Here is a Wikipedia article explaining what it is that needs to be backed up and restored: http://en.wikipedia.org/wiki/Symbolic_link

WaveLab 6 will not do this, and it would be an easy oversight in WaveLab 7 because not many folks bother with or even know about this.

It is important to back these links up for what they are; junctions, links, and aliases, and not the target(s) they point to. Targets must be backed up separately, and likely on purpose by the end user. To back up targets instead of the links results in horrible levels of redundancy, and restores that will not work.

I use junctions in WinXP, Vista Ultimate, and Windows 7 when I create some types of installations. The junctions point back to common data that is kept in ONE place.

Please excuse the software reference below, but it is an example I have in current use:

I have a single USB stick that I can plug into several machines, and have the software run nearly identically even remembering the last project from another machine for a given user.

This isn't set up completely yet, but it does work well enough. I've used computer name and user name in setting up the directory structures, and I use JUNCTIONS to point back to common data.

I cannot find ANY software yet that will not make a mess of a backup and restore because of the NTFS junctions. The backup software either ignores the links (junctions), or will back up the targets instead.

Those are all corrupt backups by definition. Original data is not backed up and restored as it was.

If anyone ever used WaveLab for backup purposes, PLEASE say something here.

Has anyone ever tried to back up their user folders in Vista or Win 7?

I've got news for you.

There are junctions there too, and most backup software simply will not handle the situation correctly.

WaveLab 6 does NOT handle the situation properly either.

If you ever try a restore on such a set of directories regardless of the software you are using, please be careful. Any so called junctions may no longer be junctions and your directories will be partially hosed.

You're brave! I know no-one (even among my fellow system supervisors) who uses Junction Points in Windows, not least because they are unsafe in many operations, certainly up to and including XP.

With Vista and Win7, Microsoft is using these things like never before. They've even created stupid loops with them (junctions referencing a parent directory) which makes improperly written backup software to fail miserably.

They've been around since Windows 2000 I am sure, and I've seen them used in Windows XP about 10 years ago. I didn't use them, but I did see instances of them.

I've now decided to use them too, because they can be so handy.

And I will surely agree that they are not safe in many instances, mostly because of what they are. They are presented to the end user as the TARGET. As such, many operations in Windows simply treat them for the target they represent (which is mostly the point to begin with), and hitting the delete (or other) key will perform said operation on the target as well as on the link. Yep, very dangerous, there is no doubt.

Still, they are now used prolifically in comparison to before, whether we as end users create them or not. I think you still have to be a command line junkie to create them. Yep. Command line junkie....

I want to see WaveLab 7 handle these properly, as well as the aliases in the Mac (if that is the equivalent structure) because these structures ARE becoming more prevalent.

I would still like the backup function in WaveLab 7 to properly back these items up.

I have found that Acronis Backup & Recovery 10 will at least back up and restore junctions properly. I've tested so many backup programs I've lost count.

Still testing some other software.... 2 more to go.

There is a Data CD/DVD facility in WaveLab 7, but that's not a real backup function. It seems you are asking for a feature beyond the scope of WaveLab.
