Synchronize the content of 2 directories

[Apzo]

Hello !

I searched a way to easily backup my au3 scripts from work to home and vice versa.

I found no (simple) equivalent to rsync on windows.

So this is my attempt.

It works "as is" and lets you choose friendly the source and destination directories, or with command line args.

In case of command line mode, remember to enclose spaced paths with "

Example : rsync "c:\documents and settings\me\my_folder" e:\

where e:\ is your USB storage key for example

Rsync checks if a newer version of a file exists on both sides, and copy the newest at the right place.

Rsync doesn't keep an history of your files as SVN would, so in case a file has been modified in the source AND destination, the newest will stay and the older will be overwritten.

I hope this will help

Apzo.

Or you could start a new briefcase. I guess with this you don't have to drag and drop each file.

[Apzo]

No drag and drop needed, just select the 2 folders to synchonize and it's done

Usefull when you work on a project at home and at work : just rsync your project on an USB key.

I'm working on a net version using FTP, so you can allways get the latests files up to date anywhere.

I'm thinking about a file history system, too.

You would be able to set the number of backups for your files, and retrieve up to version-X if needed.

No extra soft to install, just a standalone .exe : AU3 rocks

Hey Apzo, this is awesome. I work on my scripts at home and at work and it has always been a pain to figure out which ones are up to date. I'll start using this! thanks a bunch!

[krigaren]

Very useful script.

Thanks for sharing.

The script is really useful, but one small bug fix in your script would be changing:

If StringRight($PathTo, 1) = "\" Then
    $PathFrom = StringTrimRight($PathTo, 1)
EndIf

[Apzo]

You're right DMEE

I've updated the script.

Thanks !!

Apzo.

There is Microsoft's SyncToy. It works rather well for syncing files.

[kjcdude]

Perfect, just what i was looking for.

'DeltaCopy' is a simple rsync tool for windows. Did you try that ?

[Bart74]

Thanks for this excellent script.

I have modified it to my own needs. I wanted to sync ppt files to a working directory, also the ones that do not exist in the source should be deleted. Also it should not copy any ppt file that is opened for edit.

Works great!

Is it possible to add a progressbar to the script?!

Thanx

[Apzo]

Is it possible to add a progressbar to the script?!

Everything is possible.

BUT the _RSync func is recursive so it's a bit crappy.

At the begenning, add :

Global $FileCount

Global $FileProg

Before the 2 calls to func _RSync() add :

Local $NbFilesFrom = DirGetSize($PathFrom, 1)

Local $NbFilesTo = DirGetSize($PathTo, 1)

If $NbFilesFrom[1] >= $NbFilesTo[1] Then ; Number of processed files = max($NbFilesFrom, $NbFilesTo) * 2, for 2 rsyncs are done

$FileCount = $NbFilesFrom[1] * 2

Else

$FileCount = $NbFilesTo[1] * 2

EndIf

$FileProg = $FileCount

ProgressOn("Rsync", "Synchronizing...") ; Let's go for a progress bar

And just after, ProgressOff() of course.

In the _RSync func, just before the WEnd, add :

ProgressSet($FileProg*100/$FileCount, "Remaining : " & $FileProg)

$FileProg -= 1

And you're done

This works but the status bar goes backwards. It shows a 100% done, then goes down to zero.

I was wondering if there is a way to make this synchonize a local directory with a folder on a server via ftp. But i can't think of any ways to insert the FTP folder correctly. Any suggestions?

[ZacUSNYR]

If you want to use a commmand line utility - check out Robocopy - it came with a Microsoft Resource Kit awhile back but can be found online. It offers a 'mirror' file copy option.

If your interested in Robocopy you coudl check out my Robocopy function. it makes life a lot easier.

Another way to sync dirs is to use a GNU port for windows of the well-known unix command 'cp'.

Check the -u option :

cp --help

...

-u, --update

copy only when the SOURCE file is newer than the destination file or when the destination file is missing

I use it twice : source -> destination then destination -> source.
