Guruz!

3 options 3 different answers... ;)
But thanks anyway!

If I'd choose option 3 and I'll have to restore
the file systems from the tape than how I can
boot up the system after the restore?
It won't find the metadbs. Or should I also
backup the metadb partitions?

Sorry for the stupid questions, I just don't
want to ruin our production servers, and I
didn't find any official document on this
subject... :(

Thanks in advance!

Regards,

John
