Of course, this very much depends on the tools you are using. Rdump
will push data at a remote file, and the client process can be
initiated from a server by running a command with ssh. It sounds
like you want to pull data with a server, in which case you will
indeed need to remote-mount the files on the server.
But those are all 1980's solutions; expensive, slow, insecure,
inconvenient, inefficient, and a lot of other perjorative adjectives.
At the risk of sounding like a broken record, look at dirvish
( www.dirvish.org ) or some other rsync-based disk-to-disk mechanism.
The savings in effort, cost, and time are spectacular, without even
getting into the security and indexing and ease-of-restore issues.
I gave a dirvish presentation at the PANUG meeting last night, and
like the presentations last year at PLUG and at LinuxFest, it was
well received. I will be giving a similar presentation next Thursday
( 2005-01-27 ) evening at the Oregon IEEE Consultant's Network
meeting, http://www.eeconsult.org/members/presentation.html . Public
meeting, all are welcome - if they can tolerate IHOP food. I also
would be glad to head out to Gresham/Troutdale and present, if someone
provides a venue and an audience of a dozen or more.
Cast OUT those Satanic tape drives! Be reborn in BITS EVERLASTING!
HEAL! :-)
