Backup failure

Dmitriy Deev

Hello! Please help me! When I try to backup Confluence from the administration console, nothing happens but error:

The following error(s) occurred:

Hello there!

Thanks for coming up to Community and sharing your situation with us. Looking at the logs you sent us, I can not pinpoint exactly what is happening.

We have a similar situation related to MySQL. You can take a look here:

Can't create XML backup due to backupEntities Couldn't backup database data

Could you clarify a few points for us?

1. Are you using MySQL database with your instance?
2. Were you able to finish this backup at some point in the past?
3. Does this happen with scheduled backups?
4. Do you need to migrate your instance?
5. How much memory is currently allocated for your instance?

Looking forward to your reply Dmitriy!
