Scheduled Backup executed multiple times

  • Upgraded to 3.0.2 yesterday (it fixed two open problems, thanks!).

    But having a new one. Or actually this happened previously, but I didn’t explicitly mention as the two other issues were more significant:

    I scheduled a once-per-day backup, to happen at 6:50 in the morning.

    As this is a test-site, there is almost no traffic, i.e. the backup started at 7:03, finished after 53 seconds … then the next one started… altogether 5 times. From the activity log:

    As you can see, each “next” backup starts shortly after the previous backup is finished.

    I am slightly suspecting a “mis-interpretation” of options. I have configured to keep 5 backups always as minimum. It executed 5 times in a row. But I already had 4 previously created (manual) backups. In my humble opinion it does not make much sense to create 5 backups within minutes… But I’m not sure if this is the cause.

    Will check again tomorrow. Today I deleted 4 of the 5 automatic backups, keeping only one… curious what will happen tomorrow morning.

    Kind Regards, Herbert

    Hi Herbert,

    I think I’ve worked out the cause of this one and should be able to prevent it. I think WordPress may be triggering the schedule multiple times over a period of 3-4 minutes, and because the backup finishes within a minute it causes it to run again until WordPress flushes the schedule.

    I’ll update when I have something ready.

    Jason.
