Let say I only have space for 2 years of email but need to keep the emails for 10 years.
Any preferred method to "archive" the archiving emails to be restored when needed?
I'm thinking to do full backup every 2 years and set retention policy of emails to 2 years.
Then I look into zmrestore command and couldn't find any option to choose which full backup to restore.
Please help to suggest other way to do this.
