Hi Wolfgang,
Thank you for reaching out and thanks for using Total Upkeep backups and migrations plugin for WordPress.
I’m sorry to hear about the backups failing, we’ll be happy to help out. Total Upkeep makes a log every time you create a backup, and that’s going to be the place we want to check first.
Navigate to Total Upkeep > Tools > Logs and look for your most recent log with a name like archive-XXXXXXXX.log
. If you can copy that and paste it here, we’ll be able to get some more information about what went wrong.
We look forward to hearing from you.
