Hmmmm .....
in admin/cli/ php cfg.php > allsettings.txt
Then fgrep enable allsettings.txt do see a:
enableasyncbackup 0
in the 678 settings of a 4.5.7 moodle
Quick way to disable add a line to config.php
$CFG->enableasyncbackup='0';
The only 'restore' found:
restorernewroleid 3
Maybe there should be one for on/off of restore?
Didn't ask before, but will now ... the backups you are trying to restore, did they come from a moodle that was same version?
And, does the site you are trying to restore to have all the same addons that might be contained in the backups?
