    Hi, did anyone succeed in making backups of share on a XP-computer. I keep getting the error: INVALID JOB PATH. I think i used the wrong format when defining a backup job. Can anyone give me an example.

    This is the information i need to fill in:

    This NSLU2:
    Share: ______________

    Other device:
    Shared folder:_____________

    What do I have to fill in if I want to backup this folder: "\\Antec\Kees" which resides on my XP computer

    to the folder "\\Fileserver\ADMIN 1\kees\Backups" which is on my NSLU2

    (Fileserver is the name I gave to the NSLU2 and that's how it is presented in my XP-network environment)

    For all the non-NSLU2 owners: this is a neat piece of hardware that will make my life a lot easier (it already has!).

    I already know what the problem was: the correct of the slashes /or \. It should be these: /

    But now I've got another problem:

    If I share for example: c:/test and try to automatically backup this folder to the NSLU2, it goes perfect. Also I share c:/test/test then it also goes perfect.

    But when I try to automatically backup this folder: "C:\Documents and Settings\kees" it doesn't work. The NSLU2 doesn't give an answer in the logfile. It just says 11/15 13:11:21 Backup: Job 'Kees_pers' started. and that's it.

    Has anybody succeeded in backuping it's Documents and settingsfolder?

    I don't have an NSLU2 but I can tell you that user folders under C:\Documents and Settings are often protected with permissions that only allow that user read the folder, you might need to change the permission on that folder before it will backup.

    That is incorrect: backup tools do not suffer from this problem: they just backup the data, but only someone with the right permissions can actually do something with the data.

    If a backup tools would suffer from these problems, no backups could be made at all..

    Backing up a database is another story: then info (transactions) need to be locked etc..

    Not really a solution... but I am always making backups manually using a batch file with xcopy...

    works fine so far

    Well, as long as you backup data only this will work. But making a backup from your whole system is another task! Files that are "in use" like the swap file, registry, some DLL's etc, want be copied.

    Backup tools like Acronis True Image and Norton have special ways to circumvent this.

    So yeah: xcopy (or any orther copy) will work on data like My Documents etc.. but not for backing up a whole system.

    For backing up my system partition I use Norton Ghost, but I don't know if you can create and more important restore an image from the nslu2...

    Have no idea what the problem was. All problems are solved. The NSLU2 currently makes automatic backups over the network from my whole Documents and Settings folder. (great, safe feeling)

    Yes, you can do this but there are some pitfalls:

    1. Ghost backs up from DOS so you need a bootfloppy with network access. You can make this using Ghost in Windows (make sure you have the correct driver for your network card). I actually never made that work (though I might be able to now, knowing what I've learned since). I used a Bart's Network Bootdisk in the end, see:


    2. You have to make sure that you set "Plug-and-Play OS" to "No" in your bios.

    3. You have to create a drive-mapping to the NSLU2 and you have to put a copy of the Ghost executable on the NSLU2 AND RUN IT FROM THERE

    There is a problem in this that I (so far) haven't been able to get around:

    - if I do a DIR on the NSLU2-mapped drive, I get an error and no listing. This is reflected in Ghost being unable to populate it's directory window with the files on the mapped drive.

    I can copy files in both directions from the command line and Ghost will actually perform a backup/restore but you have to know the valid filename in each case because you can't see the files. So it can be done but it's not very clean.

    This seems to be a conflict between the NSLU2 firmware and the DOS software. I've left a post here and at other places to see if anyone can suggest a solution to this. I hope there is a solution because the NSLU2/Ghost combination seems an ideal combination for backing up several machines on a small network.

    Incidentally, I did try installing unslung 2.x but it didn't help this problem.

    If you do try this, I'd be very interested to learn if you have the same problem.

    Actually I heard that the latest and greatest version of Ghost no longer exits to DOS. From what I understand it will also do automatic backups or both linux and the other operating system, it does incremental backups and so on.

    Is that Version 9? Sounds interesting. Might give it a try.

    There have been other programs that purported to backup Windows from within Windows with varying degrees of success (Roxio had one that they dropped after a bit). The obvious problem of course is that, while Windows is running, certain files are locked and therefore inaccessible. Which is the reason for doing this kind of thing from DOS in the first place.

    The sheer crudity of the Ghost DOS interface programming doesn't give much confidence in the programmers' ability to succesfully implement a decent all-windows solution.
