New backups are saved in this format:
drive letter:\computer name\Backup Set YYYY-MM-DD HHMMSS For example: If your computer name is Brink-PC, your backup location is on hard drive (network or local) F: , and you backed up on July 9th 2011 at 3:10:38 PM (it will use 24 hour time), then your backup would be located at:
F:\BRINK-PC\Backup Set 2011-07-09 151038
There will be a incremental
Backup Files YYYY-MM-DD HHMMSS folder in the
Backup Set... folder location above that contains ZIP folders each under
200MB in size. These ZIP folders contain the selected backed up files. If a file that you included to be backed up is larger 200MB then it will be automatically broken up into several pieces each under 200 MB to fit into multiple ZIP files. The pieces are combined back automatically when
restored from the backup though.
Backups are created in sets known as backup periods.
To help maximize your disk space, Windows Backup backs up all selected folders the first time it's run and then it only backs up files that are new or have been changed since the last scheduled backup was made. Periodically, Windows creates a new, full backup. Each full backup is known as a backup period. When you view your file backups, you see all of the backup periods labeled with date ranges. If you're saving your backups on a hard drive or network location, Windows Backup will create a new, full backup for you automatically when needed. If you're saving your backups on CDs or DVDs and can't find an existing backup disc, or if you want to create a new backup of all of the files on your computer, you can create a full backup.
If you decide to
delete file backups, you should always keep the most recent file backup.
By default, Windows automatically saves as many
system images as it has space for without taking up more than 30 percent of space on the backup disk. Once the disk starts running out of room, Windows deletes older system images. If a system image was created through
Windows Backup instead with the
Include a System Image of Drives box checked (step 9 below), you
can set Windows to retain as many system images as it has space for on the backup disk or to only keep the most recent system image. You should always keep the most recent system image. If you are saving your system image on a network location, you can only keep the most recent system image.
