Bug with PHP 7.0.0RC1

My webhost allows to try PHP 7, and with RC1 enabled the Backup Plugin runs into an error:

[27-Aug-2015 09:07:22] 1. Trying to create backup archive …
[27-Aug-2015 09:07:22] Compressing files as TarGz. Please be patient, this may take a moment.

[27-Aug-2015 09:07:31] ERROR: Step aborted: too many attempts!

Just wanted to give a heads up on this, since I am not using the PHP 7 in production tis is not really a big problem.

Best, Markus
