Hello there,
Recently I’ve set up Nextcloud VM, which is hosted on XCPng. The VM has 2 drives, one on ssd for system and database. The second one is on ISCSI LUN stored on Synology (1 gb connection) .
It all works great. The system is fast, responsive, awesome.
But before I start putting my data there, I want to make sure my files are safe and I can recover them. The VM and database on it I don’t really care, easy to rebuild in home scenario and I have copy of ready image anyway. The problem is with data.
- Using Backup tools on XCPng
Unfortunately the ISCSI DISK has to use Thick provisioning, no other way around it, which means I’d have to back up terabytes of air (if I had enough storage).
- Using Hyper backup on Synology
It’s useless for LUNs. It allows to “back up” to shared folder on the same device or different Synology. No option to back up directly to cloud.
- Using synology active backup for business agent
This maybe an option, but seems like a tool for local trusted network, not server exposed to the world (fully air gapped by firewall between my LAN).
- Rsync directly on ubuntu VM
Maybe? But it is a sync tool rather than backup.
At this point I am tempted to go NFS, but I choose ISCSI because of authentication and good performance, not sure if there are any other downsides compared to ISCSI.
Any thoughts? How are you backing up your LUNs and recovering? Maybe I am missing something.
EDIT: Fixed some errors.
