Hi !
Sorry, i was very busy this week-end.
Still doesn’t work at night, i got this :
ssh: Could not resolve hostname p: No address associated with hostname
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(235) [sender=3.1.2]
But works with this :
sudo ssh fallback@backup.ndd.tld -i /opt/yunohost/fallback/send_process/ssh_key -v
Did you remove the domain name ? is it really what you got ?
If yes, check the syntax, you may have an error.
Sorry i didn’t have time to watch before today.
So i watched why i got this message and didn’t know why.
I deleted Fallback and installed it again and it works !
Thx for your help Maniack ! 
Have a good weekend !
Hi it’s me again ! 
When i add Seafile to the list of app, Fallback can’t backup it. Maybe because i have 500Go of datas, so it’s too heavy i don’t know.
I got this in the mail :

Fallback is using the yunohost backup moulinette, right ? Maybe i should ask to a yunohost dev ?
Thanks for your help
That’s an error on seafile side, as you can see, the error is
[Errno 6] No such device or address: '/opt/yunohost/seafile/ccnet/ccnet.sock'
And indeed, the backup can’t usually backup a socket, which is not a standard file.
You should open an issue on seafile repo to ask for a fix.
Ok i’ll see that.
Thanks for your help
Hi everyone and @Maniack_Crudelis,
Today I realised that the app is no longer maintained. I had to reinstall it and it no longer works at all… Are there any further plans?
Does anyone use a different way to maintain a fallback server?
Many thanks!
I still use that app for my personnal server, but I didn’t check it recently.
Could you tell me what was the error ?
Hi,
Thanks for your reply.
I’m having this:
usage: yunohost {backup} ...
[-h] [--output-as {json,plain,none}] [--debug] [--quiet]
[--timeout ==SUPPRESS==] [-v]
yunohost: error: unrecognized arguments: --no-compress
I’ve deleted the --no-compress in send_backup.sh but that hasn’t helped either.
Any ideas would be much appreciated.
That the same issue as for Archivist…
I’ll fix it, I need it as well
Thank you. Looking forward to your update. As I’ve said before, I don’t know how others do it.
Fix available on this branch Fix YunoHost 4.1 by maniackcrudelis · Pull Request #23 · YunoHost-Apps/fallback_ynh · GitHub
To be tested though…
I apologise for the late reply.
How can I test it please?
With the command line:
yunohost app upgrade fallback -u https://github.com/YunoHost-Apps/fallback_ynh/tree/fix_41 --force
Excellent, thank you!
Will get back here as soon as I’m done.
So far so good.

Not sure why I get the initial warnings (I always get them so not an issue here).
I’ve now launched an backup with send_process.sh > waiting for result.
OK here are some results @Maniack_Crudelis and @tituspijean

Hope this helps. Please let me know if I can do anything else.
Your first error seems to be related to the backup of Agendav itself, either the backup script of the app or an error with YunoHost.
You should try to backup the app manually from the admin panel or CLI to see if that script works.
The second one for the core is a common error, aparently never fixed…
If YunoHost fails a backup for whatever reason, you’re screw for any other backup you want to do afterward…
Clean the content of /home/yunohost.backup/tmp/ to fix that second error.
OK, script works.
Checked /home/yunohost.backup/tmp = empty
Launching > ./send_backup.sh again.
I was quite sure I did remove that already…
But it was in Archivist, not in this one !
