David. I have been thinking a lot about this as i have an
interesting
setup that multiple backup servers would be usefull for as well as a
cluster filesystem with redundancy.
I would like to have 1 cluster filesystem with 3 backup server
attached
to it. I have 3 'main' sites and20 satelites and each satilite is
served by these main sites. i would like to put a backuppc server at
each site for that segments backups as that would distribute my
network
load as well as allow the cluster filesystem to retain remote
redundancy. My idea on this was to have just one server do the
nightly
process and disable the nightly process on the other 2 backuppc
servers. they would not need to do the nightly because the first
machine would handle the pool cleanup for all of them on the cluster
filesystem. each machine could share the same pool.
the tricks are 1)finding the right cluster filesystem that you can
set
the number of remote copies so in my case 3 copies, that would
essentially make them all live mirrors. 2) makeing sure that having
multiple servers writing to the filesystem and therefore to the pool
simultaniously would not create any issues and 3) managing
bandwidth on
the cluster filesystem so it does not saturate the connections.
this does not solve the issue of having 1 interface for all the
servers
but pulls all the backups together as a more cohesive solution.
alternatively i was going to get a fancy RAID controller like a DELL
PERC5 or something that can take 512MB of cache memory and allow more
backups to run simultaniuosly but im worried about saturating my T1.
a really issue here is that the prefered method for backups is
rsync and
it has some serious issues with large numbers of files. I have 2GB
of
RAM in my server and im startion to run into issues syncing my
backuppc
machine accross the network because of filecount.

Subject: Re: [BackupPC-users] Multiple BPC CGI interface.
I second some level of modification for mulitserver environments
or
"clustered" backup servers with common SAN/NAS storage. Then
have a
primary backup machine and slaves so that all backups are
managed by
the master and it assignes the job to the appropriate cluster
member
which may be itself.
I would much rather have a master/slave cluster environment than
just an interface that included a number of machines.
This does imply some change to the storage mechanism to allow
multiple users concurrent access to the same fileset or the use of
some cluster filesystem.
I know a lot of people like simplicity but there is.a certain
level
of complexoty neccessary for backuppc to reach the next level.

Subject: [BackupPC-users] Multiple BPC CGI interface.
Has anybody seen or is anybody interested in developing a multiple
server interface for BackupPC?
I've currently got 8 backup servers running, and although I've
got a
back-end system for tracking where client machines are backed
up, a
single CGI interface that managed them all would be ideal.
Thoughts?
