  • Calculation help needed for backup and archive
    Posted: 11-11-2016, 2:06 AM


    Total email users 5000

    Each user is at 1GB mail box size

    Need to backup on weekly basis, monthly basis and yearly basis.

    Archive on yearly basis for 5 years


    Total Email Server Storage is about 10TB


    Recommend the Media Server Specification and assuming I need to backup to disk, say using external disk or NAS, what will be the storage size for backup and archiving for 5 Years.

    So, roughly 5TB of email data to be backed up and archived.


    Are you using deduplication?  I assume you would.


    What is your archive rule? Anything older than 365 days?


    When you say "Total Email Server Storage is about 10TB", this includes free space on disks/drive?
