Need for verify in remote PBS?

[julian]

I have a primary PBS with SSD syncing to a remote PBS with HHD. Running the verify task(s) on the primary is fast, but on the remote is quite slow.

I wonder if it is strictly necessary to do a verify on the remote too? As this is just a 1 on 1 copy of the primary. If on the primary all is OK then it should be OK on the remote too, all data transfer itself is already checksumed by the transport layer, or am I missing something? Remote also is on ZFS.

How do others manage this?

What means fast and what means slow?
I wouldn't go without verify in case data is corrupted or manipulated after the Transfer.

Also, verifying in every pbs node helps to increase safety of stored data, because there could be issues in local datastore (it happened to me).
