@nebulon I find the solution taking infos from this forum .

In fact, I opened port 53 TCP and UDP and Cloudron can resolve domain names.

Configuration now is:

All seems to working fine... I marked this thread as "Solved" 🙂

@nebulon Maybe https://askubuntu.com/questions/1210867/remount-cifs-on-network-reconnect ? (just expands on your link)

This could come in handy for the selfhost.cloud stuff @thetomester13 and I are working on 🙂

@mehdi Not sure I know enough yet about handling updates, patches & security so just running in good faith on all that at the mo.

Happy? Yes.

Confident? Sure - until something goes wrong 🙂

Just always thinking about prevention being better than cure.

Ok I gotcha myself because anyway I create my own pain 😉

so from what I understand
to being able to restore Cloudron verify the DNS first than app/data

I forgot to authorize my new IP in my Cloudflare API

code 9109 is probably related to the fact it was unable to edit the DNS.

correct in your case this should not be any issue as this is mounted like a regular ext4 which supports hardlinks just fine.

To know the backup scope, you can sum up all the apps listed there + email data + box data. Then you would have to multiple that by the number of backups which are stored (eg. once every day for 1 week or so) This would be the maximum of storage required using the tarball method. For rsync, it would be much less since it would do incremental backups.
