Backup to file server
Does anyone have any modifications to the LMFS backup software that
allow it to use files on a file server as the backup medium instead of
tapes. I've been using the Unix RTAPE server to dump to 9-track
reel-to-reel tapes on a Unix server, but we're phasing out those drives
here; most of our Unix dumps are done on Exabytes. Also, the amount of
data that changes on our LMFS server is little enough that it's hard to
justify wasting a whole tape; I just did a three-month consolidated
backup, and only dumped 28 files.
We have an Epoch InfiniteStorage file server; this is an NFS server with
an optical disk jukebox, to which it automatically migrates and
retrieves files. I'd like to send my dumps to files there, rather than
I already asked Symbolics, and they don't have anything that does this.
They suggested that I mount the LMFS as an NFS server and use tar. But
that will lose version numbers (although I think there's a variable that
can be set to make all version numbers show up) and some file
properties. Also, Unix (or at least SunOS) clients really don't like
slow NFS servers; they can bog down the entire machine, and I don't want
to screw the Unix users while I'm dumping.
