Daily backups failing after upgrade to 7.2.1

[Adrian Gilbert]

I've had a daily backup that has been working properly for several years and many upgrades.

After the latest upgrade from 6.15 to 7.2.1, they have started to fail with:

2020-02-04 13:42:52,980 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.

I've tried changing the log level to INFO for com.atlassian.activeobjects.confluence.backup for more detailed logging (And even TRACE), but it doesn't give me any information on what file it's attempting to create and fail on.

Dear @Adrian Gilbert

java.io.IOException: Permission denied

can you check if the service user running confluence has write access to $CONFLUENCE_HOME/backups ?

It has permissions to the directory /var/atlassian/application-data/confluence/backups

drwx------. 2 confluence confluence 6 Apr 14 2018 backups

And it also has permission to the folder that I've got configured for backups to be saved to, which is /mnt/Backups/confluence/

drwxrwxrwx. 1 confluence confluence 20580 Jan 16 02:00 confluence

It's interesting to note that the January 16th @ 02:00 modification time on the second directory is also the last time that the backups worked. 

And the confluence user can create files in the directories:

[root@03_confluence confluence]# sudo su confluence
[confluence@03_confluence confluence]$ id
uid=1001(confluence) gid=1001(confluence) groups=1001(confluence) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[confluence@03_confluence confluence]$ touch foo.txt
[confluence@03_confluence confluence]$
[confluence@03_confluence confluence]$ ls -al foo.txt
-rw-rw-r--. 1 confluence confluence 0 Feb 5 08:22 foo.txt

Does Confluence run with the user "confluence"? Have you tried to set

chmod 777 backups

Hello? Anyone? It's still failing.
