Hi all,
 
I'm searching for a good idea how to backup up or archive our important
Document Management System (AIX JFS2). Today we have backed up about 190
Million Files. The Filestructure is the following:
 
There are Filesystems (40 GB) for every mandant on this system:
 
<mandant-a>/00001
<mandant-b>/00001
...
<mandant-k>/00001

In every Filesystem we have circa 1 Million Files. 
 
 
When a  "mandant"-Filesystem ist full the following happens:
-The Filesystem was remouted to the state READONLY
-A new empty Filesystem (40 GB) is created for this mandant with an
increased 5-digit number . New documents are now going to this
filesystem. 
 
What is the best way to backup / archive this system? Some thoughts: Our
backup runs today over 40 hours, TSM DB is growing and growing, and with
backup we've had the problem, that after a crash one Filesystem was
corrupted and after fsck some files/blocks (sorry I'm not a AIX Admin)
are going to the directory "lost+found". But what happens with the
"corrupted" files. I think they will be backed up again and the "good"
backed up Files on TSM expire? If so, this would be a disaster for our
company. 
 
Any hints / suggentions on this issue are appreciate.
 
Boris
