Hi,
this night I upgraded to virtualmin from 4.15 to 4.16
I found that after updating the Scheduled Backup fails with the following error:
…
Copying Apache log files …
No such file or directory
Backup failed! See the progress output above for the reason why.
It is a bug?
Using Ubuntu Server 64bit 14.04
Thanks for the support.
Howdy,
There’s a bug report and temporary workaround for that issue here:
I solved as indicated in the post temporarily by disabling the option “Include log files”.
Thank You! 
I ask one last help… how can I remove the strings of failed backups which are no longer needed? As are so many I would clean up a little logs. There is a folder where log settle status strings backup?
I mean the logs where there is voice Showing logs from last 7 days …
Thank You.
I have solved for the cleaning of the log backup.
The log folder is located at: /etc/webmin/virtual-server/backuplogs/
Thank You!
