Drive backup between 2 proxmox servers

[volkanos]

Hi,

I have 2 promox server in a cluster. I search a solution to copy all of my data on 1 drive on my first server to my another one 1x by mont. I found any solution to make a backup on 2 promox server in the interface except what is consern VM/CT.

Which solution you use to make a backup?
Rsync on OMV VM?
Rsync directly on proxmox?
Rsync on a container?

Another solution?

Thanks.

Hi,

If you use ZFS on both hosts, you can use pvesr to replicate the data.[1]
But if you were really talking about backup, I would recommend you to install a container with Proxmox BS [2]
on both hosts and sync the backups.

Rsync vdisk direct is dangerous and can produce corrupt backups on the dest host.

Thanks for the reply wolfgang.

I will try to explain better

Too simplify my server config, I have two servers in a cluster with same configuration:
2x Ssd (for proxmox/vm/ct)
1x 10TB ZFS (for my data (personal video/photos etc)) This drive is mounted with samba directly on proxmox server to give access has more than one vm.

I try to find a solution to sync my 10TB on server1 to server 2, this data content only my personal videos/photos etc. Is this one I want to sync.

I looked for storage replication and Promox BS and this make a backup of server and vm/ct? I can't replicate/copy my personal data. Or there is something that I didn't see because I don't find a solution.

Maybe ZFS has a solution?

My drive is shared directly with samba.
If I mount the share in a ct/vm with smb and use rsync? This not use vdisk. Good solution?

If both drives use ZFS you should use "zfs send" and "zfs receive" to replicate the pools. I think pvesr will use the same commands for replication, so use that.

You can sync the zfs dataset with pve-zsync.[1]

Thanks all! I tried zfs send/receive and pve-zsync,

I will use pve-zsync. This command to create and sync dataset

pve-zsync sync --source Data1 --dest 192.168.0.254:Data1 --verbose --maxsnap 4 --name Data1

but I will create recurring sync job and modify the cron job to make sync every 2 weeks and keep 4 snapshots.

pve-zsync create --source Data1 --dest 192.168.0.254:Data1 --verbose --maxsnap 4 --name Data1 --skip

Last question:
Just to confirm this command create a incremental snapshot?? That what I see yes, it's an incremental.

Thanks

it's an incremental.

If there is the possibility for increment sync, it will do increment sync.
