how to resume download in wget for google takeout data

Question

I have 13 GB gmail data based on a discussion here

https://superuser.com/questions/1502126/13-66-gb-out-of-15-gb-used-in-gmail-delete-emails-that-consumed-space

I decided to download all emails in mbox format using google takeout. I signed and got a link after 24 hours to download all data. I have a slow connection so when some interruption happened I decided to switch to my mobiles 4G connection inside the virtual machine in which I was downloading my data some how I got dns resolution failures. So I switched back to my broadband connection.

Now starts the problem I was downloading part 1 of 13 Gb of google take out data from a lik that was generated via google in following format

now when I try to resume download I open in firefox the link to download all data again and new link is generated.For the new generated link I again try to download

debian@osboxes:~/Downloads$ wget -c https://takeout.google.com/takeout/download?j=ffff-9ac7-4c4d-826f-a2f96dbc8e80&i=0&user=116364599410907918080&rapt=ffff

when I do an ls to see what is the file name of previous download I see some thing like this

debian@osboxes:~/Downloads$ ls
'20191210T045548Z%2F-1183649478904650607%2F675b18b0-9ac7-4c4d-826f-

I am not able to understand how do I resume download in this case. Here are a few relevant screenshots


since I have an internet connection which disrupts so I have to use wget and I am not able to understand what mistake I am doing the previously downloaded file becomes useless if for any reason download was interupted I have to authenticate myself online generate download link again but then don't know how to use previously downloaded 600 Mb or 700 Mb and in my case if I start everything a fresh connection breaks again so I am in a chicken and egg problem.

Upon issuing wget -c

debian@osboxes:~/Downloads$ wget -c https://takeout.google.com/takeout/download?j=675b18b0-9ac7-4c4d-826f-a2f96dbc8e80&i=0&user=116364599410907918080&rapt=AEjHL4MhtvhATVMv-AiHyg

Answer 1

Make sure to quote your arguments correctly. & has a special meaning in shell commands (run command in the background, hence you got [1] [2] [3] unintentional background tasks), so for URLs that contain the & character, it must be quoted or it will be misunderstood.

$ wget http://some?special&url&parameters   # wrong
$ wget 'http://some?special&url&parameters' # correct

As for the incorrect filename, wget resumes properly even if URL filename and local filenames do not match, example:

$ wget -O customname -c http://speed.hetzner.de/100MB.bin

customname           67%[+++++++++===>       ]  67.20M  1.74MB/s    eta 20s

So this file is called 100MB.bin on the webserver but saved and resumed under customname and it works.

However, resuming in general is a concept that has to be supported by the web server. If the webserver refuses to send partial content, it's possible you have no choice but to re-download everything from scratch.

Also I'm not entirely sure how Google download servers work. If it generates a new link every time, there's a chance it may not actually be the same file. Some places offer downloads as zipped archive that is generated on the fly so it's different every time it's generated, and trying to resume would result in a corrupted download instead.

If you have a rented vServer somewhere you could also download there first, then move it over to your unstable home connection.
