TSM backup and ZFS
Vahid Moghaddasi
We have just noticed that none of our ZFS is being backed up by TSM.
As usual, IBM provided no help of any kind.
We would rather to have a TSM server side solution than client side
but Is there a way to backup ZFS with TSM at all, server or client
side?
Thank you,
Sebastian Hanigk
Could the problem be that the TSM backup client does not travers
"filespace" boundaries (in this case mounted file systems)?
On our site, backing up the user's home directories (every user has a
separate ZFS file system) works, but we state explicitly
"/export/home/<user>" instead of "/export/home".

Which is quite understandable. If you'd care to take a look at
the list of supported filesystems for the TSM-client found here:
http://publib.boulder.ibm.com/infocenter/tivihelp/v1r1/topic/com.ibm.itsmfdt.doc/ans50000105.htm#aclsprt
you'd see, that there's no ZFS to be found.

You could go ahead and try what is suggested at "Notes #1." in
the document referred by the above link.

Just for my curiosity... How many users/filesystems do you have?

Nevertheless EMC/Legato managed to support ZFS sor some time now,
and IBM is probably playing games with customers.

A dozen and a bit. Small institute, I know :-)
It would be quite interesting to see the scalability (or lack of) of the
TSM system when confronted with a bigger setup, a few thousand accounts
like our department should be more challenging.
Does anyone here has experience with such a setup?

I find even stranger the fact that while Tivoli 5.4 docs make no mention
to ZFS, Tivoli 5.3 docs refer to it as supported. But only if your platform
is "UNIX", not Solaris, whatever that means:

I've done this, and it works fine. Its somewhat of a pain though,
especially if you have tons of mountpoints, or frequently add
new ones.

If you look at even older versions:
http://publib.boulder.ibm.com/infocenter/tivihelp/v1r1/topic/com.ibm.itsmc.doc_5.2.2/ans5000090.htm#aclsprt
you see that this "zFS" referrs to a OS/390 resp. z/OS filesystem:

NOTE: This post might appear twice, something has gone wrong with
google group.
I am not sure if the zfs or zFS they are referring is the same ZFS
from Sun. In any case, IBM told us that they are "working" on it,
right they are....
We did a work-around which works (we hope) with a script on all
clients that runs by TSM server after the client is backed up. This is
the script:
...
for mount in `zfs mount | awk '$0 ~ /.*\/.*\/.*/ {print $2}'`;
do
dsmc i ${mount} -subdir=yes >> $LOG_FILE
done
...
We have also put VIRTUALMOUNTPOINT in tsm.sys just to see if works.
Thanks,
