Consider a file system in which multiple users/clients can
access the data from the disks
over storage network. Assume each user/client has its file system
and considers its storage
disks (shared with other clients) as local.
(a) Explain how this file system is different as compared to NFS
(Network File
Servers).
(b) What are the major advantages and disadvantages of this type of
file systems (do
not repeat the points mentioned in answering the part-a)?
a ans:
Pros
The professionals of victimisation NFS for backups include:
NFS does not need authentication, therefore you do not ought to code in usernames and passwords.
NFS is extremely quick over Gigabit local area network networks.
NFS is typically associate on the market choice on a NAS device.
NFS exports mounts directly into the classification system on mount points. terribly simple to repeat information back and forth victimisation native copy commands like cp and vmkfstools.
Cons
The cons of victimisation NFS for backups include:
NFS doesn't have any native support in Windows. needs Services for UNIX system. Not suggested.
NFS isn't as secure as different choices, because of lack of authentication and encoding.
B ans:
Advantages:
1)Backup
2)Compactness
3)Editing
4)Sharing
5)Remote Access
Disadvantages:
1)Data Inconsistency
2) Integrity Problems
3) Concurrent Access Anomalies:
4). Security Problems
5)Limited Data Sharing
