I'm using 2.6.* but I'm upgrading to 3.1.0.

I'm running Solaris 10 and I can't use fssnap for UFS becuase it's not 
supported in a cluster evironment. ZFS didn't work out either
because it is using variable block size in the filesystem which breaks part of 
the application so the last resort is using a 3-way mirror
and doing detach stopping the application and then restart it, go through with 
backup and then detach the third-mirror and resync.

What are the improvement for scripting in version 3.1.0 and how can this be 
wrapped into the client ?
Since the filesystem contians a lot of files ( few millions ) I belive that 
ufsdump works better than gtar.

Thanks Gunnar Gunnarsson
