Synchronize Files and Synchronize Folders with the Open Source Tool FreeFileSync
Now there are a lot of synchronization tools out there both paid and free, each with a different set of features and marketing spiel. What makes FreeFileSync stand out? It’s user-friendliness and performance. Both are buzz words already used so often that they almost lost their meaning. But still they describe best where FreeFileSync shines: Its user interfaces are stripped off from superfluous and needless options. Many similar tools seem to add every bell and whistle in a futile attempt to please each and every user, failing to realize they serve nobody in the end. FreeFileSync carefully selects only options that are relevant for backup and synchronization, while making tons of smart decisions under the hood. Most of these the user does not even notice unless he reads the long list of features that this tool supports.
Performance on the other hand is easily measurable. I have yet to find a tool which is faster than FreeFileSync, but there are a few tools specialized at high-performance file copying which seem equally fast. Using system logging tools like Process Monitor it becomes clear why: There is not a single superfluous file access during synchronization. There’s exactly one read access for each file during comparison and another one when synchronizing a file or folder. For a tool which is primarily I/O bound this is as good as it can get, but can rarely be expected when looking at other synchronization alternatives – no matter if free or commercial.
Besides these obvious features, there are more subtle characteristics that are easily overlooked. The FreeFileSync bug tracker has been empty or almost empty for years. This is not to say there were no bugs, but each of them was solved almost instantly within hours or a few days. This is quite remarkable for an open source software in general, and it does not even charge support fees. The release cycles have been around once per month for the past few years. This speaks for a modern agile software development process. Lastly with now five years of development it can be considered a mature and stable solution.
The first thing that you see when you start up FreeFileSync is a very well-arranged and structured user interface. It does not require much reading of documentation to figure out how to setup a synchronization task. You choose directories for left and right side, then compare them. This will fill the preview panel telling exactly what is going to happen before even touching your precious data. Now you can change the sync direction for individual files or select one of a number of synchronization variants. These are pre-configured rules that describe how you want your files and folders to be synchronized. The “mirror variant” for example will synchronize files and synchronize folders from left to right, making sure the target side is updated to reflect the source. Or you may want to select the “two way” variant where both sides are taken into consideration: Any change on one side is propagated to the other. If you have deleted a file, changed a file’s content or created a new file, this change will be synchronized to the other side, even if changes on both sides have occurred since last synchronization. Thereby the program is smart enough to detect conflicts, i.e. if you accidentally changed the same file on both sides, the program will warn and request a manual resolution. So the tool makes sure you do not lose important data, even if you make stupid mistakes.
FreeFileSync can be downloaded for free. Here is a list of the most important features taken from the project site:
– Detect moved and renamed files and folders
– Copy locked files (Volume Shadow Copy Service)
– Detect conflicts and propagate deletions
– Binary file comparison
– Full support for Symbolic Links
– Automate sync as a batch job
– Process multiple folder pairs
– Comprehensive and detailed error reporting
– Copy NTFS extended attributes (compressed, encrypted, sparse)
– Copy NTFS security permissions
– Support long path names greater than 260 characters
– Fail-safe file copy
– Cross-platform: Windows/Linux
– Expand environment variables like %USERPROFILE%
– Access variable drive letters by volume name (USB sticks)
– Native 64-bit support
– Keep versions of deleted/updated files
– Optimal sync sequence prevents disc space bottlenecks
– Full Unicode support
– Highly optimized performance
– Include/exclude files via filter
– Local and portable installation
– Handle daylight saving time changes on FAT/FAT32
– Use macros %time%, %date%, et al. for recurring backups
– Case sensitive synchronization
– Built-in locking serializes multiple jobs running against the same network share

Top Reasons that Data is Gone from Your iPhone and How to Get Lost Data back
While losing data affects everyone who uses an iPhone, especially for those who reply on iPhone for business. It is really an unpleasant experience. And while retrieving the erased data can be extremely difficult to deal with in some cases, preventing against data loss is very important to you.
The reason that data goes missing are varied, but seven listed below are the most common.
1. iOS software update
Some users state that their contacts were wiped when updating to the new iOS, even after restoring the rest of the device’s settings as is the norm. Its recommended that you just hit “update” button left without any security of your content, all you have to remember is to back up your device to either iCloud or iTunes on a local computer.
2. Restore to factory settings
Restoring your iPhone to factory settings may remove all of your personal information like text messages, notes and appointments, although it retains some of its apps.
3. Jailbreak
Jailbreaking your iPhone voids the warranty, and this operation often got stuck in DFU mode. Restoring your iPhone in iTunes will erase everything including SMS, photos, videos etc.
4. Delete data due to mis-operation
Deleting information simply by touching the screen the wrong way, getting rid of unwanted contacts on your iPhone or other mis-operations will make your regret most before backup.
5. iPhone crashing
iPhone crashing like camera library, mail or contact app crashing will put your iPhone into blank screen with Apple sign in white. Then you find all your photos, contacts were gone after it came back.
6. Get your iPhone wet or have it stolen
If you have had the horrible misfortune of having your iPhone dropped in water or stolen, maybe you will see all your valuable information get lost, including contacts, photos, music, SMS, ideas, etc. in a second.
7. Replacing iPhone battery
All flash memory in the phone (except RAM) is retained without power. Replacing the battery has the same effect as resetting your iPhone, be careful with this!
We didnt realize the seriousness of the situations such as the above until we deleted a crucial message on iPhone. But are the deleted files deleted permanently? Users should be aware that highly sensitive data can still be retrieved from either iTunes backup file or iPhone directly some of the time. Below are the steps from recovering lost data via two means.
Restoring from a previous iTunes backup
You’re in luck if you have backed up before you deleted the contacts, just restore from iTunes backup files via iTunes.
Note: Back up your iPhone using iTunes prior to following these instructions. During the following instructions you’ll be advised to erase all data from your iPhone. If you do not back up the data that resides only on your iPhone, such as pictures or notes, that data will be permanently lost.
Step 1: Configure iTunes so that it doesn’t automatically sync with your iPhone when it is connected to your computer;
Step 2: Connect your iPhone to your computer;
Step 3: Open iTunes, right-click on your device and press “Restore from backup…”.
Recovery tool method to retrieve deleted files without backup
Due to the special technology of iPhone, it’s very hard to recover data directly from the iPhone itself, but it’s not impossible. Professional programs such as Fone Rescue, the iPhone data recovery utility (with separate versions for Windows and Mac) can help to retrieve deleted files without backup, it works with all iOS devices including newer iPads, the iPhone 5, and the iPhone 4S etc. Fone Rescue isn’t perfect, but if you’ve accidentally deleted an important photo or file, you know that some things are priceless.
