Differential Backups saved to another drive set

[kproctor]

I created hourly, daily and weekly replication tasks that backup drive set 1 to drive set 2. Unfortunately, I can't see how long backups are kept. Are these single backups? Is there a method to keep:

• 2 days of hourly backups
• 7 daily backups
• 6 monthly backups

Is there a differential backup that supports target destinations? TY in advance.

See "Remote Replication" in the TrueNAS manual at https://www.truenas.com/docs/core/tasks/replicationtasks/remote/ for the instructions to perform all the tasks you asked about if Drive Set 2 is on another machine. If it's on the same machine, see "Local Replication" just before the Remote pages.
