Alan2273 Posted October 25, 2005 Report Share Posted October 25, 2005 I do not know whether this is a problem or not.I use diskeeper to defragment my hard drives, the two SATA drives are done by set it and forget it and if I do them manually they generally only take a minute to do.My other drive a USB 2 160gb external drive takes about the same time untill I make a back up copy with Acronis true image then it can take up to two hours to defragment.Has anyone else had this problem, does true image splatter the back up all over the drive?.

dagwoood Posted October 25, 2005 Report Share Posted October 25, 2005 Alan2273, it doesn't splatter the files all over the drive, but as backup image files are so large, if the file has fragmented just once, then the Diskeeper has to move files about in GB chunks to arrange the files so they are contiguous. That's what's taking the time.HTH, dagwoood. Quote Link to comment Share on other sites More sharing options...
Alan2273 Posted October 25, 2005 Author Report Share Posted October 25, 2005 Thanks for that answer dagwood, perhaps splatter was not the right word to use. :teehee: Quote Link to comment Share on other sites More sharing options...
dagwoood Posted October 25, 2005 Report Share Posted October 25, 2005 Thanks for that answer dagwood, perhaps splatter was not the right word to use. :teehee:No, I think splatter was a good choice of word. I understood what you meant, so that's good use of English in my books.As an aside, I keep my drive image files on my second hard drive. By mistake I once defragged the drive and it took ages. I then started to wander whether by defragging the image files they were corrupted in any way. So I opened True Image and verified that all my image files were o.k. Needless to say, I don't defrag it now. Quote Link to comment Share on other sites More sharing options...
trackrat Posted October 25, 2005 Report Share Posted October 25, 2005 dagwood are you saying that you do not defrag your drive now because it corrupted the Image?. Quote Link to comment Share on other sites More sharing options...
-pops- Posted October 25, 2005 Report Share Posted October 25, 2005 Take care defragging backups. I have read somewhere that you should leave backups alone as when you require to use them, the limited boot software such as that provided by Acronis or DriveImage looks for the image as it was supposed to be created, not for an image that has been "organised" by a defragmentation system.I did a test once and defragged a DriveImage backup. It would not then do as it was supposed to and the whole thing failed. If that had been a real requirement for a backup I would have been right in the faeces.

trackrat Posted October 25, 2005 Report Share Posted October 25, 2005 Cheers pops, I have used Drive image for about a year now and fortunately have never had to use it to replace anything.I read this thread with interest because i have an external drive which i back up to and i used to defrag it, but after your advice i shall not do it any more.It was a good job i did not have to use the restore ability or i would have ended up in the faeces as well.

CurlyWhirly Posted October 25, 2005 Report Share Posted October 25, 2005 I also use DriveImage 7 as well and I never defrag the backup image as it only takes between 15 and 20 minutes to restore. After reading some comments in this topic I am glad that I didn't defrag as it seems to corrupt it :o Quote Link to comment Share on other sites More sharing options...
ɹəuəllıʍ ʇɐb Posted October 26, 2005 Report Share Posted October 26, 2005 I defrag all my drives, including backup drive (by PowerQuest DataKeeper), nighly, using Diskeeper 9. I don't care now long it takes, as I am not sitting by it and watching it. Quote Link to comment Share on other sites More sharing options...
dagwoood Posted October 26, 2005 Report Share Posted October 26, 2005 dagwood are you saying that you do not defrag your drive now because it corrupted the Image?.Sorry, I didn't make myself clear on that point :blush:Fortunately it didn't corrupt the images, but I'd intentionaly not defragged the drive as I didn't know what the ramifications of defragging an image file could be. I spent some time worrying while the verifications ran, hoping that the image files weren't corrupted. I just don't want to go through that experience again, that's why I don't defrag the drive with my image files on.After reading -pops- warning, it seems my doubts were well founded.

andsome Posted October 26, 2005 Report Share Posted October 26, 2005 I find that with diskeeper a boot time defrag now and again works wonders in the speed things up stakes. Quote Link to comment Share on other sites More sharing options...

-pops- Posted October 27, 2005 Report Share Posted October 27, 2005 Of course, if you're using Acronis Secure Zone (which you should be with that software) then that is hidden from the other parts of the machine and should be safe from attempts to defrag it.I'm not familiar with other backup/image systems now so, if they have hidden partitions they should be safe also - it was a while ago when I did that test, when DriveImage had to come out of Windows in order to do its stuff.

trackrat Posted October 27, 2005 Report Share Posted October 27, 2005 I have just checked the Acronis image after it had been defragged and it said it was OK.But after what you said pops i will do a new image and not defrag the external drive any more. Better safe than sorry. Quote Link to comment Share on other sites More sharing options...
