Daily backup fails

[Jérôme BARBIER]

Hello Community,

After having migrating database (h2->mysql) , reinstalling Confluence, restoring backup and upgrading to 6.4.0, every thing is green is healthcheck.

I have only one problem, my daily schedules backups fail.

2017-09-20 09:11:26,040 WARN [Caesium-1-2] [activeobjects.confluence.backup.LoggingBackupProgressMonitor] beginBackup Begin Active objects backup, change log level to INFO for com.atlassian.activeobjects.confluence.backup for more detailed logging.

 It seems to be related to a permission problem and the logs is asking to change  com.atlassian.activeobjects.confluence.backup to INFO, but i don't know in which configuration file i have to set this value.

Somebody could enlight me ?

Thank you

I managed to set the log via the GUI.

The log didn't help me that much.

I tried to set the scheduled backup WITHOUT attachement and it worked.

Then put back the attachement and failed.

I renamed /var/atlassian/application-data/confluence_2/attachments/ver003 and launched a backup (a lot of errors but the backup file was successfully created without the attachments)

Finally renamed the ver003 to original name and the scheduled backup now works...

Strange.
