  • Retention Time
    Posted: 02-28-2017, 4:35 AM

    i'm using Simpana 10 R2 SP12
    We have a Storage Policy for B2D with a retention time 6 days and 1 cycle.
    Now we have not enough space on the B2D storage.
    Make it sence to minimize the days eg. to 3 and 1 cyle ??
    Because one cycle = 7 days...??

    Hello Dennis,


    You are correct to assume that the DAY criteria will not affect this as you have a weekly schedule and you need to retain one CYCLE. BOTH criteria have to be met and the cycles are aging in their entirety (full and dependend incrementals).

    Your better options would be to:

    1. Ensure you have set proper global filters

    2. Verify the data you want to protect is actually critical and you have a reason to retain it

    3. Also check if the data aging should also run in the evening before your backups to ensure you have the most available space (or whenever your backups are scheduled) as this is by default only noontime.

    4. Make sure you have your AUX copies running so any job that's "stuck" is going to be resolved (right click the Storage Policy Copy and check "Media not copied")

    Obviously there's a few reports you should run (media retention etc.) to make sure this is all you have to action. Verify that there aren't any old backups that may be left on the disks.


    I hope that get's you started.

    1. What do you mean with global filters?
    3. OK, where can i set this? T think we have the default settings.

    Hi again,

    Global Filters are used to exclude content from backups that is "useless" for example temporary or log files that you wouldn't want to restore or that get replaced upon reboot. (Think what would happen if you backed up the swap file on a Windows machine).
    Excluding this unwanted data can speed up your backups and obviously make them "smaller"

    As far as the data aging goes I'm almost certain you have default settings (Simply check in the "Scheduler" window and filter it if need be).

    The problem I am trying to address is simply that a day is based on 24 hours (yes I know that sounds silly:).

    If a backup just meets retention at 12:00 noon time when the data aging runs, the old data will still be kept. If you schedule another right before your backups it will be pruned off, thus giving you the maximum storage available.

    The easy way of scheduling another data aging is to right click on the Commserve entry on the top of the browser tree and select data aging, you can then set up a schedule in the Wizzard.

    Let me know if this clarifies.
