lizardfs-makesnapshot - make lazy copies
lizardfs makesnapshot [-o] [-f] 'SOURCE'... 'DESTINATION'
makesnapshot makes a “real” snapshot (lazy copy, like in case of appendchunks) of some object(s) or a subtree (similarly to the cp -r command). It’s atomic in respect to each ‘SOURCE’ argument separately. If ‘DESTINATION’ points to an already existing file, an error will be reported unless -f (force) or it’s alias -o (overwrite) option is given.
The new object exists only in metadata until changes to the data are done which will trigger creation of chunks for the changed files or removing metadata entries for erased chunks, unless the trash feature is utilized.
NOTE: if ‘SOURCE’ is a directory, it’s copied as a whole; but if it’s followed by a trailing slash, only the directory content is copied.
