@humptydumpty That's right. No way to get wildcard certs with wildcard DNS.
To get a wildcard certificate, one needs to be able to program/automate the DNS. Let's Encrypt (acme) protocol requires one to programmatically setup TXT entries as part of getting the certificate. With a wildcard DNS, we have to now way to automatically setup those entries.
The protocol for normal certificates has a "http" based flow which allows it to work with a single wildcard entry.
@michaelf Did you happen to change the backup format or other backup settings? Cloudron does delete backup of old "format" or if you changed the backup provider.
One thing you can do is: Backups -> Cleanup Backups. Then click on logs, it will tell us why each backup is removed (or not). Can you paste the logs here (or you can send them over to firstname.lastname@example.org if it seems sensitive).
@girish I just restarted my server after some security updates went through and SSHFS stopped working for me as well. I deleted the backup destination and added it again and it started working. I've been on 6.3.5 for a long while (perhaps since it's release) for reference...
@robi there is a already bunch of "workarounds" for rsync. Empty directories, executable bit of files cannot be stored in most object storage. So, there is fsmetadata.json file that stores this information outside of the files. When restoring, we use that file to restore back the state. I guess we can extend that file to also save and restore timestamps.
If anyone wants this leave a note and I can look into it in the future.
