Multi-Site + WPCron -> Multiple Backups
-
Thanks a lot for your great plugin!
As others reported already, there is an issue with multi site installations together with WPCron. I managed to work around it with an external Cronjob Service, but i would love to see this bug fixed and everything again under the control of our system.I made some tests and want to share my findings with you – maybee it helps fixing the problem:
– I have an multisite installation with 19 Sites (1 MasterSite 18 Subsites)
– lots of sites started as a Clone of another Site
– My Job is a Database Backup, ALL Tables, daily at 2:20, Tar GZip, Upload to Dropbox
– When i start manually or via external link: everything is fine: 1 Backup, all Tables, Duration approx. 30 SecondsLast night i switched back to WPCron, this is what i got:
– in the logs and in the Dropbox i find 8 Backup Files, written between 02:22 and 05:34
– inside these backups i find only the Tables belonging to ONE Site, so the data to 11 other sites and the master-installation Tables are not included!
– i can’t find a rule why it is these 8 sites out of the 19. There are new ones and old ones included, high and low Site-IDs, Sites with Subfolder-Adress and Sites with mapped Domains, high traffic and nearly no traffic sites.
– i installed the PlugIn WP Crontrol to have a look inside the Cron Tables: i only find in one old site (but not THE oldest) backwpup_cron: {“id:” 3} (this is my BackWPUp Job-ID)Any suggestions how to get WpCron running correct again?
Do you need any more logfiles or even special tests i should run for you? I would be happy to share more details in PM.
Thanks,
Claus

Noooooh, all errors still here.
Still multiple backups on multisite installation with wpcron … !may be this helps to find the error:
– yesterday I tried with a daily wp-cron at 11:05
– later I changed for 01:45
– at 1:45 there was ONE execution (see my happy post above)
– at 11:05 SEVEN backups were done (seven domains)!There should have been NO backup at 11:05. The job was ONLY scheduled for 01:45
Even if there was an execution re-scheduled at 11:05, there should be only ONE jobI think, there is an error in the re-scheduling part.
Where is the list of jobs stored by backwpup? cannot see ist in wp_options.Thanks for some help.
@christinck
You can find jobs list at wp_sitemeta table ??Btw,I’m testing multiple sites system with 5 sites, full backup every day and BWP stills running just fine, cannot reproduce this problem :/

I tested again and found out:
If you create a new Backup, it is ONLY in the wp-cron table of the main site in the multisite installation.
Aber first execution, it is (as a copy?) in all sites. So the second execution will be many times. (Nice to check with plugin “wp crontrol”)I will help myself by putting into function “run” in “class-cron.php” a
if (get_current_blog_id() != get_main_site_id()){
return;
}seems to help me quick&dirty.
