Snapshot restore will take a snapshot ID and restore the associated snapshot to the target path. - Looks up the manifest with the snapshot ID - Gets the snapshot root entry - Copies the snapshot from the root entry to the target path Because it uses the parent manifest with the copied permissions, the restored directory will have the permissions of the original source directory.

The target path must not exist and it is created by the restore command. The
|
|
case when the target is the root directory in the local machine is an exception,
|
|
in this case no attempt is made to create the root directory and the contents of
|
|
the source directory are copied to the local root directory.
|
|
The restore command conservatively refuses to overwrite previously existing
|
|
files or directories.
|
|
|
|
The source to be restored is specified in the form of a directory ID and
|
|
optionally a sub-directory path.
|
|
|
|
For example, the following source and target arguments will restore the contents
|
|
of the 'kffbb7c28ea6c34d6cbe555d1cf80faa9' directory into a new, local directory
|
|
named 'd1'
|
|
|
|
'restore kffbb7c28ea6c34d6cbe555d1cf80faa9 d1'
|
|
|
|
Similarly, the following command will restore the contents of a subdirectory
|
|
'subdir/subdir2' under 'kffbb7c28ea6c34d6cbe555d1cf80faa9' into a new, local
|
|
directory named 'sd2'

'restore kffbb7c28ea6c34d6cbe555d1cf80faa9/subdir1/subdir2 sd2'

' kffbb7c28ea6c34d6cbe555d1cf80faa9' or
