Advantages of creating several POSIX file systems

Setting up several POSIX file systems has the following advantages:

• Greater data security:
  If one POSIX file system is destroyed, the remaining POSIX file systems are retained. Individual POSIX file systems can be selected for backup.
  Unmodified POSIX file systems can be excluded from a backup.

• Greater data protection
  Only currently required POSIX file systems are mounted and made available to the user.

• Improved clarity and structuring
  A POSIX file system can be set up specifically for a user or for a project.
