@olivierlambert Remote storage - hard drive in raid 5

@olivierlambert After switching to 1f325, the problem remained. For random virtual machines, a full backup is created instead of a delta and all deltas are deleted.

Job.
Delta Backup
Remote - Windows smb share.
VMs to backup - All virtual machines on all servers

Schedule
Name - vms
Retention - 30
Health check - no
Force full backup - no

Nothing in the logs

@olivierlambert I just upgraded to 1f325, I can't say the last commit. I will observe the behavior of backups for a couple of days. Thanks

@olivierlambert I read the article, the problem is still there

Xo-server 5.98.1. Delta Backups. Backup retention 30. Periodically, a full backup is created for some virtual machines instead of delta, and all backups are deleted. There are no errors

@olivierlambert

You should wait for our next-gen export mechanism that will be a lot faster since not relying on VHD export

If I start using XO now, then I will only need to update it later to get the next-gen export mechanism?

I want to maximize the backup speed. I have synology (active-active), xсp (active-active), I put bare-metal xoa (balance-alb) for testing, I also tried others, for example, 802ad. Separately, aggregation works in the network, all interfaces are involved, tested through iperf. But together the xcp->xoa->synology only one interface is always used on the xoa server, the second one is idle

does xoa work with balance-alb?

@olivierlambert Will it be necessary to update xcp-ng for this, or will it be enough to update xoa? Where can I read about this update?

I created a Bare metal XOA server. I want to use it for backup. Tell me if the backup speed from my XCP-NG servers will depend on the processor power, the throughput capacity of my network card in the XOA server?

I've been reading for a long time that xoa is working on the zstd compression functionality in delta backup copies, is there any news in this direction?
