Additionally, mmbackup creates by default a .mmbackupCfg directory on the root 
of the fileset where it dumps several files and directories with the progress 
of the backup. For instance: expiredFiles/, prepFiles/, updatedFiles/, 
dsminstr.log, ...

You may then create a script to search these directories for logs/lists of what 
has happened, and generate a more detailed report of what happened during the 
backup. In our case I generate a daily report of how many files and how much 
data have been sent to the TSM server and deleted for each user, including 
their paths. You can do more tricks if you want.

We execute mmbackup via a regular TSM client schedule with an incremental

mmbackup runs as a preschedule command, and the client -domain parameter is
set only to backup the canary directory. dsmc will backup the canary
directory as a filespace only if mmbackup succeeds (exits with 0). We can
then monitor the canary and infer the status of the associated GPFS
filespace or fileset.

What is the best way of monitoring whether or not mmbackup has managed to
complete a backup successfully?

Traditionally one use a TSM monitoring solution of your choice to make sure
nodes where backing up (I am assuming mmbackup is being used in conjunction
with TSM here).

However mmbackup does not update the backup_end column in the filespaceview
table (at least in 4.2) which makes things rather more complicated.

The best I can come up with is querying the events table to see if the
client schedule completed, but that gives a false sense of security as the
schedule completing does not mean the backup completed as far as I know.

What solutions are you all using, or does mmbackup in 5.x update the
filespaceview table?
