    Default does dedicatd parition for mails make sense ?

    Hello

    I am going to partition the OS for Zimbra (OSS/FOSS). My idea is to have ZCS saved it's mails to a dedicated partition (in oder they would survive a possible reinstallation of Zimbra)


    Questions:
    Does a dedicated partition make sense for that purpose, or is there no way than to take/shut Zimbra down, backup the mails to a folder at my choice and to import them after reinstalling Zimbra (from scratch)?


    Thank you for your feedback! John

    Why not just backup the whole of the /opt/zimbra tree ? When you say re-install ZCS do you mean completely ? ie. No /opt/zimbra at all ? Only reason I see for segregating the datastore is from a performance perspective or SAN/NAS mounting.

    Separating the different bits of the system is a good idea, as it allows you to balance the IO across disks. Having separate disks (or arrays) for the OS, for /opt/zimbra, for /opt/zimbra/store, /opt/zimbra/log, and /opt/zimbra/backup is a good idea.

    Personally, I like to put the OS onto CF or USB sticks using software RAID1 (configured to boot from either disk). This rarely requires more than 2 GB since a minimal install with SSH is all that's required.

    Then you can dedicate your fastest disks/arrays to /opt/zimbra/store and /opt/zimbra/log. And your biggest disks/arrays to /opt/zimbra, /opt/zimbra/backup, and HSM.

    At the very least, /opt/zimbra/store and /opt/zimbra/backup need to be on separate disks.

    Thank's a lot for your advise. I will make the suggested partitions in the production environment.
    At the moment we intend to play with Zimbra with some few users.


    Question:
    If you had only 20GB space on SAS disk available, how much space would you
    assign to the following partitions?


    /opt/zimbra/store
    /opt/zimbra/log

    /opt/zimbra
    /opt/zimbra/backup



    Thank you very much in advance for you help!
