[Networker] How to work around a bad tape?
2006-05-15 19:57:15
Is it possible to recover a portion of a save set by pointing it at a
specific tape or telling it not to recover anything from a specific
required volume?
For example, if you need to recover a full save set that spans say 5
tapes, and tape 4 of 5 is a problem tape, you could obviously start the
recover, and then when it gets to tape 4 you could then cancel or simply
not even have that tape loaded to begin with in which case NetWorker
will ask for it, and then you could cancel the recover. Obviously, you
wouldn't end up with everything, but you'd at least have the first 3
tapes, and that *might* be better than nothing. I don't see any way to
do this in the GUI, but is there a command line work around wherein you
could do a save set recover against each good tape by somehow specifying
the file or starting record number? I know save set recover will not
remove data like a browsable recover will so you might end up with extra
files, but that doesn't seem likely in a full restore, only if one or
more incrementals were also specified, and even still that might be
better than nothing in certain circumstances.
Just seems like with save set recover that NetWorker outa be able to
work around one or more required tapes and just pull off whatever is
there, leaving it up to you to deal with the aftermath. If NetWorker
knows where the save set starts on the tape then why should it matter
whether or not it has one or more of the required tapes, except for the
one actual file that spans? Maybe not that simple?
Just curious.
