Data backup runs at wrong time

NethServer Version: 7.4
Module: backup-data

I’m noting strange behavior on my Neth 7.4 VPS installation with respect to the backup-data settings. I have it set to run daily at 0100, but it appears to be running at 1900 instead:

The system is set to EST time zone (UTC-5:00), which doesn’t match the offset–the backup is running 6 hours early. The server is showing the correct time and time zone:

Not the end of the world, but doesn’t seem right. Where should I look to straighten this out?

Could you please paste the content of this file /etc/cron.d/backup-data ?

This is the relevant code:

github.com

NethServer/nethserver-backup-data/blob/master/root/etc/e-smith/templates/etc/cron.d/backup-data/10base

{
    $OUT = '';

    sub cron {

 	    # configure backup time and reminder times from the  db
        my $backupTime = shift;
        my $name = shift || '';
        my $backupMin;
        my $backupHour;
        my $backupCron = '';
        my $opt = '';

        if ($name eq '') {
            ($backupHour, $backupMin) = split (":", $backupTime, -1);
            $backupMin =~ s/00/0/;
            $backupCron .= "$backupMin $backupHour * * *"
        } else {
            $backupCron .= $backupTime
        }

The cron job is good, so probably there is a bug in the web interface.

Could you please check when the job is really executed inside /var/log/cron?
You also take a look at the content of /var/log/last-backup.log.

This server is a VPS at Contabo in Germany (UTC+1), and I’m not sure I’ve restarted the server since configuring Neth (and setting the time zone). I’ve done that now; I’ll see if it fixes things.

The restart fixed it–probably restarting cron would have accomplished the same thing.
