webdav unexpected response code 404

[mlewinskiParticipant]

I’m unable to backup to my subversion / webdav server. I can use tortoisesvn to upload the same .gz file manually via tortoisesvn. So I know that the svn server allows uploads and can write to the repo. This is what I have logged on the webserver:

On my webdav server here’s the logs from the web server failing:

And tortoisesvn succeeding with the same file:

I see this error also:

WebDAV: Chunk 1: A write error occurred
Error: WebDAV: Failed to upload to backup_2017-05-27-1655_My_Site_f97915129584-db.gz

I’ve tried define(‘UPDRAFTPLUS_WEBDAV_NEVER_CHUNK’, true);. That Chunk error goes away, and then Updraft claims the backup succeeds. However, I never have any files appearing in my webdav repository. This is especially concerning since by all appearances the backups worked.

The backup apparently succeeded and is now complete (May 27 17:10:33)

I control the webdav server, which is latest patched CentOS 7. The apache configuration isn’t anything too special, and I can modify if needed to make this work. These are versions:

httpd.x86_64                        2.4.6-45.el7.centos.4              @updates
mod_dav_svn.x86_64                  1.7.14-10.el7                      @base

Hi,

Please could you send us a copy of the full backup logs from the chunked and non-chunked backups?
These can be found in the Existing Backups tab.

The contents will be too long to post here directly, but you can use an online service such as Dropbox or Pastebin, and post the links here.

Best Wishes,
David N
