Example for sync data
10.0.0.2:/source → 10.0.0.1:/mnt/pool/data
Source server
Source server Ubuntu 24.04 Linux - 10.0.0.2
apt install nfs-kernel-server echo "/source 10.0.0.1(rw,sync,no_subtree_check,no_root_squash)" >> /etc/exports cat /etc/exports exportfs -a systemctl status nfs-server
Destination TrueNAS host
TrueNAS 25.10 - 10.0.0.1
sudo bash mount 10.0.0.2:/docker /media rsync -avP --delete /media/ /mnt/pool/data/
That is just one of the many ways to do that, the next option is to set up NFS on TrueNAS side and do rsync on the servers.
If not TrueNAS, just other Ubuntu host then
apt install nfs-common mount 10.0.0.2:/docker /media rsync -avP --delete /media/ /mnt/pool/data/
