snapshots

Is it possible to mirror the two directories without overwritting the files in destination directory with new/changed/deleted files. Something like snapshots.

Example: Copy the source directory with all files and sub-directories to destination directory, but if destination directory contains, for example, file A.xls and A.xls has been changed in source directory then copy A.xls but keep the previous A in destination directory as well. To preserve the previous file a datestamp, or counter can be added to the file name.

Example after copy:
SomeDirectory
|--A.xls
|--A_20120701.xls
|--A_20120920.xls

Thank you.
