Syncthing
Syncthing is generally not a backup tool. But as we use snapshots on the ZFS pool, which can't be destroyed from syncthing, it's not a plain syncing tool which in the worst case would sync ransomware encrypted files in real time and cause data loss on all devices.
The Syncthing GUI will be available through the provided link after deployment.
To prefill the Syncthing dataset on your ZFS pool before sending it, install as described in Install Syncthing. You don't need to do this if you don't want to prefill the pool on your site.
Proxmox Backup Server 4
The use of a separate Proxmox Backup Server for uploading backups from another Proxmox Backup Server on HDD-Housing may offer greater security against ransomware and attackers. The Proxmox Backup Server connected to HDD-Housing should be operated in pull mode. If operating in push mode is necessary, you can find the necessary permissions here: https://pbs.proxmox.com/docs/managing-remotes.html#sync-direction-push
If you want to backup multiple Proxmox Backup Server, use namespaces or create seperate buckets and a Datastore for each bucket.
Documentation Proxmox Backup Server: https://pbs.proxmox.com/docs/index.html
Create a bucket in Minio
By clicking Create Bucket in Webgui on the top left and name it pbs:
Configure HDD-Housing S3 Storage in Proxmox Backup Server 4
Note: How to get the fingerprint from self signed certificate is shown in Install Minio S3 Storage Server on Debian/Ubuntu
Create Datastore
mkdir /tmp/hddhousing_localcacheClick Add Datastore and configure to your needs, example:
Create namespaces
Use namespaces for Pull Sync Jobs
Remotes must be configured first, see screenshot below. Click the Help button for further assistance.

Nextcloud
This articel describes how to backup Nextcloud to S3 Storage hosted by HDD-Housing.
Configure HDD-Housing S3 Storage in Rclone
1. Configure S3 Remote
Install rclone and run:
rclone configFollow the prompts to create a new remote (name it mys3) using the s3 provider.
2. Create a Backup Script
A proper backup requires a database dump before the transfer. Create a script (backup.sh):
# 1. Put Nextcloud in maintenance mode
sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --on
# 2. Dump the database (example for MariaDB)
mysqldump --single-transaction -u [user] -p[password] [db_name] > /tmp/nextcloud-db.sql
# 3. Sync to S3 (Data + Config + DB Dump)
rclone sync /var/www/nextcloud/data mys3:my-bucket/data/
rclone sync /var/www/nextcloud/config mys3:my-bucket/config/
rclone copy /tmp/nextcloud-db.sql mys3:my-bucket/database/
# 4. Turn off maintenance mode
sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --off
