I used Duplicator for over a year on a Godaddy server. After initial problems it worked like a charm. I used the backups to restore to a second domain that we use for testing.
We use Duplciator to backup our site every couple of days but did not restore it for testing for about 2 months since the previous restore was adequate for testing new features.
About 2 weeks ago we started to fail with 500 errors on the backup. We did get two backups that worked in the last 2 weeks. We tried to restore one of these backups into our test domain and it also failed with a 500 error. We tried it several times even reverting to backups we did 4 months ago. They all failed.
We want to restore the backup so that we can test an upgrade to the latest version of WP, Duplicator and several other plugins.
I read one of the posts here about filtering out some of the larger files or directories. We tried it and it worked. We decided to filter out the wp-content directory and the size of the package was substantially reduced (the zip file reduced from over 70mb to about 10mb). However the restore still fails with a 500 error.
We increased both the memory and timeout values in php5.ini with no success.
I called Godaddy and asked about a problem with timing but they claim it is not their problem.
