Here's how to backup and restore your Wolfram Cloud Folders:

The backup procedure is easy because CloudObjects and Data can be copied to your local disk via CopyDirectory.

(*set new backup folder*)
directorytobackupto = "160204 full backup"

(* set local destination root for backups *)
SetDirectory["E:\\CLOUD BACKUPS\\BAC-PREP\\"]

(* list of folder for backup *)
cloudfolderstocopy = {"/BAC", "/Base/ApplicationData", "/Base/Applications"}

(* change cloud path to local path *)
localfolderstostore =  StringReplace[#, "/" -> "\\"] & /@ cloudfolderstocopy

(*Copy all folders to local disk *)
MapThread[
 (CopyDirectory[
    CloudObject[#1], directorytobackupto <> #2]; 
   Print[ #1 <> " finished"  ]) &,
 {cloudfolderstocopy, localfolderstostore}
 ]

The restore procedure is different for CloudObjects and other files. The CloudObjects on your local disk need to be re-CloudDeployed to be recognized/seen by the Wolfram Cloud server. Note the use of ExternalBundle as a BULK CloudDeploy. Restoring the data files is done by a CopyFile.

restore for cloudobjects:

(*set location to be restored folder *)
SetDirectory["E:\\BAC\\BACdir\\BACdir\\FORMS"];

(*read files, directories and all subdirs *)
myfilenames = FileNames["*", {""}, Infinity];

(* remove paths pointing to folder (and not to a file) *)
onlyfilenames = DeleteCases[myfilenames, x_?DirectoryQ];

(* replace local path escaped backslash by a foreward web slash *)
cloudfilenames = StringReplace[#, "\\" -> "/"] & /@ onlyfilenames;

(* target web folder taken as root *)
cloudappfolder = "/BAC/FORMS/";

(* External Bundle can be used in the current Wolfram Cloud to BULK CloudDeploy *)
b = ExternalBundle[cloudappfolder <> # -> Get[#] & /@ cloudfilenames];

(* if you prefer a 1 by 1 CloudDeploy use line below *)
Map[CloudDeploy[#1[[2]], #1[[1]]] &, b[[1]] ] 

restore for data

(* does not need a re-CloudDeploy, just a CopyFile*)

(* set restore local folder *)
SetDirectory["E:\\BAC\\BACdir\\BACdir\\DATA"];

(* read file names in this dir only *)
myfilenames = FileNames[]
(* copy files one by one to target cloud path *)
CopyFile[#, CloudObject["/BAC/DATA/" <> ToString[#]]] & /@ myfilenames;

Backup and restore keeps your code and data safe but the CloudObjects are not very readable. For obvious reasons the source code is also backup-ed.
