Does built in Windows 7 backup perform differential (incremental) backups?

Hi,

I use Windows 7 Backup for simple home backup. Windows 7 backup seems to maintain about 3 versions of the backup, for the last three days. I only ever want the lastest set of files to be backed up - is that an incremental? I basically only want it to backup those files that have changed.

I know that its better practice to have multiple versions of the backup, however I swap out external hard drives every couple of days, so I do always have a couple of versions.

Thanks Al

It might be worth reading about backups. This article from Acronis provides information about Full, Differential and Incremental Backups.
http://www.acronis.com/resource/solutions/backup/2005/incremental-backups.html

It sounds like you want to be doing differential backups. One full backup and then differentials every so often only storing the latest one.

  • What Acronis products offer and what Windows 7 offer are completely different. You get the choice with Acronis, but you don't with Windows 7 - for further details, see the link in my comment to the OP. – CJM Nov 10 '10 at 12:18
  • The article was meant only to allow the user to understand the difference between differential and incremental backups. But the answer to the other question is quite interesting. – Joe Taylor Nov 10 '10 at 17:24
