We are planning to increase our mail storage space by enabling HSM and using a cheap RAID5 NAS for storing those old messages that are never needed but are important for some users.
However, I have a doubt about backup strategy.
Does zmbackup include those contents in incremental or full backup?
If we use HSM we could increase a lot our storage, but our backup repository would be unable to store that increase. So the question is if zmbackup also includes HSM or if zmbackup leaves secondary storage out of backup.
It appear there is no zmbackup flag to include or exclude secondary storage.
Thanks in advance.
