We understand that sometimes, there may be other apps being used in your store that warn against performing any importing or exporting while they are active.
Rest assured, Rewind does not use importing or exporting during standard functions. Backups are perfectly safe to run in conjunction with these other apps, as they are only reading data (which will not affect them).
It is worth noting, however, that a rewind/restore could be modifying data. So to best ensure that Rewind doesn't cause any issues with any other apps, we highly recommend not performing a rewind/restoring other versions of your store while these other apps are reading data.
