Hi I am experimenting with proxmox for some months now and I can say that there are a lot of to learn about this tool!
The core system that I am working on is a some VMs with 1 disk on local-lvm(LVM-Thin), some others on a disk1(LVM) and I have a production VM that has 3 disks.
I also have a second Node that I want to use for backup and the other Node that is less powerful but it can store some backups.
My goal is to have as much as possible uptime ( I have seen HA ) and not to lose data.
For the simple VMs with the one drive, I have tried to move them to the ZFS disk. The method that I used is to back up them and then restore them to the ZFS disk.
Note: I tried to clone them to the disk but it took a lot of time. I am not suggesting it.
The problem that I faced there is that ZFS is using all the Ram that he can and my VMs are a little bit slower. BUT I was able to use HA with replication for having uptime and the data that I lose isthe last 15 minutes+ the time for the VM to go to the other node.
But I hit to a wall when I tried to do this with the production node. Because it has 3 disks I couldn't move them all to ZFS. I also I did not space for that in my disk so I start looking for others solutions.
I also have tried to use NFS for storing hard backups but this does not cover the possibility of fast or automated discovery. So it is a bad solution for me.
I am thining to move with ceph but I do not know. I see that a lot of people say that they have a learning curve.
A other thing that I am thinking of is that I could have the data to separate disks of the VMs and this could make my life easier for the backups but I do not know where to look. I am thinking that seafile could help me synchronize data to different disks but I haven't seen any implementations on the internet.
What the community does?
Why we can not have any standard process for the backups?
Can someone help me, please?
Thank you for your time,
