Inodes are data structures that hold information (including permissions information) about files on the storage
system. Every file in the file system is uniquely identified by its inode in the same file system.
Note: The inode number for a file in a
Snapshot copy is the same as the inode number
for the corresponding file in the active file system. As a result, some programs on
UNIX clients consider the two files to be the same. For example, if you use an older version of the GNU diff program to compare the
two files, it might not find any differences between them. However, newer
versions of GNU diff should work.
In a few cases, if you try to restore a file from a
Snapshot copy,
you might see the following error message:
cp:.snapshot/xxx and xxx are identical.
To ensure that the two files have different inode numbers before the copying or
comparison, copy one of the files to a different name.
