Backup and then restore to defrag?

All,

Hello. I have ATIH 2012. I am curious if this is possible. Fully backup a machine, and then restore (either same disk or different disk). All files are now defragged, correct?

Now, backup will NOT be sector-by-sector, so I assume it's file-by-file.

Based on my thinking and assumptions, if a restore just writes the files to a disk (excluding position dependent files such as those in the MBR), then all files restored will written in contiguous sectors, correct?

On a different note, how does ATIH determine if a file is to be backed up for inc. and diff. backup methods? By NTFS File Archive Attribute? Changed date/time stamp? Or something lower-level such as sector changes? I ask because I came across a another discussion about how someone's defrag caused a major file size increase in his subsequent backups; many mentioned sector changes as the explaination.

This thread is really an opener to a more detailed discussion to what I had in mind for ATIH, and building/rebuilding my machines. When I have more time I will create that posting....

Sincerely,

ATIHNewb
