SynchroDir 1.7

64 bits pour Mac Intel

This version of SynchroDir has been specially compiled for Intel Mac until Mountain Lion 10.8 and is running in 64-bit mode. It is a little less bulky and a bit faster than the universal version.


SynchroDir backup utility is trilingual English / French / Czech with a single click on the menu « language ».

Each backup is the subject of a recordable « backup project ». This feature allows you to save projects corresponding to different computers, servers, external hard drives, USB keys, etc.. You can also backup data of computer Y to computer Z from a control computer X.

Each backup project includes an unlimited number of "jobs". At the end of the backup process, a log file is available.

Each job has a source (What?) and a destination (Where ?), each corresponding to a volume or a directory. The volume or directory must be "mounted". The mounting features of Unix, including Mac OS X, allow you to make backups over the network through the Mac OS X protocols (AFP, SMB)

Each job has an "Options" tab and a "Filters" tab allowing many settings. It possible to perform each job in test mode: the backup is not performed but the log file is saved, allowing to know what would have been done in normal mode.

The SynchroDir backup utility is provided without help. Each new job is created with default options that are appropriate for most of uses. On mouse over, numerous tool tips are available.

Job types

For each of the jobs of a project, you must select the type of backup in a combo box:

Miror: copy or update to the source (What) in the destination (Where) modulo filters.
Synchro: update the source (What) and update the destination (Where) according to the date of last modification.
clean: clean the contents of the destination (Where) accordind to exclusion filters.
Move: move the contents of the source (What) to the destination (Where) based on exclusion filters. Then, the entire contents of the source (What) is cleared.


The utility does not process jobs with unmounted directories or volumes.

In the case of a backup mirror:
If the source (What) is: /Users/jean-pierre/Documents/Images
and destination (where) is: /Volumes / Documents
The contents of the /images directory will replace the entire contents of the directory /Volumes/Documents.

It is therefore very important to check that the job is initialized as follows:
Source (What): /Users/jean-pierre/Documents/Images
and destination (where): /Volumes/Documents/Images
In this case, everything works perfectly. Why not do first a test since it's possible : just partially check the Y/N box of a job. An "as is" log of the backup will be performed ...
