Hi Todd,

Its been a while ...

To the best of my knowledge there is not such a tool.  Part of the
reason a tool doesn't exist is that there would not be a lossless
conversion from dump to either tar or zip.

Assuming that the dump contains the full contents of a volume (not an
incremental) it would be possible to transfer the directory tree, file
data, and symlinks.  However, mount points and AFS specific metadata
including ACLs, policy bits, etc. would be lost.

Yes.  dumpscan and restorevol can process dump files.

Teradactyl's TiBS backup system can I believe import AFS dumps and
restore to non-AFS file systems.

There have also been several uncompleted projects that permit dumpfiles
to be mounted as if they were ISOs on Linux and Windows.

Perhaps it would be useful if you could discuss the end goal of the
conversion.  For example, you might describe the problem as:

   UNC is shutting down its cell and we have 20+ years of volume
   dumps as backups.  We would like to be able to access the
   contents of these backups without deploying a new cell.

Sincerely,

Jeffrey Altman
