Hi All,

I've had a new system dropped on me which has its config driven by the vendor 
rather than from the IT end.  As such I'm supposed make a backup recommendation.
The product backs up by using UFS functionality available in Solaris 8.  This 
allows one to issue an fssnap command, which creates a new unix "device" which 
you can then mount and backup.

This example is to backup a snapshot using tar

#  mkdir /backups/home.bkup
# mount -F UFS -o ro /dev/fssnap/1 /backups/home.bkup
# cd /backups/home.bkup
# tar cvf /dev/rmt/0 . 

This one is to back up the raw device using ufsdump

# ufsdump 0ucf /dev/rmt/0 /dev/rfssnap/1 

OK, it looks like we can run a TSM incremental on the block device or an image 
backup on the raw device.  The filesystem in question will contain an Oracle 
database so most things will chage  daily anyway.

Has anyone had experiance with this Snap backup functionality?  any gotchas?  
Do you use the normal incremental backups successfully?  what about images?

Thanks
