allocated for shared folders), click Finish .
To allocate more space for shared folders, select Allocate more space for shared folders and then
specify how much space to allocate (either All available disk space or Specified disk space ). If you
select Specified disk space , enter the number of gigabytes to allocate for shared folders (the mini-
mum is 1 GB). Then click Finish .
8. When the confirmation message appears, click OK .
Note: You can expand the amount of disk space allocated for shared folders later (as long as free
disk space is available), but you cannot reduce it without reconfiguring your disks and losing
all of your data.
If you plan to back up computer disks to your storage system, it is recommended that you
use the minimum amount of space for shared folders, back up all the computer disks that
you plan to protect, and then expand the space allocated for shared folders. This ensures
that adequate space is available for backups.
