Issue



When creating a Deduplication Storage Folder (DSF), a warning pops up indicating that there is not enough physical memory available to support the creation of a Deduplication Storage Folder. 


Error



This computer does not have enough physical memory to support a deduplication storage folder.  1.5GB of physical memory is required for each 1TB of deduplication storage, with a minimum requirement of 8GB of physical memory.


Solution



This warning pops up to ensure that the system does not get starved for memory when supporting a Deduplication Storage Folder (DSF).  The amount of memory required to support a DSF increases as the amount of data placed into the DSF increases.  While the system most likely has enough memory at the beginning when there is little to no data in the DSF, it is important to ensure that there will be enough memory to support the DSF up to the point where it is fully populated.  Solving this problem now while the deduplication folder is still small is much better than waiting until the deduplication folder is full, and unavailable because the system is starved for memory.  Please see the Best practices for Backup Exec 2010 Deduplication Option document www.symantec.com/docs/HOWTO21767 for details on the memory requirements for the Deduplication Option.
