In regard to: Re: [Networker] any tips for backing up enormous sparse...:
These are holey files according to uasm ?
" holey
The holey ASM handles holes or blocks of zeros when
backing up files and preserves these holes during
recovery. On some filesystems interfaces can be used
to find out the location of file hole information.
Otherwise, blocks of zeros that are read from the file
are skipped. This ASM is normally applied automatically
and does not need not be specified."
It sounds to me like networker applies this directive automatically but
needs to read all the blocks of 0 but not transfer them. Not sure what
the point is then.. Perhaps try specifying this directive anyway.
Thanks for pointing out this directive. I didn't know about it.
I tried setting it explicitly, and it doesn't appear to have made any
difference. I had other directives in the .nsr file that were noticed
and acted upon, so I believe my .nsr file was correct.
In this particular case, we can probably get by with running the "lastlog"
command, dumping the output to a file, and then skipping the real lastlog
file. That works in this case, but won't work in general for large sparse
files.
Thanks,
Tim
