Hello, these files are empty, but makes me wonder what is wrong. At same time i have set Retention 5 in Daily backups section of the WHM/Backup configuration. So it is strange older backups are not deleted per above output. The "Strictly enforce retention, regardless of backup success." is not ticked.

Update: temporarily until this is solved, i setup a cronjob to delete all daily backups in /backup except 7-1=6 last/newest backups:
50 22 * * * root for dailybackupdir in $(ls -t -A1 /backup|grep -|tail -n +7);do /usr/bin/ionice -c2 -n7 find /backup/"$dailybackupdir" -delete;done

The docs suggest that the pruning of backups using the Strictly enforce retention, regardless of backup success switch will only happen after at least 1 (one) completed successful backup

Each Strictly enforce retention, regardless of backup success setting overrides the standard behavior for that backup type. If you select this option, the system will always retain only the desired number of backups with at least one complete backup.

@postcd, That cron seems a bit dangerous to me. If, for whatever reason, '$dailybackupdir' isn't set, you'll delete all your backups. You may consider setting nounset:
BashFAQ - Greg's Wiki

Really, the entire forloop could be replaced by one find command.

Regardless, I would recommend investigating why your backups are failing. You can use the oneliner below to check all backup logs for all errors that would lead to an incomplete backup(paste the entire command at once):
Code:
for log in /usr/local/cpanel/logs/cpbackup/*; do printf -- "------------------------------\n%s:\n" "$log"; while read err; do grep "$err" "$log"; done <<EOF;done

Backups was not created, i run above mentioned script to find errors in backup logs and this was found:

[2017-11-01 03:28:01 +0000] Bailing out.. you must set a valid destination for backups
... many same errors ...

In WHM / Backup / Backup Configuration, the "Default Backup Directory" is set to "/backup".

The directory exist, but is empty:
Code:
# ls -la /backup; stat /backup
total 8

drwxr-xr-x 32 root root 4096 Oct 31 10:40 ../

I ran the backup manually from command line: /usr/local/cpanel/bin/backup --force
and it seems to finished and files are there in /backup and no "backup_incomplete" file.

[2017-11-01 10:21:56 +0000] info [backup] Sent Backup::Success notification.

a few days passed and backups are now created automatically without issue. Do not know why it was nto working.
