Re: [Networker] Some questions on upgrading
2005-11-09 13:16:34
Can you simply use 'mmrecov' to recover the media database from tape on
a different endian box (Linux), assuming you backed it up using
'savegroup -o groupname -l full' on Solaris? My understanding is that
the media database gets backed up every time the server gets backed up,
so if the server is a member of 'groupname' then you'd have a backup of
the media database on tape, too, so you could then use 'mmrecov' on the
other endian machine? Would this do the same thing?
How would you use uasm?

If in fact the tape format is not endian dependent then it still

using something like 'savegroup -o groupname', and then use 'nsrck
-L7' to recover them to the Linux box they would now be on disk, not
tape, and maybe the NetWorker version on Linux might then read the
indexes differently since the byte order is different, i.e. Linux is
little endian and Solaris is big endian. Wouldn't this still be a
problem?
Is NetWorker endian sensitive? Does it care? A lot of applications
don't care about the byte order, but some do. I can't get a clear
answer from Legato on this.
Hi,
The tape format is independent of byte order, as are client indexes.
The media index is still stored in a binary db form and is therefore
byte order sensitive.
Don't forget about uasm. Think of it like tar, but it runs the same
asm's as the save command and emits byte-order independent save
streams to stdout, which can be saved in a file and read by a uasm on
another machine. I'm just sayin' ...
