Hi.

I use amanda to backup a samba share (and other filesystems). I run amverify
after each amdump.
Everything was ok (for month) until amverify (the backup report was ok)
returned:

-----------

Running maveriy by hand returned the same result. I suspected the
tape, and changed it. The verify after the next backup returned the same
problem:

----------------

Both verify runs fail reading the same file on the tape: an image of a 1.28
Gb samba share. I checked both tapes by reading the tapes and files header
blocks.
It does not mean that those files are not corrupted, but this is unlikely.

Is there a size limit to the file that amverify (tar ?) can handle ?

The amanda server runs RHS 7.3, amanda 2.4.2p2, gnu tar 1.13.19, samba
2.0.7.
