The short version (apologies for the long version below):
I wish to restore the full 204GB of data from the 500GB backup set that Norton has on my Backup Drive, but Norton only shows 54GB as available to restore. How can I make Norton restore all files stored in the backup?
A little background;
I run a Windows 7 Ultimate 64bit system.
It has a 120 GB OCZ Vertex 2 SSD boot disk (C:), and a 2 TB Western Digital WD20EARS HDD data drive (D:).
I also have a 1 TB Western Digital WD10EVCS HDD connected via USB as a Backup Drive. I use Norton 360 V5.
A couple of weeks back the boot disk started playing up, and Windows could not repair it. Eventually it refused to boot. I had a Windows system image of the SSD from a couple of months back, and a data backups from the SSD on a backup drive, both using Windows 7 Backup.
My most recent data backup from the SSD was two weeks old, so I pulled the SSD out of the PC and connected it to my laptop, then also connected my backup drive to the laptop. That way I was able to copy the "users" directory from my SSD, including the latest Outlook files which were most important, across to my backup drive so that I could restore them to the SSD once it was repaired or replaced.
I restored the system image to the SSD and restored Outlook, so all was running again.
As Windows Backup doesn't allow multiple backup sets, I use Norton 360 to backup everything on my Data Drive onto my Backup Drive, allowing it to create the N360_BACKUP directory in the root of the Backup Drive. I force a backup of all files and sub-directories by specifically including the data directories on the data drive within Norton 360, since selecting a backup using file types alone misses many files. The data directory that I backup has about 39,851 files and is 204GB. Another temporary directory holds 6198 files and is 127GB. The total disk space used is about 334GB.
Unfortunately while the Backup Drive was connected to the laptop, Norton 360 on the laptop detected the Backup Drive and as it had a valid Backup Set in the installation of Norton on the laptop, and the drive mapped correctly, Norton did a backup to the Backup Drive, creating a second sub-directory under the N360_BACKUP directory in the root of the drive. This was not my intention, and I needed the space, so when I noticed the extra backup I checked the size and date of the two sub-directories and deleted the new one, retaining the older and larger sub-directory.
Unfortunately is seems that the SSD Boot Disk was failing because the Data Drive was failing and locking up programs. One such incident had taken out the SSD causing the problem described above. After fixing the SSD, problems started to become apparent with the Data Drive.
So I check the Norton Backup using Norton 360 Restore (both the main and portable versions of the program), only to discover that it could only restore 742 files or 54GB, so much of my data would not be restored if I ran it. Browsing the available files shows that Norton stopped backing up when it hit the first unreadable file. However, it reported successful backups, so I didn't know there was a problem. I don't know if deleting the new backup sub-directory, or failed backups has caused the problem, but Norton can't restore all my data.
The Norton Backup Preview currently says it could backup 33,573 files and 131.4GB, reflecting the loss of directories that are no longer accessable on the data drive.
The Backup Set takes up a little over 500GB on the Backup Drive at present, and so should hold a copy of all my 204GB of data, rather than just the 54GB it says it has.
So, rather than try a restore straight away I have been slowly recovering files from the failing Data Drive. I now have all the files I can get off it, totalling only 132GB, plus the full 127GB of temporary files. (Wouldn't you know the files I don't really need are the ones I was able to get back.) However not all of the recovered files are reliable. Some photos are corrupted, and I haven't been able to check all the other file types. It is not surprising that I haven't been able to get all files off the drive, as Crystal Disk Info now say the drive is bad with a Read Error Rate attribute of 1, which is the worse reading possible, and well below the threshold of 54. Western Digital Data Lifeguard won't even complete tests against the drive.
So this is my problem:
I wish to restore the full 204GB of data from the 500GB backup set that Norton has on my Backup Drive, but Norton only shows 54GB as available to restore. How can I make Norton restore all files stored in the backup?
