The Basics
The basic idea behind Allway Sync is pretty simple. You start off with two folders you want to have at the same state. This can be two folders on the same computer, on two different computers or one folder on a computer and one on a server.
Before synchronizing you can have the program present you with a pane showing differences between the two folders. There you can change synchronization settings (like the direction) for files individually, or mark files for the software to skip when synchronizing. Once you are done you simply hit ‘Synchronize’ and Allway Sync will do the rest.
Scheduling
One thing Allway Sync really shines at is scheduling. You get more options than you are ever likely to use. You can have your data synchronized periodically or manually or a mixture of both, for instance.
File Versioning
Now this is something I really love about this tool. Instead of only deleting older version of files, you can tell the program what to do with those outdated versions. You can, for instance, have older versions be saved into an archive folder. In my opinion this feature can be a real life saver.
Verdict
Allway Sync is very fast and very easy to deal with. While being simple in its basic use, there is more options than you will most likely ever shake your stick at. If you use a tool that synchronizes your data automatically and securely between different locations, if you expect the tool to be easy to use while giving you the option to set up special rules for certain items; then this is definitely for you.

When it comes to synchronization of data between two or more computers, the very first question you have to ask yourself is: what data do I really need synchronized? This is particulary important if one of your computers is a laptop with limited space on the hard drive.

Types of Data
There is a whole range of data on a computer. To make the decision what data to synchronize easier it helps tremendously to categorize the data. There are basically following types of data: e-mail, calendar items, contact data, documents, media (images, movies, music). Thinking about your data in terms of those categories will let you decide on what data to actually synchronize more easily

What to Synchronize – and what not
Finding out what data to actually synchronize is not really all that hard, all you really need to find out is a bit of common sense.
First rule: do not synchronize everything. In other words, you should not abuse synchronization for backup purposes. There are masses of data on your computer that you do not really need on every computer you use.
Second rule: ask yourself what you are actually working on when working on a secondary computer. Most probably you bought a second computer for a specific purpose. Keep this purpose in mind and synchronize accordingly. For instance, if you bought a laptop to be able to check mail on the go and continue working on your text documents, you should really only synchronize those two sets of data.

If you own more computers and manage your life using a calendar application like Microsoft Outlook, you definitely want to make sure the calendar on your machines are at the same state whenever you use them. Unfortunately, this task can be quite cumbersome and you very often risk losing calendar data. There are, however, a few tools and tricks that can help achieving the task with a minimal amount of headache.

The Manual Way
You could, of course, manually synchronize the Outlook Calendar between two computers. In other words, you’d copy the Outlook data file back and forth between your computers. Where does Outlook store its data though?
Outlook stores all your data in Personal Folder Files (which have the extension .pst). Finding this .pst file is no rocket science, yet you have to know where to look: Open Outlook and Select ‘File > Data File Management’. You will be presented with a dialog that has several tabs, with the tab ‘Data Files’ active. There highlight your main data file (typically named ‘Personal Folders’. Click ‘Open Folder …’. The file explorer will open with your .pst file highlighted.

The Automatic Way
There needs to be an easier way though, don’t you think? Of course there is. Actually, there are quite a few tools out there, which can help you tremendously getting this job done. While I can’t say, that I used them all, I so far found PSTSync the absolutely best tool I tried so far.
This tool will help you synchronize Emails, Contacts, Tasks, Notes AND – of course – your calendar between two computers. But it doesn’t stop there. It also allows your to synchronize your calendar data with other people, helps you exporting your Outlook data files (including online locations), protect your Outlook data with a secure password protection … and other things.

You have a two computers (a desktop and a laptop for instance) and use both of them. Naturally, you will create data on both machines, be it documents, e-mails, spreadsheets, images. Sooner or later (most probably sooner) you will want to make sure that both computers have the same data.
