@lzx  , It is not about the load on the confluence at the time but about the large content. I would never rely on xml backup for production.

For this xml backup issue, you could try the troubleshooting in https://confluence.atlassian.com/doc/troubleshooting-failed-xml-site-backups-149212.html

The error logs given in the question doesnt have much details to troubelshoot

There are not many users of confluence. I set up the xml backup at 2 o'clock in the morning. Since the backup, the memory usage rate has been very high until the 16:30 pm. I checked the log and found that the backup task at 4 o'clock in the morning is over. Is there any good solution? What information do you need?
