TL;DR: I am trying to (partly) ‘merge’ multiple Yunohosts into one. I intended to backup eg Nextcloud on one server, and restore it on the other that already has Nextcloud. It doesn’t work, because the application already exists. Can I change the backup-info.json, to have the application restore differntly?
This is the error on the target server:
root@online:~# yunohost backup restore 20211005-210844 Error: The following apps can't be restored because they are already installed: ffsync, nextcloud
I have a couple of similarly configured Yunohosts, but due to changes at the ISP, I can not run all of them at home easily anymore. One of them is to receive Nextcloud from all the others (it takes too much data for an affordable VPS).
In another thead, @charly suggests using a VPN for my description of the situation, but I realized I should be able to have multiple Nextclouds one the one remaining homeserver and keep things less complicated.
For the moment I am not looking at merging the Nextclouds into one instance.
My question now is: can I change the backup.info.json file to trick Yunohost into restoring the backup to eg nextcloud__2 (and __3, etc), so that they all keep working?
