I performed a restore of my C: drive (10Gb of data), and ended up with three copies taking up 30Gb! As part of my trials and tribulations in this thread: http://www.wilderssecurity.com/showthread.php?t=195198 I performed a restore of all files from a full backup 2 weeks ago. The Acronis backup file was on my E: drive, and I restored to C:\TestRestore. The screen shots below illustrate: The Acronis backup archive file contained only DriveC. The restore process created Drive(C), Drive(D) and Drive(E) all with nearly identical content. When I tried to delete the C:\TestRestore directory, it failed due to 12 files (4 files x 3 "drives") which cannot be deleted. Additional notes: My D: drive is an empty CD-ROM drive. It took me quite a while to manually delete the 300,000 deletable files in the Drive(C), Drive(D) and Drive(E) directories. I tried using regsvr32 /u on each of the undeletable files, but I still could not delete them -- even after a reboot. To confirm that the duplicated files weren't aliases, I edited one of them in Drive(C) and confirmed that the other copies in Drive(D) and Drive(E) did not change. I also confirmed that free space on C: went down by 30Gb (not good, since it's only a 60Gb drive). I'd like to get answers to these questions: How can I delete these restored .dll and .ocx files? How in the world could this restore behave so terribly as to turn 10Gb of backup data into 30Gb of restored data?
