Hello,
First of all sorry if i make some english mistakes (i'm french and not so good at english)
We are currently looking for a better backup solution for our cluster.
Indeed we have a five nodes cluster on proxmox running about 25 qemu VMs.We actually use the integrated Vzdump Backup solution for all Vms at night but it's taking too much time for vm with large disks (about 15 hours to do the whole backups).Some Vms With about 500 GB diks can take 5 hours to backup
For more precision our VMs disks are on an equallogic SAN with 3 GBits ethernet links and we use LVM over the ISCSI connection.The backup are done on a NFS storage on a Synology.The total of VMs disks size is about 3To.
When looking at backup logs i can see for example a 500 GB vm is backuped in 4 hours in 50MB/S and the archive is 177 GB.
We also need to duplicate those backups to another site where we have a another proxmox cluster as a recovery site.So if doing full backup we have about 1,5To to transfert by our 100Mbps Fibers connexion so it would take about 41 hours (10 MN/S) to transfert it which is not possible.
So we are looking for a solution to be able to do backups and repplicate all in the off-site at 8 hours or less (zfs pve zsync?incremental backups like in veeam for vmware would be better but i didn't found anything doing the same for proxmox)
If someone have a solution it would be greatly apreciated.
Thanks all.
