How does computer backup work?
Updated: March 30, 2011
Applies To: Windows Home Server 2011
The following things happen during the backup each day:
Home computers are backed up one after another.
A backup that is in progress finishes, even if the end of the backup time has passed.
Windows Updates are installed, and Windows Home Server 2011 restarts (if required).
On Sunday, Backup Cleanup runs.
Windows Home Server 2011 does not support GUID Partition Table (GPT) file systems. If you have a computer that is an Extensible Firmware Interface (EFI)-based system and you set it up using the GPT file system system backup, file and folder restore from a backup, and full system restore from a backup are not supported.
Volume Shadow Copy Service (VSS) does not support creating a shadow copy of a virtual volume and the host volume in the same snapshot set. VSS does support creating snapshots of volumes on a VHD, if backup of the virtual volume is necessary. If you want to back up a virtual volume, see the “What are the best practices for backing up VHDs?” section in Frequently Asked Questions: Virtual Hard Disks in Windows 7 (http://go.microsoft.com/fwlink/?LinkId=204720).
