Backup failed: Script does not exist urbackup/post_full_filebackup

Hello.
My initial full file backup fails with

12/01/20 19:21 DEBUG HT: Renaming file to “/backups/my-PC/201130-1938/C/temp/disklayout.txt”

I’m running the official docker image, lastest, pulled yesterday. It is running on a synology NAS.

Here it seems to fail after the /post_full_filebackup file is not present in the mounted docker volume.
Maybe the startup script of the docker image could create those files?

No, that’s normal. The “DEBUG” level (not “ERROR” or “WARNING”) message is just saying UrBackup did not run any post full backup script because it didn’t find one. DEBUG messages are for the developer’s or administrator’s information, just as INFO messages are for the user’s information but otherwise do not indicate a problem. It is useful if you think you have a proper script but accidentally misspelled part of the name.

There should be other ERROR messages in your log referring to the “disk problems” mentioned in the backup failure message.

Ah, I was mislead by the “above” then.
Thanks.
