Backup issue

Hi,

I'm using the Perch backup app on a Perch 2 website, but when clicking 'Create Backup' it appears to load but I never get a file download, so if it is backing up I have no idea where it goes.

If it helps I'm using Safari on a Mac and here's my Perch diagnostic summery:

SUMMARY INFORMATION

Perch: 2.8.24, PHP: 5.3.3, MySQL: 5.1.73, with PDO Server OS: Linux, apache2handler Installed apps: content (2.8.24), assets (2.8.24), categories (2.8.24), perch_gallery (2.6), perch_sales (2.6), perch_news (3.6), perch_backup (1.2) App runtimes: <?php include(PERCH_PATH.'/core/apps/content/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_gallery/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_sales/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_news/runtime.php'); ?> PERCH_LOGINPATH: /admin PERCH_PATH: /home/.sites/93/site73/web/admin PERCH_CORE: /home/.sites/93/site73/web/admin/core PERCH_RESFILEPATH: /home/.sites/93/site73/web/admin/resources Image manipulation: GD PHP limits: Max upload 2M, Max POST 8M, Memory: 16M, Total max file upload: 2M F1: dc1fef2ad0fcd9f943c02ebb43d85dbc Resource folder writeable: Yes HTTP_HOST: www.xkengineering.com DOCUMENT_ROOT: /home/.sites/93/site73/web REQUEST_URI: /admin/core/settings/diagnostics/ SCRIPT_NAME: /admin/core/settings/diagnostics/index.php

In addition, when clicking 'crete backup' on 'entire CMS folder' I get the following error:

'Unable to open temporary file 'pclzip-56b1e8ea9eafe.gz' in binary write mode [code -1]'

Many thanks for you help,

Alex
