set up automatic move of files placed by users in a folder where they
have rights to be transferred by Idem into target network protected
automates file synchronization and data replication
. It secures critical data, copy folders from a computer location to
another or between network drives. This solution for the mirroring of
important folders from a Windows NT/W2K server toward another, checks a
list of source folders at regular time interval and updates target
folders with new or modified files including sub-directories.
Idem BackUp Solution supports and keep Macintosh
filenames and structures stored on a Windows NT/2000 server.
You can use it to
create a mirror
for disaster recovery, to backup files or replication files security.
Use Idem to synchronize a laptop on a network ,
for synchronization of XP folders and for real-time mirroring of
folders on ZIP drive, CD-RW, removable hard disk, network drives, local

Main Features :
definitions of source and target folders keeping files synchronized
between a desktop & laptop or between multiple drives on you
desktop when cloning folders.
Supports UNC (Universal Naming Convention) to name folders using paths
Option to include
sub-folders in mirroring.
Fully preserves Macintosh
filenames and structures stored on a Windows NT 4.0 / 2000 server
running MacFile/SFM (Services For Macintosh) or a MacFile/SFM
compatible server as
Macintosh files are stored with peculiar data structure ("data fork",
"resource fork", "Finder informations") and their names can include
forbidden Windows characters (like \, /, <, >, etc.).
Idem can manage these peculiarities.
Note : Requires Windows NT 4.0 - running MacFile/SFM or
compatible - on NTFS partitions ; this feature is not
implemented on Windows 95/98.
File Handler (Swat Consulting Inc.) in order to mirror opened
files on Windows NT/2000.
- WebDrive (RiverFront). In association with WebDrive, Idem
allows to replicate files using FTP protocol (in order to update mirror
Web sites for example).
can check and copy the files and folders security information
(ACL permissions - access-control lists on NTFS partitions) and the
files and folders attributes (hidden,
system, archive, etc.). This is an interesring feature for network
adminsitrators to replicate data with its security.
Each synchronization can run using one of the following modes:
- update if the file is different
in the source and target folders
- update if the file in the source
folder is newer than the corresponding file in the target
folder. This possibility is used for dual way mirroring.
Setting time interval for update. Each folder can be mirrored using its
specific interval for update.
to remove old files and subfolders from target folders.Runs on
Windows 95/98/ME, NT 4.0 , Windows XP and Windows 2000/2003.
Option to move files from a source folder toward a target folder, i.e.
delete files from source folder after mirroring.
Option to rename moved Macintosh files,
substituting a dash to the forbidden Windows characters in their names
(/, \, <, >, etc.). Moreover, the 3 characters extension
is added for the most commonly used applications: .doc, .qxd, .xls,
etc. For example, a document XPress named Advert 08/12/99 is moved as
All Windows programs can manage these files after renaming. This option
is useful for programs like Adobe Distiller used in Windows environment
on Macintosh files.
Archive mirroring operations in Log files.
When a folder becomes unknown (folder removed or renamed,
lack a connexion with a file server, etc.), Idem can send different
kind of warnings: beep, display message, send a message to an
administrator, messages in the Log, messages in the Applications
EventLog (when Idem is running as a Windows NT service).
will also run as a Windows NT/2000/XP Service.
Screen Shot :
Using Idem to secure Macintosh files stored on a Windows NT
server has other advantages:
- avoid a Macintosh
replication task which is often running on a dedicated Mac.
- reduce network overhead.
- increase speed of mirroring.
- automatic start-up at server boot.
Synchronize a laptop: the command line flag -u
When you run the program
with the command line flag -u [for unknown], Idem stops if any defined
folder is unknown. This is useful when you are using Idem to
synchronize a laptop on a network since Idem is only loaded and running
when the laptop is connected to the network.

target folders using Windows Explorer. Idem uses existing source and
Idem uses logical drives (letters C:, D:, E:, etc.) or
UNC (Universal Naming Convention) names as
- for secure a folder C:\My Data on Server 1 toward a folder D:\My Data
on Server 2, Server 2 must be connected to Server 1 using D: as a drive
- secure a folder \\Server1\Share\My data on \\Server2\Share\My data.
Choose language using the Language menu (French,
If you want to mirror two equivalent folders structures on two
different servers, define the Default drive/UNC prefix for target
folders in the Configuration menu. Examples:
- if D: is the default drive for target folders, adding C:\My Data as a
source folder will add automatically D:\My Data as the corresponding
- if \\Server2\Share is the default UNC prefix for target folders,
adding \\Server1\Share\My data as a source folder will add
automatically \\Server2\Share\My data as the corresponding target
Define the list of source folders using
the Add button down left.
The corresponding target folder is automatically defined if you have
set the default drive or UNC prefix for target folders (cf. supra).
Invalid folder names are preceded by three interrogation marks.
Macintosh folders are preceded by a Mac icon.
each folder you can click on the small clock named set in order to :
- define the time between two mirroring operations for
the given folder using a multiple of the default time. The default time
is set in the menu Configuration/Set default time between two mirroring
operations. For example, if the default time is 10 seconds, you can set
the time between two mirrorings of the considered folder to 10, 20, 30,
- move file from the source folder toward the
target folder. Files are deleted from the source folder after each
- rename moved Macintosh files substituting a dash
to the characters /, \, <, >, etc. in their names.
- delete old files in the target folders: the files
in the target folder which have not corresponding source files are
one of the following update modes:
1. update if the file is different in the source and target folders
2. update if the file in the source folder is newer than the
corresponding file in the target folder
To modify a folder name, select it and click on the Modify
button (source or target), or double-click on the folder name.
To remove couples of folders (source and target) from the mirroring
list, select them and click on the Remove button.
To start mirroring, click on the central
button with arrow or choose the File/Start mirroring menu.
To stop mirroring, click on the same central
button (Stop) or choose the File/Stop mirroring menu.
