  • hi,

    anyone has DPM storage calculator for SQL Server 2005 database. 

    i don't understand formula For SQL Server data:

    ·    Data source size x (1 + log change) / (alert threshold - .05)

    its gives me  very big weird  figures.

  • I have just upgraded to 2010 and thought the autogrow feature would be really great.

    Unfortunately is it consuming huge amounts of space, especially for SQL DBs.

    I have some email archives where I have 4 DBs per year, 4 years, each one about 60-100GB. I allocated about +10% for the replica and 5GB for recovery. Overnight they grew, I'm guessing it added 25% to the DB size for the replica and made recovery over double the DB size.

    So now instead of something like 110+5 I have something like 125+250. Multiply this by 16 and it is now taking 5TB to protect about 1.5TB of static SQL.

    Any way to adjust to 10% instead of 25% and reduce the replica ?

    At the moment I cannot see any choice but to disable autogrow and go back to doing it manually which is a shame.

  • The 25% or 10GB whichever is greater is not adjustable.  however, something went terribly wrong if the RP volume grew from 5GB to 250GB overnight, that implies that something is completly overwriting those database files.  How could they be considered static, yet change that much over night ?
