Description of my issue
After spotting some SD card error on my old instance, I’ve created a backup with the CLI, named backup-rpi-yuno.one.
I installed a frsh Yunohost server on a new SD card, but I struggled a little to make it not failing directly for a restore, because I couldn’t see it with the yunohost backup list command. Indeed, the backup had been created as a folder, and was not recognized by Yunohost until I tar.gz it (not even with tgz extension, quite weird). Well, this issue resolved, I have been able to go further, after makin a symlink towards the attached disk hosting the tar.gz file:
admin@yuno:~$ sudo yunohost backup list
archives: backup-rpi-yuno.one
admin@yuno:~$ sudo yunohost backup info backup-rpi-yuno.one
created_at: 2022-09-10 13:59:50
description: Full backup before migration to new SD card.
path: /mnt/seagate/backup-rpi-yuno.one.tar.gz

admin@yuno:~$ ll /home/yunohost.backup/archives/

-rw-r--r-- root/root 3023 2022-09-10 14:02 info.json
And here is the content of info.json inside the archive:

I’ve tried to restore the full archive, but it failed miserably (a problem related to a no matching hostname, or hostname not set, I don’t remember well).
So I reinstalled the SD card (because the apt update were failing after that), I’ve made a restore test with a simple app, such as ttrss, but also got an error: https://paste.yunohost.org/raw/bugefivixo
I’m surprised about some env variables which do not match my domain name (using maindomain.tld instead of yuno.one):
YNH_APP_BACKUP_DIR: /home/yunohost.backup/tmp/backup-rpi-maindomain.tld/apps/ttrss/backup

YNH_CWD: /home/yunohost.backup/tmp/backup-rpi-maindomain.tld/apps/ttrss/backup
Did I messed up with my manual tar.gz archive, or is there another problem?
Let me know if you need any other information,
Thanks for you help.
