Microsoft windows operating systems possess numerous features including virtual memory, multitasking, graphical user interface (GUI), and relevant support for the peripheral devices in relation to the operation of the computer systems.
File System
The file system of Linux Operating system is hierarchical in nature in that everything starts with the root directory and then expands to the sub-directories (Vasile p. 80). This is an indication that Linux puts all the relevant partitions under the main or root directory through mounting them under specific directories. This system is essential since it offers the opportunity for the computer users to choose on mounting the file structures in another partition. This is possible under minimal registry and system error in the process of moving the executable and data within the Linux Operating System.
Microsoft Windows has the capacity to support file systems in the format of NTFS 5, FAT 16, and FAT 32 (Lone et al, p. 172). The ability to support these file systems offers the opportunity for organizations and individual computer users to choose on the version to install in relation to meeting the needs and demands of the organizations and relevant clients. The filing system is associated with the registry and systems error in relation to movement of transfer of executables or data from one base to another within the operating system. Mac OS X supports the following file systems; UDF, UFS, NTFS, MSDOS, and ISO9660. This is crucial towards meeting the requirements of the organizations and individual computer users.
Security Controls on the file system
Linux adopts the use of encryption as a move towards ensuring security of the computer systems.

This limits the essence of intrusion by external sources in relation to the organization and individual computer users.
Backup and Restore
All the three operating systems possess unique steps in relation to backup and restoration of the files within the programming and relevant applications. This is vital to enable organizations and individual computer users the opportunity to recover their files in case of any interruption with the system. Restoration is also vital to monitor the essence of external intruders trying to access the system without authentication of the user of the computer. This reflects on the protection levels in the Microsoft Windows and Mac OS X operating systems.
Licensing
Majority of software products is licensed instead of ownership. This means that through purchase of the software does not guarantee the ownership. It is still usable under that terms dictated by the licensing agreement. This is through entitling them to an unlimited application with a certain number of installations. The tangible software is an asset protected through the contract law and the copyright. The legal right of the software application is granted through the conditions and terms dictated by the license purchased. Irrespective to the incurred price when purchasing the software, it must be manageable to enable the assurance of compliance to the contractual and legal license conditions and terms. The deployment of a software product to a device requires a license irrespective of the software use or not (Rittinghouse Pg 5).
Software license management structure
The implementation of an effectual software license framework provides the Systems Administration with a structured approach with the control and management of risks in the process of maintaining the critical asset of the clients. It is significant realizing that the process is continuous, and for its effectiveness, an equal contribution of the clients is necessary with the policy covering the regulatory requirements and the process. The framework should not lack any of these elements in order to help realize all applications to benefit the administration (Rittinghouse Pg 5).
People
They form the resources required for the completion of the necessary tasks for proper implementation of the framework with maintenance on an ongoing basis. It also requires the employee’s commitment within the system administration to handle the procedural tasks developed as part of the system framework.

Accessibility to the systems administration information system is a subject to the Client System Access Request Software Policy. It is the policy under the codes and conduct proposed during the software purchase protects the information asset. This allows the clients accessibility to the requirements and clearance levels inclusive of files, internet and the applications. The accessibility and disclosure of the agreement information on the purchased software should be only in accordance to the applicable interest regulations and laws stipulated to protect the software. This is ensured through the creation of a conventional user account with detailed password. This is to ensure there is an ethical obligation to protect the client’s confidential information. The purpose of the security access register is to establish the responsibility of the user in safeguarding the purchased software and information on its application. The accomplishment of the policy requires issuance of specified system ID that is not sharable or utilizable by anybody outside or inside the client’s system administration inclusive of the staff (Rittinghouse Pg 31).
All the information printed including software microfiche, magnetic and optical storage media is a property recognized under the license policy as confidential. The client’s departmental head has the responsibility of notifying the system administration for any security breach in the event of adjustments to provisional services.
Infringement of intellectual property
The trademark, copyright and the infringement of the purchased software are strictly under prohibition. The license provided extends to the protection of the software accessibility. Copyright infringement of the software purchased in prohibited given that its ownership is still non-dependent hence treated as liability crime. The client purchases the right to apply the software on computers under the protection of federal copyright laws. The copying of the software at any given time to apply to a personal computer is an infringement. The exposure potentially to any computer virus with impact to the network of the client’s computer is an unapproved software internet downloading. The client is given the right through the license details to monitor for any possible compliance without the prior notification to the system management (Rittinghouse Pg 40).
Electronic signature
The signatures are only approvable to clients with appropriate levels of security in the specified software application module. For any given legal reasons, the client using the purchased software has to adhere to the set up criteria in support and maintenance of of signature authentication. The client agrees to the license requirements through writing and should not share outside the agreement terms (Rittinghouse Pg 40).
The breach of the given policies inclusive of sharing identifications, the access codes and the password is a violation to the terms of the purchase. This aids to the subjection to disciplinary from the system administration inclusive of access termination with violators being subject to criminal liability.

The techniques and tools available will enable the operation of backup and recovery to suite the specified client needs. During the installation of the software, BRMS registers with initialization automatically attaching to the client system platform creating a corresponding information entry. It is significant attaching the necessary devices for the client before the installation of the backup and restore media service. Addition of devices after the installation enables running of the initializing process for the registration of the new devices using BRMS. The usage of the BRMS initials (INZBRM) command is necessary in accordance to the OPTION (*DATA) parameter. The installation of the MSE (media and storage extensions) should be considerably in the clients system before the installation of the BRMS for registration to exit points (Rittinghouse Pg 106). The following diagram illustrates of how BRMS backup and recovery process through media storage labels. Control groups, policies and the software devices links up the recovery and backup process.
How What Where to Store
