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
