PURPOSE


1) Synchronize files and directories, for example between hard drive and USB drive or synchronize two computers via USB drive or LAN

2) General purpose backup and restore utility with many options
 

Synchronization is used to keep updated some directories on several computers you work on. You should synchronize before beginning work on a computer and do it again when you are finished.

Backup is used mostly to create safe copy of your data files. Backup tool is basically a file copy machine with specific options. There are also specialized tools to backup/ clone whole (bootable) drives, specific applications (e-mail), Windows state (registry) etc. Learn more about backup at Wikipedia or by Googling on "backup".

It is useful to think in advance about:
- which backup medium to use (internal or external drive, CD-ROM, networked computer, Internet repository)
- backup directory structure and naming strategy and how often you want to backup your data.
- do you want to have only the latest files or to keep all old versions?
- do you want to make backup copies of all files or only those changed from last backup.

HOW TO USE

Manual or Simple panels are used for one time backup or sync jobs, while Batch panel is used for routine (repetitive) jobs. On Manual panel you may set all the options and then click [Add to Batch] button to add this job to the Batch command list. Batch commands are DOS-like command lines which can be saved in textual script files (*.BAL) for further use. You can have many jobs in a single batch file.

For general backup use, it is good to go to Options and click [Set default backup location] to choose target path, for example D:\BACKUP. Preferred backup location should be on another physical drive in the system or USB attached drive or USB stick. Backup works in incremental mode (only files changed since last backup are updated).
After setting backup location, go to Manual panel and use Update mode to backup files. Use restore mode to copy back previous backup from target to source. Restore will overwrite newer files in the source directory and add missing ones, so you will have file structure like at the moment of last backup.

Action menu: located on top-right corner offers some additional actions:

  • Break operation - stops Preview or Execute operations. Esc key may be used too.
  • Drives properties -lists available disk drives and free space
  • Sleep PC when done - Sleep when Execute or Run is finished
  • Shutdown when done - Shutdown when Execute or Run is finished
  • Save report - if option [x] Make report is enabled, this item can save report to disk
  • Check for Update - check for new Zback version now
  • Go to Homepage - Browse to Zback homepage
  • Advanced (view INI file, make Desktop Icon for Zback, Make non elevated ZbackA.exe, View Debugging Data)

SIMPLE BACKUP

Using Simple backup is like using Manual backup with default settings. Before using it, it is good to [Set default backup location] in Options tab - this way you will not need to set backup location each time. It will Backup or Restore all files including subdirectories (if Include Subdirs option is checked). The option Include Source Path is used to make backups organized by source path, so that backup files are on the same path as source path (for example if Source path is C:\Dev\work, actual backup directory will be D:\Backup\C(#)\Dev\work). Actual target directory is previewed on right side of status bar. In Restore mode first set original Source location. If option Include Source Path is checked you do not have to navigate to actual full Target (backup) path, just leave default (for example d:\backup). Click [Preview] and when to-do list is done, click [Execute] button. You can track progress on progress bar and status bar. Operation can be stopped at any time pressing ESC key or clicking on Break button [X] on top left of To-do list.

SIMPLE SYNCHRO

Using Simple Synchro is used to synchronize directories, for example directories on hard drive with ones on the USB stick. When done, both directories will contain latest versions of all files. It will include subdirectories (if Include Subdirs option is checked). Click [Preview] and when to-do list is done, click [Execute] button.

MANUAL OPERATION

In Manual operation you first set Source and Target directory, for example  c:\work and d:\backup\work. Alternatively, you can drag directory from Windows explorer and drop it to left or right directory list in Zback. If Target directory does not exists yet, you can create it using [MkDir] button.

Then set copy mode:

  • update (backup) - it will copy new files from source to target directory and update to new versions of existing files. This is default mode, it is good for backup files to other disk, external USB drive or a stick. You may also choose to keep old (multiple) versions of backup files.
  • mirror source to target - target directory will be identical as source (it adds new files to target, updates existing, deletes surplus files and directories from target, overwrites target files even if newer then source). Use this mode only if you are sure that target files may be discarded.
  • copy all - copies all source files that pass filters to target directory regardless of which is newer
  • synchronize <> - update bidirectionally (from Source to Target and vice versa). This mode is good for synchronizing home and office computer directories using USB stick.
  • erase source - erases files from source directory, no copy (useful for erasing temporary files)
  • backup [date] - copy source files to unique dated target directory (for example to D:\Backup\[2009-12-15_9-37-31]\). This mode is good for making chronological backups. You can make daily, monthly, etc. backups (see Option Backup [Date] dir. name)
  • restore < - restore (copy different date) files from Target to Source. It is used to restore files from backup location back to Source directory.

When choosing mode, watch status bar for additional info about modes.

You can choose to copy all files/ directories or use several filters and options:

  • Main Filters tab:
    • include only specific file type (for example: *.doc,*.txt,project*.*)
    • exclude specific file types or specific file(s) (for example: *.exe,*.tmp,test.bal,old*.*)
    • include Source path in Target path (good to organize backups)
    • include (all) subdirectories
  • Files tab:
    • include only between file dates
    • include based on file size
    • include only new files (not existing on Target)
    • include only files existing on Target (refresh)
    • keep old file versions when updating files
    • keep old/surplus versions of files/dirs in separate directory  (works with mirror too)
  • Dirs tab:
    • include only given source directories and their subdirs (for example: Work,My Pictures)
    • exclude some source directories and their subdirs (or unique paths)  (for example: Windows,Temp*,\Video\Misc)
    • include only new dirs - not existing on Target
    • existing dirs only - exclude subdirectories that do not exist on Target
    • show hidden/system directories on Manual directory list boxes (needed to see Google drive, etc.)

After making above settings, click on [Preview] to get preview in the to-do list of what files will be copied/ deleted.

When you are satisfied with the list, click [Execute] to start copy files. When busy Zback can be paused/ stopped using [Esc] key.

When comparing source and target files, they are considered to be the same if they have same name and last modified date. But if the file size differs, you will be notified. It is also possible to use "Compare files by content" option to be sure that they are really the same.

Please note that on Windows Vista or higher you need explicit administrator privileges to write files outside "User" folders.

Preview (to-do) list customization

Before clicking [Execute] you can change some lines in to-do list.  On the to-do list you can click on [>>] icons or use right-click for menu of actions. This way you can uncheck lines that you do not want to be executed or you can change copy direction or do other actions. Look at statusbar to see what is the particular meaning of clicked to-do line.
Clicking on [>>] icon in to-do list directory label line (line starting with =[), you can Enable/ Disable/ Reverse all files in the stated directory. Please note that multiple lines may be selected in to-do list (shift key+ click). To-do list context menu offer more functions including list search. For most actions in to-do menu you should select list line(s) first.

BATCH OPERATION

In Batch operation you [Load] batch script file(s) or create a [New] one manually, or using [Add to Batch] button on Manual tab (button offers menu to chose between adding to existing batch or making new batch). You can [Save] batch file in ANSI or Unicode format (recommended to preserve language specific characters). Right-click on batch file list for additional options (schedule repetitive jobs, put PC to Sleep when batch job is done, etc). When batch script is done you have two options to execute it:

  • use [Preview Batch] to generate preview of all operations and then use [Execute Batch], or
  • use [Batch Run] to execute immediately command lines one by one (this is one-click operation but you do not get preview before execute).

In batch operation you can perform complex tasks, for example backup to multiple disks or backup multiple work directories with a single click. Each line in batch file (command script) represent one job (see example.bal file). It specifies source and target paths and mode of operation:


Batch backup line format:

   SourcePath\Mask  > TargetPath  [/mode[options]] 

# This is example batch command script for routine backups (*.bal)
c:\work\*.*  >  d:\backup\work  /us   #(backup current work to D:)
c:\work\*.*  >  f:\work  /ms          #(make mirror on stick F:)
# Backup to LAN computer Coreduo, external drive U:, folder \work
C:\work\*.*  >  \\Coreduo\xporter (u)\work  /us 


Mode:
u= Update (Backup) (= Refresh existing files + add New files, default mode!)
m= Mirror source to target (= Refresh + New + Erase surplus Target files)
c= Copy all files from Source to Target regardless of which is newer
U= Synchronize (=update bidirectional, Source to Target and back) (=b)
b= alternate to U (above)
e= Erase Source files (for example: c:\work\*.tmp > (nul) /es)
   Note: (nul) is required as target
d= Backup - copy files to unique TargetDir\[Date_Time] directory
o= Restore files from Target to Source (copy different date files)

Options:
s= recurse subdirectories too
n= copy only new files (not existing on Target)
r= copy files existing on Target only (refresh)
y= ask before processing batch line
t= filter source files based on file date (t=[dd.mm.yyyy_dd.mm.yyyy])
   (date format must be adjusted for your regional settings) 
z= filter source files based on size (kB) (e.g. z=[11-22])
k= exclude source files with extension(s) (e.g. k=[*.bac,*.tmp])
j= process system + hidden files/dirs too
f= include only given source directories and their subdirs (e.g. f=[Work,My Pictures])
g= exclude some source directories and their subdirs (e.g. g=[Windows,Temp*,\Video])
   ("\Video" excludes absolute/unique "SourcePath\Video" path, see Example.bal Ex.30 and Ex.07)
p= exclude source subdirectories that do not exist on Target (See also Example 33).
q= include only new dirs - not existing on Target
v= when updating keep old versions of target files (old file renamed adding file_Date_Time)
i= keep old/surplus versions of files/dirs in dir @bak@\[Date_Time] (for update/mirror mode)
x= delete source files after copy = move files (e.g. /cx= move files) (caution!)
h= shred source files after copy (e.g. /ch= secure move files, /eh= shred files) (caution !!)
1..6= Date_Time format modifier for mode /d (d1..d6), or options /v (v1..v6) and /i (i1..i6)

Options that have to be entered manually (i.e. not found in Zback interface): 
    Date_Time number 1..6 for options /v and /i, 
    option characters /x, /h, /y.

Special codes to use in batch command lines:
?=k = define ?: drive to be drive k: (may also be ?=|XPORTER| drive name or LAN, see Tip 4)
?:  = prompt user to specify drive if not already defined (? is wildcard for drive character)
%:  = drive where Zback.exe is located
\=  shortcut for Source Dir name:
   c:\beta\toto > d:\back\=
   will do:
   c:\beta\toto > d:\back\toto 
\== shortcut for Source Path:
   c:\beta\toto > d:\back\==
   will do:
   c:\beta\toto > d:\back\beta\toto 
\=== is shortcut for Source Drive + Source Path
%mydocs% = "My Documents" directory, see Tip 9 (example: %mydocs%\*.* > d:\backup\my /us)
%user% = root of current user directories (C:\Documents and Settings\(username))
%progfiles% = "Program files" directory (usually C:\Program files)
%computername% = Computer name, see Example 32
%backup% = Default backup drive+ directory (as set in Options)
<=> = reverse copy direction for whole batch
$searchSt=>replaceSt = replace string for whole batch (e.g. $c:=>d:). Max 2 statements per batch.
$swapSt1<>swapSt2 = swap string for whole batch (bidirectional replace e.g. $dir1<>dir2)
|dname|  = drive specified by its name (for example use |main drive| instead of c:)
#   = comment line 
#'  = comment line will also appear in To-do list and Report
#'? = comment line will ask if you wish to process this segment of list (ending with #'?. line, Ex.31)
##  = stop processing batch list after line starting with ##

Line prefixes in To-do list (first character describing line purpose):
[ = create directory
+ = copy file
* = delete file
$ = delete surplus directory on target
= = directory label line
# = comment line

second character in To-do list means:
- = copy (new file or directory)
  = blank, copy (refresh existing file)
@ = copy (refresh existing file and keep old version)
* = copy (overwrite newer file!)
= = copy (overwrite identical file)
^ = copy (same date but different size)
" = copy (same date but different content)
! = delete (source file)
> = executed copy, erase or make directory (< = reverse copy) 
Batch file menu:

If you right-click on batch file list context menu will open:

  • LIST usage details: lists batch files and info when last used.
  • Set job due Interval: set interval in days when selected job have to be repeated.
  • RUN overdue jobs: run all jobs for which interval has elapsed.
  • Delete batch job file: delete selected batch file from disk.
  • Explore BAL directory: open Explorer on directory where batch files are located.
  • Drives properties: lists disk drives, their capacity, free space and drive type.
  • Sleep PC when done on/off: option to put PC to sleep mode after batch Execute or Run.
  • Settings to Manual on/off: option to transfer settings from last previewed batch line to manual panel.

Scheduled batch execution:

You can set how often batch job have to be executed (interval in days). In this way you may be reminded at Zback start to run jobs that have to be executed.

  • Option "LOG batch use date" should be set to "ON" or "Run all overdue jobs" and then click [Save options].
  • On batch panel, right-click on batch file list (top left) and choose "Set job due interval" for current batch.
    "List usage details" shows all batch files and their due intervals.
  • Choose "Run all overdue jobs" to execute.

Cloud drive:

Zback can be used as a front-end for Google Drive, DropBox or other cloud service.
Put local copy location of Google Disk (for example: "C:\Users\dave\Google disk") as a Target directory of Zback.
For example, use script like: D:\U\HTML\*.zip,*.doc > C:\Users\dave\Google disk\=  /ms  (to mirror DOC and ZIP files from all subfolders).
Later, Google driver will transfer the changes to Google Drive remote cloud location.

COMMAND LINE OPERATION

  • you can start Zback with parameters. Do this using Windows Start menu/ Run or using console window or using BAT file.
  • you can specify batch command line as parameter1 (for example: Zback.exe  "C:\totto\*.* > D:\Backup /us").
  • you can specify BAL file as command line parameter1, and then you can also set parameter2:
    • parameter2 may be:
       
      /l - auto-start [Preview Batch],
       
      /r -auto-start [Batch Run],
       
      /R -minimize Zback, auto-start [Batch Run], then close Zback (quiet run). It is good for making automatic backups using Windows Scheduled tasks. Quiet mode will not prompt user about copy errors (use with caution!).
      /Rs -same as /R, but also save report to Batchname.TXT in the directory where Batchname.BAL is located.
      Example
      : c:\zback\Zback.exe   "c:\work\Batchname.bal"   /Rs
      Remark
      : If path is not specified for batch file, it is assumed to be in default location (usually Zback directory).

PROGRAM OPTIONS

  • Backup [Date] dir. name - sets Date_Time format for mode Backup [Date]. Setting numbers shown here are used by batch command line as /d1.../d6. Default target directory name is [yyyy-mm-dd_hh-nn-ss] (code /d1). In this case directory name is unique because next backup will have different date-time (all the files that pass filters will always be copied because target directory is new and empty).
    If you choose for example daily backup [yyyy-mm-dd] (code /d4) and you make several backups on that day, this same directory will be updated. So this directory will contain last content of source directory on this day. Using this alternative setting you will not have many surplus copies of same files (it saves disk space). So older versions of files will be overwritten in target directory, but if you wish to keep them too, you can use setting [x] Keep old version (Manual/Files tab). Same Date_Time format codes 1...6 may be used in Keep older version option /v (v1...v6) or Keep in new dir /i (i1...i6) but number has to be entered manually in batch line.
  • Compare files by content - if file names, dates and sizes are equal, you will get warning if content is different (this option will make [Preview] much slower!). This is done by comparing CRC32 checksums.
  • List  system+hidden too - those files are invisible if this option not checked. if checked they can be rewritten or deleted (same as /j batch option. use with caution!).
  • Del. non empty dirs-mirror - it should be checked if target should be exact copy of source. (surplus target directories will be removed)
  • Make empty dirs - copy empty directories from source to target too. Grayed state = don't make and don't list.
  • Ignore NTFS Daylight time - you can ignore NTFS 1 hour delay on NTFS drives that might affect file date compare. It is recommended to disable in Windows "[ ] Automatically adjust clock for daylight saving changes" if using NTFS drives. Also, to synchronize computers all of them should be set to same time zone.
  • Skip too long paths - Windows limits path names to 260 characters. Most Windows programs cannot operate with such long paths, including Windows Explorer. You may need special tool to remove/manage such paths, like Total Commander. It is recommended to shorten paths to avoid system errors. If you want to use long paths, option Win native copy method should be checked because it can copy files on long paths (caution!).
     
  • Log batch use date - remember last date when batch job is executed. This information is shown later in Zback caption and you also get it listed at Zback startup. To schedule repetitive backups, use context menu on a batch file list to set due interval in days for some job - this way you will be reminded if you did not do this batch job on time. This control may also be set to Run all overdue batch jobs at Zback startup.
  • Verify copied files - after each file copy verify that copy is identical to the source file (it makes [Execute] somewhat slower).
  • Copy file attributes - target attributes will be same as source, un-check it if you want to remove target read-only, hidden or system attributes.
  • Use recycle bin - if this option is unchecked then files and folders delete are permanent (caution !!).
  • Win native copy method - use this if you have too long pathname files to copy or expect faster copy.
  • Quiet mode - less warnings and question dialogs (use with caution!). Grayed state is max quiet. Quiet mode max may overwrite system and drive root files and change system folders without warning !
  • Set NT Creation dates - set target files Creation dates on Windows NT or higher. This makes copy file virtually same as original.
     
  • Show modes - show all modes (panels) or hide some not needed
  • Specify Drives by name - when clicking [Add to Batch] drives will be specified by its names (for ex:  c:\  -> |main drive|\). Drives must have names ((use Windows Explorer: drive Properties) and be ready. This option may be incompatible with Substitute Special dirs option.
  • Substitute Special dirs - when clicking [Add to Batch] special directories will be substituted by their code (d:\backup to %backup%, etc., see Tip 9).
  • Make Report - after execution you get listing of all operations, on Report tab. Use Right-click on Report (or use arrow button on the left) to save it (ANSI or Unicode) or do other actions.
  • Check for new version - check for new version on homesite when Zback closes (not always but randomly). Click now to check now.
  • Scrollbars in lists - adds horizontal scrollbars in To-do list and Directory tree lists.
     
  • Default Backup location - default target directory name to backup files is \BACKUP. If this option is not set, Zback will propose backup location. You can enter %:\Backup to use (portable) drive where Zback is located. it is also possible to edit Zback.ini file and write BackupDir=%:\Backup.
  • Font - set another font for to-do list, batch commands and report list. Monospaced fonts are recommended (Courier New, Lucida Console, Consolas)
  • Save Options - save all above options to INI file. Some options on Simple and Manual tabs are also saved.
  • More options - click it to show /hide advanced options
  • User's Guide [F1] - (on help panel) opens this file.

TIPS AND TRICKS

  1. Zback.BAL file is automatically loaded at startup, if it exists.
  2. BAL files are normally saved in Zback folder. They may also be located in Zback\MAINTAIN subfolder. Zback Installer version uses "<user>\documents\Zback" folder to store batch and INI files
  3. Direction mark ">" in batch line may be replaced with "<" mark to reverse Source and Target directories.
  4. define drive line ?=k is accepted if drive k: is ready otherwise it is skipped. Subsequent ?= lines will redefine ? drive if this second drive is ready. So you may have one script with multiple ?= lines to do backup on one drive which is currently ready. Define line may have optional parameter: ?=k  / path=[M_latest\new] to define root path (k:\M_latest\new). Command $?=k does the same function but will not redefine drive if already defined.
  5. it is useful to associate BAL files to open with Zback.exe. Then put shortcut to BAL file(s) on the desktop to easy access routine backups.
  6. you can [Load..] multiple batch files at once (they will be appended).
  7. deleted files and directories can be restored from Recycle bin, except from removable drives. Use of Recycle bin can be avoided in options.
  8. note that using Batch Run instead of List + Execute you might get different results because files on disk change as a result of previous batch line(s) execution. Also, progress bar position (job done in %) might not be exact.
  9. using special directory codes %mydocs%, %progfiles% and %backup% enables synchronization between computers with different Windows versions or different user names, without having to adjust/ change batch list (Auto inserted if enabled option [x] Substitute Special dirs).
  10. Simple backup creates one line batch command and executes it. After execution you can click Batch tab and save this command for later use.
  11. to restore default options, delete Zback.ini file and restart Zback.
  12. please note that manual tweaks in to-do list are not reflected in batch command line (if you click [Add to Batch]).
  13. instead of using Restore mode, you may swap left-right directories using [<>] button and then use Copy all or Mirror mode (mirror mode will erase surplus files and directories from the source too). But if there are multiple copies of files in Backup location, they will be copied to Source too.
  14. you can use drag and drop directories from Windows Explorer to Zback on Simple, Manual and Batch tabs (see Known issues for Vista, 7 and up).
  15. some antivirus software can slow down Zback operations when working with many files. Operation speed also depends on  your software and hardware configuration.
  16. if you create INSTALL.INI file (content not important) in Zback directory, it will force Zback to use "my documents\Zback" directory to store batch and INI files (on current machine). This is also good to avoid User Account Control (UAC) on win7.
  17. Zback execution may be restricted by Windows if you do not have permission to overwrite some files (like opened .EXE files, etc). Also some directories are restricted from writing (like Program files). If you have trouble writing or reading network files, test it by using Windows Explorer.

KNOWN ISSUES

  1. Zback runs as elevated (Admin) application in Vista, 7, 8, 10 to be able to access any (system) directory. This inhibits dropping directories from Windows Explorer. But dropping will work if you use any third party file manager (for example Total Commander) and run it as administrator.
  2. For the elevation reason as above, accessing mapped drives in Batch mode may be possible only after the drive is first "activated/opened". For example, activation can be done in Manual tab clicking "choose source directory" button and navigate to desired drive, or using Windows explorer. In elevated Zback, mapped network location might not appear as a drive in Windows 7 and above. Microsoft gives the solution. Alternatively you can map network drive from elevated application or command prompt (net use p:  \\computername\share\test\folder).  Also you can map network drive from Zback itself: go to 'Choose source directory' button, navigate to network location and right-click to map network drive.
  3. You can create a Zback clone (ZbackA.exe) that does not ask for UAC elevation, by using Action menu/Advanced. ZbackA can be elevated manually if needed (Right-click on its icon and choose "Run as Administrator").
  4. batch options/modes /x /h /e delete files as expected, but leave empty directories after operation.
