I am happy to clarify anything that isn't clear.

I am an astronomer. I am at a university where I do simulations on a
supercomputer. My simulations produce a few hundred gigs of data. One
of the researchers here also doubles as sysadmin, but that is a part
time activity along with his research. We mostly look after our own
computers, including backups.

I said "personal backup" because I have only one computer, and I am
root. Recently the sysadmin decided to add a backup server running
BackupPC. I did not know this when this thread started. Yesterday, he
and I sat down together and setup BackupPC to SSH to my workstation
and backup my home. I am one of the first people in the department to
start using the new backup server.

So, as of now, I have a brand new account with a BackupPC server
running on a separate host, as recommended by the people in this
forum. I hope I didn't waste anyone's time with my questions. It is a
real coincidence that the sysadmin decided to start using BackupPC at
about the same time that I started thinking about it.

I am not sure what the server's setup is, but I'd imagine it is some
sort of RAID.

I just did a quick test: Gzip compressed a sample data file by 35.7%  :-)

I have a spare computer in storage that's not been used for anything.
I think I'll set up a home backup server for me and my wife.

Thanks for the help.

Cheers,
Daniel.
