Thanks to Chris for this reply as below

I've been using it on Solaris 9 for a couple of years. Used it with my
own backup scripts. Then, when I adopted amanda for backups, I wrote a
wrapper for ufsdump for amanda so that I could get backups with snapshots.

I have tried using fssnap in cluster with disksets and filesystem sizes in
range 2 TB and above and its working fine. Only issue which i faced is
that IBM tsm does not support ufssnapshot devices (/dev/fssnap/0) for
image backup .

thanks

Hi folks,

fssnap sounds a nice feature and very attractive to take backup of
filesystems online. Pleae let me know if some one are using it in
production enviroment. How about taking fssnap on very big filesystem for
example 5 TB.

My second question is about using fssnap in a sun cluster setup with
diskset ? is it supported ?

Please share you expereinces with fssnap, and any suggestions

thanks
