Prevent Access to Deleted Files (Data Shredding)
The Data Shredding feature overwrites purged disk blocks with random
patterns of hexidecimal characters. This prevents unauthorized users from
using a disk editor to access purged files. You can place up to seven data shred
patterns over deleted data.
Set Up User Space Restrictions
User space restrictions let you limit the space users have on volumes. This is
beneficial for systems that accommodate a large number of users, such as
students. When you create volumes, you can select the user space restriction
option in ConsoleOne.
Set Up Directory Space Restrictions
Directory space restrictions let you limit the space users can have in a
directory or subdirectory.
Use CD-ROMs as Read-only Logical Volumes
NSS has full CD-ROM support for ISO9660 and Macintosh* HFS formats.
No Additional Memory Required for Mounting Volumes
When you mount volumes using the traditional NetWare file system, it scans
every file and directory during the mounting process. Then it loads all the files
into memory for quick access. If you increase the number or size of files, you
need additional memory to maintain the performance level you want.
NSS does not require large amounts of memory to mount volumes because it
does not scan the entire file system during the mounting process. After the
mounting is complete, NSS does not load files into memory until you access
them. Therefore, no additional memory is required when you add files and
mount volumes.
