Set varbinary_strip_trailing_zeros to off to enable the replication of trailing zeros in varbinary values.
The default setting of on strips trailing zeros from varbinary values. The default setting has been the behaviour of all Replication Server versions earlier than 15.7.
You must set varbinary_strip_trailing_zeros at the server level with configure replication server. You need not restart Replication Server, or suspend and resume connections for any change in the parameter to take effect.
