    Default Can continuous back saving of a DWG compromise the its integrity?

    I heard that continuous backsaving of a file can compromise the file integrity of a drawing. Is this true? If so, is there any documentation out there that supports this and is there something that we can do to minimize or even prevent this from happening? It sounds like it can happen but its the first time that I've heard of the situation.

    Any input would be greatly appreciated. We are currently using 2006 and backsaving to 2000 file format. W/in a matter of days we'll be moving up to 2007 and will have to backsave those to 2000.

    Thanks,
    Christian

    Hi Christian

    Please note I have *moved* this thread from the Software forum to this one, as I believe it will be better served here.

    Thanks, Mike

    I would think that anything that is backsaved consequently tends to compromise the integrity of it. But I don't think it would be so drastic as to loose some sleep over it though.

    Of course, I wouldn't expect that the fuctionality of dyn blocks or any new feature would work when backsaving. I guess i'm more worried about losing data/ content.

    What do you mean by "continuous backsaving " ?
    Continually round-tripping between older and newer versions?
    Saving to an earlier version and keeping it in that version?

    Either way, you shouldn't have a major problem.

    Hi Richard.

    That thread refers to a specific problem and includes the answer -

    I don't think it's the same question, though I'd still ike to know what "continuous backsaving " is supposed to mean.

    I think Christian Is talking about saving down to a previous version of ACAD. setting this permanently in the options area? (let me know if I'm completely off track).

    At a few places I've worked at they have upgraded just one machine and I think every time it has corrupted drawings whilst saving down. Not everytime but often enough to be a problem. My opinion is you either upgrade all the machines in a company or none.

    The link was about a similar problem with 2007 and discussing the use of True Convert by Autodesk which is available free from their website.

    The linked thread actually stated that True Convert would not solve that particular, A2007-specific problem.

    Original Question - Continuous back saving of a DWG can compromise the DWG integrity. Is that true?

    Try True Convert.

    Try the hot fix provided in the link.

    Best to keep a back up that is never saved down.

    Probably me not explaining myself properly.
