Why do most file systems maintain redundant copies of their superblock throughout the disk?
What will be an ideal response?
The superblock maintains the integrity of the file system by storing the location of the
root inode and pointers to data structures tracking disk free space. Thus, if the superblock is
damaged, all data stored in the file system could be lost. Maintaining multiple superblocks on
disk prevents this from happening if the primary copy of the superblock is lost or damaged.
