The ONE thing I wish SONAR did was actually hard save the synth patches. It "remembers" settings but if you have a total system meltdown and for whatever reason (there's many) a reinstalled synth doesn't get recognized as itself, you're hosed. Once you've got all audio you're golden. But synth patches and plugins? Ugh.
 

Check out today's tip.

The best way is to copy the files per xcopy to another drive:
xcopy /s /e /v /c /r /d /y f:\project1 x:\
 
for all Projects:
xcopy /s /e /v /c /r /d /y f:\*.* x:\
 
Make this as a batchfile (*.bat).
We do this since over ten years for over 1000 Projects.

This is from the DOS days for those that don't get it.

What's this "DOS" thing of which you speak? "Dinosaurs of Science"?

Ha, Ha!

What's this "DOS" thing of which you speak? "Dinosaurs of Science"?

It is the Bedrock of MS OSes.

"xcopy" works in all Windows OSes.
A Newer command (Windows 7 and higher) is "robocopy".
It's a command in the shell.
Every admin or poweruser makes use of it.
You can do things with this command you can never do with the explorer.
For example writing a batch-script - and with one click of a desctop icon you can save all projects to an external drive or a network-drive.

Write as a textfile withe the ending ".bat"
 

Acronis TrueImage 2014 suits me fine and I have my own server. Plus all my hard drives are mirrored. And the local vicar comes around every week to exorcise the flat.

I have a Robocopy running daily from one drive to another.  I have a MyDocuments folder (that contains all my VST plugs/synths) on drive F: and all my Projects/audio on drive S:.  My Robocopy copies from S:->F: and also F:->S:.  That way if either drive dies, I have the contents of the other.  It's at the expense of space, but I have plenty of it on both drives.
 
If I were really paranoid, I'd copy off to an external location with a system like Crashplan or whatever. 
 
Speaking of, Crashplan has a free backup application that works for local drives and for a small monthly fee ($10 for the business plan), you can back up a single machine with unlimited files.  In my case, ifI were really worried about having an off-site copy, I'd just run my Robocopies over a VPN to the office server, where Crashplan is running.
 
Here's an example of one of the lines from my scheduled .cmd file:
 

robocopy s:\cake_files f:\audbackup\Cake_Files_Backup *.*  /e /COPY:DAT /r:0 /w:0 /LOG:s:\robocake.log

 
This says to backup all files in the s:\cake_files directory to the f:\audbackup\Cake_Files_Bakup folder, include empty folders, copy all of the security info and such with them, do no read or write retries and write a log file called robocake.log in the root of the s: drive.
 
Robocopy itself is now included in the Windows 8, otherwise, you may need to download it for your version of Windows.
 
Hope this helps someone.
