Log shipping durability trade-off

Log shippers lose events when the aggregation endpoint is briefly unavailable. Which change improves durability?
Options
  1. 1Increase the network timeout so the shipper waits longer before giving up on a send
  2. 2Reduce log verbosity at the source so far fewer events need to be shipped at all
  3. 3Persist logs to an on-disk buffer with acknowledgement-based truncation
  4. 4Switch the transport to plain UDP so failures do not block the shipper's event loop
