Dear all,
I know, it is a little bit out of topic, but we are looking for Software
to archive our data held on
~400GB reiser fs.
We want to have exact one copy on tape of each file that is on our
system at e.g. midnight.
Only new or changed files should go to tape.
Tapes are in an robot system of ~2TB.

The data are on hardware raid, no lvm.
Tar: How to exclude all file the are on tape jet?
Where/How to find old files?
I think of features as seen in legatho, something like a HSM system

How can you without snapshots of the filesystem be able to backup
from one point in time? I mean if the filesystem changes during the
backup you may loose (miss to backup) data that is changing/moving
or get partial files.
Otherwise it should not be such a big problem to use tar to copy
files that are changed after a certain date (last backup). Check
the tar manpage :)

The data to backup are produced during experiments. There is no need to
get all files at a given time.
We only want to have all files on tape some days after creation.

I did this. But how to get file back? How to find them
What about files copied over remote from WIN of created by progs that
reset a and m times?

How do you mean get the file back? The idea with backup is that you
have them in case you loose files, corrupt or overwrite them by
accident?

This is a problem with Samba/Windows. You could make Samba to not
change the access/create times, or control how it should update
them. It is a little tricky though, and might not help.

The problem is: If i have the data written some time ago, find the tape
the file is on.
We have a changer for 48 tapes and it takes some time to check all of them!
You know that usernever know exact data of there files.
So I have to setup mysql for it or somethink like that.

The files are mostly from WIN and we need the original timestamps, that
is the problem.

You could always just buy Legato. It's dealing with all these little
details like keeping indexes of what versions of what files are on what
tapes that make Legato a bit bigger and more expensive than tar or cpio ;)
The *real* fun starts when you have to use more than one tape drive because
otherwise it takes over 24 hours to do a nightly backup...
