Hello Israodin,

Thank you for contacting us about this. I have a few questions for you.

1. What is your Confluence version?
2. How are you creating the backup? Let us know the exact process you are using.
3. What type of database are you using?
4. What are your current server resources?

The logs you supplied do not contain any error messages. You'll want to check your logs again and look for any error messages which start with the line ERROR.

You can check here if it's an issue with an XML backup for advice on how to resolve it:

• Troubleshooting Failed XML Site Backups

Note that we only recommend the XML site backup for testing or small sites. You can try to backup your site with the solution below as well:

• Production Backup Strategy

Let me know if you have any trouble or questions.

Regards,

Shannon
