Question 1: does distributed file systems eliminate need for backup
Distributed file systems are implemented over several computer servers that are located in different places enabling sharing of data across the various computer networks. The file system allows implementation of replication and access transparencies. However, the distribution process does not eliminate the need for data backup. Data backup is necessary because in distributed file systems data being shared may exist only in one computer and if lost, all other computers will not be able to access the same data (Girone, 2015). Distributed file system share data when needed by another computer, however, this does not provide for data redundancy. Replication and access mechanism supports the backup of data, but not replace backup. The arrangement provides for means using data that is backed up without experiencing data inconsistencies.
Question 2: difference between disk quotas and file server resource manager
A disk quota is a systematic administrative mechanism used by computer systems to allocate memory space on NTFS volumes (Cho, 2015). File server resource managers is a suite that allows control and management of quantity and type of data stored on servers. The site provides different services which include:
Automatic quota generation feature.
Provide storage reports on disk usage file screening activities and all other activities that are involved in file management.
Provides for easy backup and restoration setting which helps in the recovery of computer data in case of inconsistencies.
Requirement for implementation of file server resource management
A server
A network
Disk storage space
Power shell
