Is there anything special to set up for backing up a large ZFS resource library?

I have a 30t resource library. Every backup is always very slow.
Is there any special setting that can make it backup faster?
`INFO: Upload directory '/mnt/vzsnap0' to 'root@pam@10.255.0.208:8007:pbszfs1' as root.pxar.didx`
In fact, I looked at the use of disk and the use of network, and he just stayed here Nothing was done

Using a VM with zvols instead of a LXC with datasets might be faster. LXCs don't make use of dirty bitmapping, so even if not much has changed since the last backup, PVE would need to read the full 20TB to look for changed data.

I directly regard it as an NFS shared pool. Can I use PBS for backup?
