Curtis,
You won’t be proven wrong unless
someone does some serious voodoo and all the planets and starts align exactly
right. Even so the process would not be repeatable. Not to get real technical,
but the reason is the way the file systems are written, NTFS verse any other FS
equals no reliable restore. LINUX is backed up with a STANDARD policy, and
Windows is backed up with the WINDOWS-PC policy for a reason and that was in
the previous sentence.
Now you may restore LINUX to a FAT
partition and have some luck, but I haven’t really tested it, so YMMV.
Thanks,
Rockey J. Reed

Restoring windows NBU backup to linux/UNIX usingGNUtar
I’d love to be proven wrong, but we
looked into this a while back, and it looks like you can’t recovery a
Windows NBU backup on Linux using GNUtar.

Subject: [Veritas-bu] Restoring
windows NBU backup to linux/UNIX using GNUtar
I
just saw this in another forum and was curious if anyone has an answer.
It seems likely the E, U, Q, T are probably drive letters from Windows that of
course mean nothing in Linux/UNIX.
NOTE:
The
question is NOT how to do alternate path restore using NBU – it
is
specifically asking can the tape be extracted using GNU-tar on a Linux (Centos
4) box:
The
OP’s Q:
I can find
a tar readable file header using "tar -tvf /dev/tape1 -b 500" but
unfortunatly the directory appears to be corrupted.
I am attempting to recover a windows backup onto centos 4.
I get the following output from tar;
tar: Record size = 128 blocks
