Cloudron backups with Hetzner storage box

[Benoit]

Hello, I want to set up my backups with Hetzner storage box and I would like your opinion on the best protocol to use for large volumes of data and to know if you recommend this solution, and if you are satisfied with it. For example, I have about ten apps, including a Nextcloud instance with 500 GB of data. My Cloudron backups are secondary backups, as I also take snapshots of my VMs using Proxmox Backup. Ideally, I would like to use rsync to make the best use of my storage space.

Thank you for your feedback.

If you go for Hetzner storage box for backups, then the SSHFS is by far the preferred choice as it can do snapshot rotation on the server side, since Hetzner offers a limited remote shell which we specifically use here.

I use that personally for a long time and I tend to say I would always recommend it over other storages for backups.

@nebulon how about the transfer speed? Do you also notice higher CPU or RAM usage? For a large volume of data in Nextcloud, do you think it's better than Object Storage? Thanks!

EDIT : i found this post https://forum.cloudron.io/topic/12340/cloudron-8-released/7?_=1727429391377 and it seems to be faster after the first backup with rsync, great news !

for backups it is great, for actual data volumes for apps, I would always lean towards server-bound storage. Hetzner does have great options also in their auctions with lots of disk space.

Indeed after using this for over a month it’s still a miracle to see backups finishing so quickly.

I once needed a restore of a WP app and that took about 3 minutes for about 2GB.

Problem with rsync / ext4 is the max 255 bytes name limitation that can conflict in Nextcloud with a deep folder depth also encryption not to mention which increases the char count of each file and folder.
The same goes for mails or anything where you can build deep structures with long strings.

If this is really an issue that we can hit with backups, there should be a big fat caveat at https://docs.cloudron.io/backups/

@necrevistonnezr I think @BrutalBirdie is referring to file name length limitations with encryption . It's listed at https://docs.cloudron.io/backups/#encryption . You can simply disable Filename encryption ...

file name length limitations

Yes but that also happens with no encryption at all if you have deep structures in Nextcloud / Mail

I'm just migrating from Contabo Storage to Hetzner because of issues with Contabo... and I hope I won't face your issues folks ! I'll keep you posted

[SansGuidon]

FYI the migration to Hetzner Storage Box coming from Contabo Object Storage was worth it and fixed all failures related to backups whether it was in term of stability or duration.
I didn't encounter issues yet, despite I'm using encrypted backups and i've plenty of apps including Nextcloud but I don't have as much data on it.
