Backup failed - Logs unavailable. Maybe the logs were logrotated.

[GuillaumeRZ]

Hello,

Each time I try to launch a backup (manually or automatically), it failed :

For each failed, the error logs is like so :
Jul 11 16:59:11 Logs unavailable. Maybe the logs were logrotated.
Clicking on "Download full logs" give me :

{
  "status": "Failed Dependency",
  "message": "Log file removed/missing"
}

On my EC2 machine, I checked and I correctly have this folders :
/var/log/, /var/backups/, /home/yellowtent/platformdata/logs/ :

From what could it come from ?

Does the folder /home/yellowtent/platformdata/logs/tasks/ even exist? Maybe you purged all subfolders there?
If it doesn't exist, run:

mkdir -p /home/yellowtent/platformdata/logs/tasks/
chown yellowtent:yellowtent /home/yellowtent/platformdata/logs/tasks/

Logrotation would not kick in that fast, so maybe the system cannot write to disk/create new files? Do you see any errors in /home/yellowtent/platformdata/logs/box.log while triggering a new backup run? Does that file even have new log entries?

Doing cat /home/yellowtent/platformdata/logs/box.log gave me that :

It correctly resolved the issue. Thank you a lot !
