I have a replica on a slow DSL link, with smaller snapshots it completes fine however a larger 300GB never completes. The server pushing in between 10-40GB data per day and gives up.

On the sender:

root 15638 0.0 0.1 48620 4576 - S 1:38AM 0:44.59 zfs: sending backup/corp@auto-20200507.0700-4m (6%: 16538124128/244351708768) (zfs)

On the receiver:

root 39357 0.0 0.1 27716 3048 - Is 1:38AM 0:00.33 csh -c /usr/bin/env lz4c -d | /sbin/zfs receive -F -d 'backup' && echo Succeeded


I have found some similar threads:


Here they suggest using this mbuffer but it is not part of FreeNAS and I rather don't install it if I don't have to. When creating the replication there are no options so I wonder if anyone managed to solve this. I don't care if it's slow and it takes weeks to replicate just to make it work.
