What does "gzip -vt bla.tgz" say?

Dump and restore (the ext2fs variants) are notoriously broken on Linsux.
Do not use them. Use tar on Linux with ext2 or use xfs and xfsdump. (xfs
on a LVM with snapshoot and freeze features is quite nice.)

I have a programm somwhere that creats tape image files. It detects the
proper tape block size automagicly. Maybe you can copy the tape files to
disk files and use restore on the disk files?
