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
