MyBackup.tib file shown as fragmented, why?
In Windows Disk Defragmenter, ( Acronis 22.214.171.12496 ) tib file is shown as red, fragmented files.
I defragmented that disk partition before making system backup from C partition.
C partition also Defragmented before making system backup.
Is it safe to use Windows Disk Defragmenter in disk partition where tib file is?
They can be defragmented. Acronis .tib files are just files although they are often much larger than files normally encountered.
I wouldn't bother defragging the tib files because they are often rarely, if ever, accessed unlike some Windows files that are accessed very frequently. There is little point in saving a possible few seconds of access time when doing an operation that typically takes several minutes at least.
Any operation that requires reading and re-writing disk information can have a failure in the process. If even 1 bit of a tib file is mis-handled the archive will be declared corrupt by TI.
It isn't worth the risk or the bother IMO.
