I am getting this error while cloning the site on aegir
Unknown option: --profile. See
drush help provision-backupfor available >options. To suppress this error, add the option --strict=0. [2.39 sec, 21.19 MB]
I am using aegir3 on ubuntu 14.04.4. Can anyone please help me solve this. I have searched on web but there is no solution regarding this issue. This issue also occurs while migrating.
