Hi everyone

As of December 2016, Atlassian removed WebDAV support for both Jira and Confluence Cloud applications. As such, I'm closing out this bug, as no longer relevant to our current cloud capabilities. 

Please see here for further details.

I tried with Wget curl and Downloadthemall fire fox extension.
The file is downloaded but when I unzip it is corrupted and does not extract.

Thanks for the tip, Pete – that works for me too. Here's an example close to what I used:

$ wget -t 0 --user="MYUSER" --password="MYPASS" https://example.atlassian.net/webdav/backupmanager/Application-backup-20130509.zip

It will automatically retry (and resume) the download if it gets interrupted. It looks like this is the simplest option we've seen so far, assuming your system has wget on it.

wget -t 100 https://user:pass@example.jira.com/webdav/svn.dump.gz worked for me..

and there's a -c option to continue if you already have some as well..

I tried Michael's second solution, but it also stopped after 1GB

curl -k -u "xxxxx:xxxxx" https://xxxxx.jira.com/webdav/backupmanager/JIRA-backup-20130201.zip -O --retry 999 --retry-max-time 0 -C -

% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
25 4093M 25 1050M 0 0 2102k 0 0:33:14 0:08:31 0:24:43 0
curl: (18) transfer closed with 3191557274 bytes remaining to read

The bash script worked fine.

Others have had success with cURL's retry option, e.g.:

curl -k -u "user:password" https://example.atlassian.net/webdav/backupmanager/JIRA-backup-20130131.zip -O --retry 999 --retry-max-time 0 -C -

The suggested DL manager worked fine for me, though my file was only 500M. It timed our with a normal browser DL 2x worked 1x.

One workaround is to use 'curl' on the command-line to download the file in a 'resume loop'. Here is a script that does this, and will stop once it detects the file has finished downloading. Note that you will need to edit the script to put in the correct host, username and password.

#!/bin/bash -u

if [[ $# < 1 ]]; then
	echo "Usage: ${0} FILENAME";
	echo "Where FILENAME is the name of the file produced by OnDemand's backup manager (e.g. 'JIRA-backup-20121005.zip')."
	exit 1;
fi

BACKUP_FILE="${1}"
MY_HOST="test.atlassian.net"
USERNAME="myusername"
PASSWORD="mypassword"
URL="https://${MY_HOST}/webdav/backupmanager/${BACKUP_FILE}"

# Detect total file size
FILE_SIZE=$(curl -s --head -u "${USERNAME}:${PASSWORD}" "${URL}" | grep -i '^Content-Length:' | awk '{ print $2 }' | tr -d [[:space:]])

while [[ ! -f "${BACKUP_FILE}" || $(ls -al "${BACKUP_FILE}" | awk '{ print $5 }') -lt ${FILE_SIZE} ]]; do
	curl -k -u "${USERNAME}:${PASSWORD}" -C - -o "${BACKUP_FILE}" "${URL}";
	sleep 5;
done;
