 * Dear BackWPup community
   We are having the same problem as the thread in the link
   below.
 * [https://wordpress.org/support/topic/decryption-key-needed/](https://wordpress.org/support/topic/decryption-key-needed/)
 * it is shown “enter your decryption key to decrypt your backup.”
   I have not set
   the encrypted.
 * I am using BackWPup version 5.2.3
   WordPress Version 6.8.1
 * Please tell me how to solve this problem.
   I am a beginner and I don’t know what
   to do. Please forgive me if my question is inappropriate.

 * Hello,
   Thank you for contacting us.
 * Please make sure you’re using the correct backup ZIP file when restoring. Here’s
   an example of the expected format: [https://prnt.sc/WXnRTb1criF-](https://prnt.sc/WXnRTb1criF-).
   Sometimes, the correct backup file is inside the ZIP you have, so it’s good to
   double-check.
 * If that’s not the case and you’re able to extract the backup files, you’ll likely
   need to manually restore the backup by following this guide:

 * Feel free to reach out if you need any help during the process.

 * Dear [BackWPUp Support](https://wordpress.org/support/users/saranshwpm/)
   Thanks
   your help.
 * I checked my backup file name. I think it is a correct file.
   the file name is,
   2025-06-09_02-38-33_Y4JDBRXZ01
 * The Zip archive cannot be opened in Finder on my Macbook either.
   How can I do
   about it ?Excuse me, bothering youregards

 * Hi,
 * Thank you for checking and sharing the file details.
 * If the ZIP archive does not extract on your system, it likely means the backup
   file is either incomplete or got corrupted during the backup or download process.
   This would also explain the decryption error.
 * Please check if you have any other backup file that extracts correctly and contains
   the full WordPress files.
 * Let me know if you need help with the restore steps once you have a working backup.

 * Thanks your help
 * Following your advice,
   I have tried to unzip other backup files.Since we back
   up once a week, I downloaded and tried 5 weeks of files.All failed to unzip.
 * Then I noticed something strange.
   I have downloaded the same backup file multiple
   times, from “Backups History” page. The size of those zip files is different 
   each time. And the overall file size seems to be smaller 10MB – 20MB.Is there
   something wrong with the compression of the downloads?
 * Sorry for all the things I don’t know for myself.
 * regards

 * Hi,
 * Thank you for checking and sharing this with us.
 * From what you described, it seems like the download may be getting interrupted
   or incomplete; which would explain the varying file sizes and unzip failure.
 * Could you please try downloading the backup again and check if the file size 
   looks correct before attempting to extract it? You’ll need a complete backup 
   file to restore successfully.
 * Let me know how it goes.
