Replication and the 35 day scrub

[dneculai]

Hello,


Freenas has a 35 day scrub job configured in /conf/base/etc/periodic.conf like this:
daily_scrub_zfs_enable="YES"
daily_scrub_zfs_default_threshold="35"

How ok or recommended is for this job to run on a replicated system? ie, replicating from Server1 to Server2 and keeping the scrub running every 35 days on Server2.
Also would it be enough to just run scrub on Server1 where the initial data lies?

Appreciate any input on this,
Regards

Scrub should run on both sides, it prevents silent data corruption.
