Why are all six of my ntbackups unrecognizable?

I have SIX different windows ntbackup files.  One each for Monday thru Friday and one from a month ago.  The drives failed in the Server and when I tried to run the ntbackup to restore the files I was unsuccessful.  The error was somthing along the lines of "this data or file is UNRECOGNIZABLE and can't be accessed bla bla bla".  I got the data I needed from an offsite backup but I'm really bothered by the fact that ALL SIX backups failed. I mean, what the heck?  Last night at 2:30 a.m. I had an epiphany.  The servers failed hard drives were dynamic.  The two workstations I tried restoring the backup files on were basic drives, not dynamic.  IS THAT WHY ALL SIX BACKUPS FAILED?   I hope so because then I won't be so scared to ever use the windows backup again.  Well, well, was it, was it???  Thanks.

    Is this the first time you have tried to restore from ntbackup?

    It is good practice to check that any backups that are made can be restored from.

    Accepted Solution

    I tried accessing them with the same user and that did not help.

    It is not the first time I've tried to restore from ntbackup.  I'm aware of what good practices are but that is not my job here.  My job is the recover data.

    I also tried restoring them from a computer that has dynamtic drives and that did not work either.  My best guess is corrupted files got backed up do to a failing drive and therefore they won't open.

    Thanks anyways.
