Hi – I keep getting the following error 'An unknown response returned from Snapshot backup…&#

Hi – I keep getting an abort error when trying to run a backup (at the moment trying to send it to DropBox)

Full error is: “An unknown response returned from Snapshot backup attempt. Aborting. Double check Snapshot settings.”

I’ve check memory limits etc, per the other examples but it doesn’t seem to help. It looks like it keeps getting stuck on some of my woocommerce Database lines. This is the server info:

PHP runtime information

Display Errors 1

Error Reporting 71 – E_ERROR, E_WARNING

Max Execution Time (seconds) 30 The value displayed can be adjusted by Snapshot PHP scripts.

Memory Limit 256M – WP_MEMORY_LIMIT defined by WordPress wp-config.php.

256M – WP_MAX_MEMORY_LIMIT defined automatically by WordPress

Open Basedir Off

Safe Mode Off

ZLib Compression Off

Grateful for any help!

    Hello @Kieren

    Welcome to WPMU community!

    I hope you are well today and thanks for asking the question.

    Would you please try the following?

    Also, on the Snapshot > Settings page at the bottom there is an option to select the zip library used. Options are PclZip which is a library provided by WordPress. The other option is ZipArchive which is the native PHP version. Curious if you have better luck with switching. Normally from what I’ve seen the PclZip manages memory a little better. While the ZipArchive uses disk based cache for files.

    Please let me know.

    Cheers

    Thanks for the quick response Ash. Sadly, no luck with that either. The error seems to be a little bit random too – sometimes on different lines, but all generally to the end of the snapshot run list, and more often than not on the woocommerce database lines (which show rows 0/0).
