file is already restored, no pause.
  • If downloaded successfully, pause based on rate limit strategy.

✅ 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 → Auto-pauses for 10 min.

Seventeenth Prompt

It's working great! It hit a rate limit, but has paused for 600 seconds, so I'm waiting to see if it handles it smoothly and proceeds onward.

That's awesome to hear! 🚀 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.

Okay, here's an output showing two rate limits. You can probably see the times in between.

Too many failures in a row! Pausing for 600 seconds...

🚀 Observations from Your Output:

The script successfully recovers from rate limits. ✅

  • 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. 🔄

  • 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 it’s handling the rate limits exactly as designed.
Let's implement those tweaks to reduce the number of 600 second delays.

Got it! 🚀 Below is your optimized version with two major tweaks to reduce 600-second pauses:

🚀 Key Optimizations

✅ 1. Slower Base Rate (5-7 sec Between Requests)

  • Helps avoid triggering rate limits too soon.
  • A safer balance than before.

✅ 2. New "Mini Breaks" Every 50 Downloads (30-60 sec)

  • Mimics human behavior.
  • Prevents long 600-second forced waits.

✅ 3. Keeps All Previous Optimizations

  • ✅ No wait for skipped files.
  • ✅ Retries up to 5 times per image.
  • ✅ If 3+ failures in a row, pause for 10 min.

Eighteenth Prompt

Maybe we need to have that 30-60 second break sooner than every 50 downloads?

Great observation! 🧐 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.

Maybe make it every 15 downloads

Good call! 💡 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.
