I'd understood that the OS native dump could handle
correctly certain types of files that tar couldn't. Not an
issue of binaries but rather other types of special files.
Is this or was this true ?
Well POSIX 1.e ACLs are one of them.

Looking at it now, I see that the basic approach is to have the
Amanda client do compression, with the compression program
(GZIP= environment variable to configure) being a script that,
during backups, does essentially gpg -e | gzip, and during
I currently have a 21-tape changer I'm using and it seems
that if I use less than one tape, it doesn't matter, even if
I only use one block on the tape, AMANDA still goes to the
next tape for the next run. This limits me to a 21-day
tapecycle if I'm not mistaken. Any way around this?

1. Reading it all in and then writing it all back out

What filesystem on the target, and what linkage/transport,
samba or amanda client?
Amanda server is on the same machine as the client, it's
backing up to itself with straight GNU tar. FS is ext3.
However, it is exported by SAMBA, if that has anything to
Gene Heskett on Wed 24/12 10:47 -0500:
AFAIK, samba doesn't support those times. So you will, if
samba is the transport from client to server, get a full

experience with the samba 2.x family, and I have not yet
installed 3.0, based

I've heard this before. What exactly is the problem with

Primarily its a security issue because *any* machine can
be localhost. By using the FQDN, there is then no
ambiguity as to which machine is being addressed.

But if you only have one computer and it is the server and

I understand raitcan only work with single tape units and

I don't think it can treat a whole changer as a device.

John R. Jackson on Sun 26/01 17:40 -0500:
You describe RAID4, probably the least commonly used RAID, since it
means only one write request can be satisfied at once, as there is a
