Remote Backup Not Working If Owner not Admin

Remote Backup Not Working If Owner not Admin

already tested on server A (old) website : abc.com owned by user1
server B (fresh install) remote backup to A…
website abc info success but the web is not at public_html or everywhere

but website def.com owned by admin
successed 100%

then i try to re-do remote backup
still success but nothing
after that i just click one time [fetch account] without refresh the page
sucess (ithink this is because delay of write the db after change the website owner)
