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
Dear BackWPUp Support
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 you
