I have used BackupWordpress on my hosted WP sites and it's the BEST by far, however I am having problems trying to get it to run on a site that is hosted on an IBM iSeries running Zend Server (should be like Apache on AIX).
When I click on the Settings/Backups link I get the following in the Apache error log (but no date/time etc):
sh: whoami: not found
sh: whoami: not found
sh: whoami: not found
sh: groups: not found
sh: groups: not found
sh: groups: not found
sh: whoami: not found
sh: groups: not found
If I update the backup Settings I get:
sh: whoami: not found
sh: whoami: not found
sh: whoami: not found
sh: groups: not found
I also get a file ".backup_warnings" created in the backups folder, it's content is:
{"php":{"7a8a67a97cf19a56925a5cf738eef4a7":"Undefined offset: 0, \/www\/zendsvr\/htdocs\/news\/wp-includes\/capabilities.php, 1106"}}
The scheduled backups are not firing (to my knowledge). I see no logs or errors.
If I manually run the backup I get a modal with the following:
Your backup completed but with the following errors / warnings, it's probably ok to ignore these.
Here's the response from the server:
sh: mysqldump: not found
sh: zip: not found
It does create a valid backup, but will not email it to me (it's only 300kb so not too large), and .backup_warnings is updated to show:
{"mysqldump":{"7aae56d420a6b753d1d92c508d49f2ee":"sh: mysqldump: not found\n"}}
I'm not sure if this is because of a fault in our setup or if we can't use BackupWordpress on an iSeries. Hopefully these errors make some kind of sense. I am willing to try and suggestions to help fix this.
