Hi i have installed a proxmox backupserver, and i have startet a backup to a zfs disk
the zfs disk is mountet via the webpannel.
i can see the backup takes long time i hav e vm with 64GB and the process takes now 2h, i can also see the networktrafik is:

a other vm has this nettrafik:
INFO: 27% (4.4 GiB of 16.0 GiB) in 2m 16s, read: 226.7 MiB/s, write: 12.0 MiB/s

INFO: 37% (5.9 GiB of 16.0 GiB) in 2m 39s, read: 152.0 MiB/s, write: 21.3 MiB/s

sometimes very low, the network is a 1Gib net, the backupserver is a HP Microserver Gen10

is this normal?

i have also a nfs server and with the nfs server i have 100-250MiB+ networkspeed
all servers have 1G ethernet
