Hi,
We have Exchange 2013 with Hybrid setup with O365.
We have On premise exchange 2013 servers with 3 copies of primary Database & Single Copy of Archival DBs.
Now we have to frame backup policy with Symantec Backup Exec which has to backup our primary & Archival DBs
In 2007 exchange, before migration to 2013, we had policy of DBs - Weekly Full backup & Monthly Full Backup
Please suggest what would be the best possible backup strategy we can follow with 2013 DBs.
That too, especially for Archiving DBs
Our Archiving Policy are - 3 category - Any emails older than 6 month OR 1 Year OR 2 Year should go to Archive mailbox.
Keeping this in mind how to design the backup policy ?
