Re: [ADSM-L] Several simultaneous backups of an AIX client

If multiple file systems you could make sure there's a stream for each,
you could break it in small chunk with more stream using the Virtual
Mount point option then increase the Resource Util and Maxnummp for the
CLIent, other wise tar up all the files and send to TSM but you may end
up backing up stuff that hasn't changed.


Examples Options file: virtualmountpoint /afs/xyzcorp.com/home/ellen
virtualmountpoint /afs/xyzcorp.com/home/ellen/test/data
The virtualmountpoint option defines a virtual mount point for a file
system if you want to consider files for backup that begin with a
specific directory within that file system. Using the virtualmountpoint
option to identify a directory within a file system provides a direct
path to the files you want to back up, saving processing time. It is
more efficient to define a virtual mount point within a file system than
it is to define that file system using the domain option, and then to
use the exclude option in your include-exclude options list to exclude
the files that you do not want to back up. Use the virtualmountpoint
option to define virtual mount points for multiple file systems, for
local and remote file systems, and to define more than one virtual mount
point within the same file system. Virtual mount points cannot be used
in a file system handled by automounter.

Subject: [ADSM-L] Several simultaneous backups of an AIX client

Hello everyone,

I have a situation with an AIX TSM client which is at the 5.5.0.6
release on a TSM server which is on AIX and is at 5.5.1.1.  The client
has 18 million files to inspect when doing a daily incremental backup
that begins at 9PM and as you can see below took almost 11 hours.  As
you can guess this just isn't acceptable to run for this long period of
time.  Does anyone have any suggestions on what could be done in order
to get this server backed up incrementally in a quicker fashion?  Any
suggestions are greatly appreciated!
