<p>Hi everyone!</p>
<p>Apparently tomorrow 14:00 CET is the most suitable slot for this
session. The previous link for the BBB was <a
class="moz-txt-link-freetext"
href="https://visio.futuretic.fr/360">https://visio.futuretic.fr/360</a>
and the pad is there : <a class="moz-txt-link-freetext" href="https://eth.leverburns.blue/p/borg">https://eth.leverburns.blue/p/borg</a></p>
<p>I'm not sure the status of the backup is very clear: is it done
or not yet?<br>
</p>
<p>The goal of the session would be to end the upgrade to Debian
bookworm before we can install tinc right?</p>
<p>hugs for those who want some!<br>
</p>
<p></p>

<p>hi <br>
@ igni did you already start the backup solo <br>
thought we were agreeing on a date :: <a

<br>
and it seems wednesday 16/10 we can be more people present <br>
so can we do it all together that moment - as in the meantime
we received this message from ralph of [mur][at]<br>

it looks like the transfers broke off pretty early in the
process!<br>

I will write a script which will loop back and restart the
receiving server-side process!<br>
It will *keep* all files from previous attempts so that nothing
can go amiss :-)<br>
it will name the backup files like
"adele01.img.lz4.202410091415", ...<br>
and "jean01.img.lz4.202410091415", ...<br>
each new attempt will create a separate file! :-)<br>
<br>
use the lines as before again to commence transfer:<br>
(I added -N for netcat so it will terminate after the end of
file is reached. I noticed it just keeps going wailting for more
input otherwise)<br>
<br>
for adele, port 12346: dd if=/dev/<your-dev-on-adele> |
lz4 | pv | nc -N hamster.mur.at 12346<br>
for jean, port 12347: dd if=/dev/<your-dev-on-jean> | lz4
| pv | nc -N hamster.mur.at 12347<br>
<br>
<br>
let me know how it goes!<br>
<br>
so long,<br>
r<br>
<br>
If the connection breaks it will restart the listening servers
on the same tcp ports ready for transfar<br>

<blockquote type="cite"><br>
I'll prepare for 2 separate transfers now!<br>
install lz4 and pv on your servers.<br>
<br>
try some transfer locally to make sure the tools work.<br>
<br>
then you should run this line:<br>
<br>
dd if=/dev/<your-dev-on-adele> | lz4 | pv | nc
hamster.mur.at 12346<br>
dd if=/dev/<your-dev-on-jean> | lz4 | pv | nc
hamster.mur.at 12347<br>
<br>
and I start 2 corresponding server on hamster *now*, which
will store the streams to local files there:<br>
<br>
/backup/images/adelejean »nc -l -p 12346 | cat >
adele01.img.lz4<br>
/backup/images/adelejean »nc -l -p 12347 | cat >
jean01.img.lz4<br>
<br>
<br>
--> the server side is up and running *from now on* and you
can start your transfer whenever you're ready.<br>
<br>
*note:* the server processes will exit after your client
terminates. so if some error occurs on your side, I will need
to restart the server-side processes.<br>
<br>
it is the fastest way of transferring the data via the local
network (it is not encrypted - so only good for our local
network. it would be a rather poor choice for across the
public internet)<br>

<br>
how big are the disk(s)?<br>
we could do it with netcat!<br>
I'd open a netcat listening socket on hamster, our backup
server, and<br>
you could pipe the whole block device there via netcat...<br>

hello mur.<br>
we write you / the technical support -<br>
cc Andreas<br>
to see if you can follow up our request?<br>
<br>
on 12/09 we wrote ANdreas --<br>
<br>
-------------------<br>
<br>
Dear Andreas<br>
<br>
hope you are doing well.<br>
We want to upgrade adele server, but our backup server
has some issues<br>
so we are wondering if mur could make a full disk backup
for us?<br>
<br>
-------------------<br>
<br>
thanks for taking it in consideration<br>
