Hi Tim,
I’m sorry to hear that your backups aren’t unzipping correctly. Although this should be possible factor such as the size of the backup and max execution time might cause issue. In order to figure out what might have gone wrong, can you check your backup archive log for us?
Navigate to Total Upkeep > Tools > Logs and check the log file with a name like archive-XXXXXXX.log
with a timestamp corresponding to one of your failed backups.
If you’re able to reply here with the text in that log file, we’ll be able to take a closer look at what’s going on. I can say that typically there is no need to unzip your Total Upkeep backup as the full zip can be managed directly through the Total Upkeep dashboard of your WordPress website or the WordPress CLI? Is there a particular reason you need to extract the full backup to your local system? Are you having trouble restoring a backup to a local instance of WordPress perhaps?
We look forward to hearing from you and assisting you further with this Tim! Thank you.
