Large Acronis file in Defrag analysis

Thread needs solution

Hello, I have had Acronis 10 for over two years and it has done my back-ups faultlessly. I have done a Defrag of the Hard Disc twice over these last two weeks and I have a large amount of Files that cannot be Fragmented (ie. the red block in XP) for some reason. I have established in the Analysis option Acronis Back Up has a 44 GB file in it that cannot be Defragmented. The Hard Disc is 298 GB in size and the Free Space is 153GB. I have never had this before and I guess it cannot be correct. Can anyone advise me please what to do ?

I assume you're using the built-in defragger in XP and therefore this red-block file is a backup file, a .tib file?

In any event, defragging monterously large files is not likely to bring you anything noticable accept early hdisk failure. Suppose even that the file is in, say, a thousand fragments. If you defrag it, and some day do actually use it once to restore (most backupsnever get used at all), then in exchange for a few milliseconds of disk access time while perofrming a restore process that's going to take oodles of time anyway, you have been thrashing your harddisk for hours on end with a defragger.

I recommend not defragging those big big really big files.

Btw, I can't imagine any file in the ATI program that would be even a tenth that size, and a backup is not likely to be that large unless you're backing up over 44GB of data in one backup. So it could be a normal file, depending on what you've been backing up, or maybe it is several backup files? In either case, I would not defrag tib files, there's just no percentage in it.
