A Dell T110 II Server with a pair of freshly installed and initialised SAS RAID 0 disks had to be restored from Windows Backup image stored on an external HDD.
The "Scanning for System Image disks.." process took a very long time. Two backup disks were tried (both in Vantec USB3 enclosures attached to the T110 USB2.0 ports) and both exhibited the same behaviour. Ultimately one backup disk was transferred into an eSATA enclosure and the "Scanning..." process took in the order of 1 hour or more to complete.
This is an undesirable delay which I would like to avoid in the future. Can anyone explain why the scanning process takes so long? I am only expecting the restore process to need to locate the \WindowsImageBackup\(server)\ directory and identify the requisite files there. My first guess is that the entire backup set is being read off disk for some reason - based on the length of time taken being commensurate with the size of the backup set and an average of 100MB/s disk read speed,
I have previously performed a bare-metal restore on an Intel Server/Windows 2008 R2 system with the backup image stored on an installed SATA disk and don't recall experiencing any significant delay in locating the backup image.
These backup disks are 512-byte sector disks. Is it something to do with the way they are formatted? Or could it be something else entirely (the "empty" virtual disk volume in the Dell? What else could it possibly be?).
