Snapshot Not Finishing Backup


I am having some trouble with Snapshot and unable to complete a backup. The problem appears to be within Themes and/or Plugins, as individual backups of just those fail when the backup get to the files. I have tried a managed backup as well, but also receive a 404 error. Please advise.

    Hello, and thanks for the reply. I added the provided to wp_config and I was able to Snapshots of Themes and Plugins by themselves. However, a Complete Snapshot failed with 'Error 404' and stopped on Files: : media/2016/11 @ 77% (files 10/13). The related log entry within debug.log is:

    PHP Notice: Indirect modification of overloaded element of WP_Hook has no effect in /home/user/public_html/ on line 58

    I did not see any other error logs or similar that would help with this issue. I also attempted a Managed Backup and it failed with a 404 about 1 minute in. While a backup was running, I tried to load the Dashboard in another tab with and Error 500. Any other ideas?

    Hello, I hope you are doing well. Snapshot is still having trouble and below is from the end of the Managed Backups Log:

    Individual Snapshots for Themes, Plugins, and the DB have completed successfully. A snapshot of only Media fails and a managed backup has yet to complete. I am not sure what the issue is, but was able to complete all Snapshots on the main www site yesterday. I have granted access to the www site as well, and FTP credentials provided can also access the www directory in case you want to take a look. Please advise and let me know if you have any questions.

    Thank you,

    Hi Mtwo,

    There is probably a very large file somewhere, or a file that Snapshot doesn't seem to want to copy.

    I may need to have a look at the files in your media folders.

    Can you send your details using the following contact form:

    Alternatively you can email direct to

    Mark for attn: Vaughan
    Include a ref URL to this thread.

    Please include the following details;
    - Site login details (super-admin if on multisite)
    - FTP login details so I can take a look at the media/heme/plugin files.

    Hello, I hope this messages finds you well. I did submit the requested information...Also, I am now having problems with backups on the main site. When I edit a snapshot I see the following error related to the WordPress Cron scheduler (WP_CRON).

    Your site has disabled the WordPress Cron scheduler (WP_CRON). When scheduling an archive to be created it may not run. Check your wp-config.php for the DISABLE_WP_CRON define. If found either remove it or set the value to "false".

    I have searched and tried the most frequent recommended fixed without success. Including define( 'DISABLE_WP_CRON', 'false' ); in wp_config, and I tried WP-Cron Control and added the cron job via cPanel. The scheduled snapshots are not working and only the DB snap works manually.

    I added a new Snapshot, "Complete Snapshot 2", and it failed on Files: : media 8% (files 1/13) with 404 error. What can I do to fix? Please advise.
