I have one Domain Controller (Windows 2000 Server) that is formatted with NTFS.

I try to restore certain data files (i.e. Word, Excell, Access) using Backup Exec or Microsoft Backup, I notice that some (not all) of the files give access errors when I try to open them from the restored directory(i.e. file cannot be accessed, or "filename doesn't exist).

Upon further review of the properties of each file, I find that the reported "Size on Disk" reports a much lower number (i.e. 4KB) on the origional files than do the restored files. This is the primary difference between the origional file and restored files. Does anyone know why this number might change when a file is restored and if it could be the cause of my problem?

Any help would be appreciated!!

Just a shot in the dark, Terry, but it could be that you're actually running an incremental backup. That is, that each backup to tape only stores the changes made to a file since the last backup.

Hope this helps!

Sounds as if your backups may not be good. Try a new tape. If you get the same results... look at the backup unit. How old it is? How many times have the tapes been used? Errors being written (or retries) may cause a file to grow).

Note: An incremental backup only backsup full complete files that have changed since the last full backup. Incremental backups DO NOT backup part of one file!
