I have and old dump format backup done under fedora 7 which is stored on
disk and has an sha256sum file that indicates there are no data errors
in the backup file. When I try to read the file with restore under
CentOS 6, I get the following error:
cat /etc/redhat-release
CentOS release 6.10 (Final)
restore tvf u1_l0_04-29-09_md1.dump Verify tape and initialize maps
Input is from a local file/pipe
Checksum error 20311110402, inode 0 file (null)
restore: Tape is not a dump tape
I have another copy of the backup on another disk with the same checksum
and it gets the same error as well.
Here's a log file from when the backup was done back in 2009:

Have there been any changes to the format of dump files and if so, is
there a version available that can read this older backup? Any other
suggestions on how to read this backup would be helpful.
Thank You,
Nataraj
