Problem/Justification
When sending replications offsites using replication tasks, there is no option to specify the beginning and ending time.
Currently we take snapshots every hour daily with a fixed start and end time for the task. Those snapshots are then aggregated and scheduled to be sent offsite using a replication task at 3 hour frequency.
Impact
TrueNAS will not constantly pool the snapshots to check for any available snapshots to send off site.
User Story
Just like how easy it is to setup “Being” and “End” times on periodic snapshot tasks, the same exact fields can be added on replication tasks.
