Periodically I use this command ->
WBADMIN START BACKUP -backupTarget:E: -include:C: -allCritical -vssFull -quiet
to make a complete backup of my system drive.
What I've noticed recently is that restoring my system drive from the image has become much slower than it used to be. What I do to restore the image is I choose 'Restore you computer to an earlier time' inside Windows which will reboot my PC and I then choose the image to restore the system drive from.
Before I noticed how my HDD light was constantly ON during the complete restore process indicating full disk activity but now I see the HDD light goes OFF for about 30 seconds or even more several times during the restore process and nothing seems to happen and the restore (although always completing successfully in the end) has become a much slower process.
Any idea what might cause this?
I'm using Windows 7 x64 Ultimate and I've tried starting all over by issuing the wbadmin delete catalog command, choosing the backup drive and delete all restore points and even manually deleting the WindowsImageBackup folder but problem remains.
I've also checked the fragmentation level on my backup drive but running defrag e: /a /v reports the drive doesn't need to be defragmented. My system drive is a SSD drive so fragmentation shouldn't be a problem on that one.
Thanks in advance for any help/suggestions!
