Hi Terry,
Yes, there is nothing unusual in /var/log/cron:
Apr 6 22:01:01 beam CROND[651585]: (root) CMD (run-parts /etc/cron.hourly)
[...]
/var/log/messages
Feb 24 23:00:03 beam dhcpd[1743]: DHCPREQUEST for 192.168.201.214 from 00:25:b3:e6:a9:18 via enp4s0
[...]
In the backup log:
Bbackup / /usr/beam /home /src /srcOld /dist /opt /scratch /data/svn /data/www /data/vwt /data/www /data1/kvm /data/database /data/vwt /data/backup at Mon 6 Apr 23:01:01 BST 2020
[...]
Maybe irrelevant, but just mentioning: the log extract from /var/log/messages is dated Feb 24, whereas the other two are dated Apr 6.
Best regards,
Iosif
