In UNIX, each time a file is created, there is a corresponding I-nodes, these continuous I-nodes form the I-nodes table contains all the file index numbers in the file system. When a user accesses a file, UNIX first uses the I-nodes table to raise the corresponding file I-nodes number, and then accesses the file data. I-nodes is equivalent to the control (configuration) of a file) information ISTAT/filesystem # Smit FS mkfscrfslsfsrmfschfs # chfs-a size = + 100 m/test # chfs-a size =-100 m/test
Snapshot: Instead of "moving" the entire file system to the location where the snapshot is stored, the snapshot just copies the "changed" content, that is, only copies the changed database to the snapshot point, therefore, snapshots only occupy a dozen percent of the original file system space.
