Managed backups failing at 99% - Gateway Timeout

Managed backups are failing on my site, last one was at 99% and ended up returning a Gateway Timeout error.

The issue is only related to Managed Backups, I was able to create a complete snapshot.

Hello David

Would you please add the following defines to your wp-config.php file and then try running Managed Backups again to see if this resolves your issue?
```
define('SNAPSHOT_TABLESET_CHUNK_SIZE', 100);
define('SNAPSHOT_FILESET_CHUNK_SIZE', 100);
define('SNAPSHOT_FILESET_LARGE_FILE_SIZE', 104857600);
define('SNAPSHOT_FILESET_USE_PRECACHE', true);
define('SNAPSHOT_ATTEMPT_SYSTEM_BACKUP', true);
define('SNAPSHOT_IGNORE_SYMLINKS', true);
define('SNAPSHOT_MB_BREADTH_FIRST', true);
define('SNAPSHOT_SYSTEM_DEBUG_OUTPUT', true);
```
Defines should be added in wp-config.php right above the /* That's all, stop editing! Happy blogging. */ line.

Best regards,

James Morris

Hello David

Thank you for sending in that information. I'm afraid I've exhausted my resources on this issue and have flagged this ticket for our Devs to take a look at. There's ample resources on this site to support even massive backups. And I'm not finding anything that *should* stop Managed Backups. So there's something deeper at play I need the Devs to look into.

Please keep in mind that more complex issues such as this may take a little bit more time to debug. Thank you for your patience while our team sorts through this.

Best regards,

James Morris

Hi David ,

I've just re-checked the managed backups and I had no issues on your website.

I actually removed all the custom defines from within the wp-config leaving only the debug logging of Snapshot enabled to see if everything's going ok.

If you check your backups you'll see the full_backup-1532866919-full-b454dece.zip that was created during my tests.

Since you say it's your server, might there be any server side logs or any security addon to your server that temporarily ruled out the upload / api handling process with our servers?

I can't be sure since this worked at the moment without any extra effort of or code edits so it seems that it might have been an one-off thing.

Tell me if you experience the same issue again please so we can take a look further.

Regards,
Konstantinos

Curious indeed...

As you say the site is now backing up and auto-installing plugins, weird because this sit on the same server as a lot of my sites but was the only one experiencing issues of this sort.

Thank you for checking it and being thorough.

No problem at all! Tell us if you experience the same issue again just in case there's something else going on that I might have missed as well since everything worked as supposed to.
