so...I'm really tired of backing up my PCs (2) & the time it takes, by simply moving important folders to an external hard drive again & again...(or using a backup system, e.g. Paragon, etc.) I like the idea of using Microsoft's backup system (running XP Pro | 2002 | SP3)...in order that...the 1st time I backup it will of course take a long time...but each subsequent time it will only backup new or changed files.
1) What is this method called & how is it accomplished...??? (as explained above, whereby subsequent backups are specific to new or changed files)
2) If I revise a file...ANY file...& do not change the file name (for example...I open 'image1.JPG' in Photoshop...make a few changes to sharpen the image...& save it as the same name; 'image1.JPG')...will MS Backup detect the changes in that file & replace the old image1.JPG w/ the new one...???
i.e., how does MS Backup determine how a file is changed, so it knows to back it up...???
