Hi list, hi Proxmox,
Has someone looked at the domainname of the original poster?
And the website?
host www.t8.ru
www.t8.ru has address 195.208.1.108
host t8.ru
T8.ru has address 195.208.1.108
t8.ru mail is handled by 30 mx01.lancloud.ru.
t8.ru mail is handled by 10 mx02.lancloud.ru.
t8.ru mail is handled by 5 mx01.lancloud.ru.
t8.ru mail is handled by 20 mx03.lancloud.ru.
geoiplookup 195.208.1.108
Continent : Europe [EU]
Registered country : Russia [RU]
Country : Russia [RU]
Coordinates : 37.6°E 55.7°N
Time zone : Europe/Moscow
It looks like a Russian ISP. Head office in Moscow.
Is it appropriate to provide technical support to a Russian ISP on this
list or in any otherway?
My personal meaning is that it is _not_ appropriate. Supporting such an
outrageous aggessor.
Please consider to stop doing that.
Best regards
Stephan

Have you tried to copy a large file directly from the host(s) to the nf
server, how's the speed on that?
Yes, I try copy large file iso with rsync and the speed is no more
than 180MB/s - 210MB/s
Have you checked if there's a bandwidth limit set for the backups in pve
datacenter options?
Yes, no limits Bandwidth set in Options.
Try running a single, manual backup on a specific vm to the nfs server,
how's its speed compare to the scheduled backups?
Yes, in GUI I try the start one backup, the speed when start is up
after is falling to same speed:
In attach is from one host when is start backup and show speed to
Synology.

Hi, to all.
In our PVE cluster have 5 hosts with ceph storage on all hosts disks.
I setup backups to save on Synology with NFS storage.
For 2-3 moths right now backups load very long time and not fast to
finish backup from all hosts.
If we change the MTU from default 1500 on Synology and on hosts to 9000
MTU is possible to make it fast.
Synology and the hosts connect to the Fiber Optic 10GB switch but the
mtu on switch and on the hosts for now is default.
If I ping to Synology from hosts :
ping -s 9000 -d 192.168.8.23
PING 192.168.8.23 (192.168.8.23) 9000(9028) bytes of data.
9008 bytes from 192.168.8.23: icmp_seq=1 ttl=63 time=1.03 ms
9008 bytes from 192.168.8.23: icmp_seq=2 ttl=63 time=0.223 ms
9008 bytes from 192.168.8.23: icmp_seq=3 ttl=63 time=0.229 ms
I have the answer.
When I test connection with between the hosts PVE connect :
iperf3 -c 10.10.29.16

But the speed to backup to NFS is very low.
Can some one give me suggestion how I can make faster the NFS
backup on
hosts (all hosts is now production).
