JFI Computing offers a data backup service. This
is available for Linux, FreeBSD, Mac, and Windows
desktops, for servers and computational clusters
of anyone wanting a backup solution in the JFI.
(To begin backup service involving a terabyte or
more of data, a financial contribution to the
system may be required from your group to help pay
costs of expanding the system.)
All of JFI's servers and most of our faculty-owned
systems are currently protected by its
chronological archive of past data, stored by
days, weeks, months, and years, depending on the
retention period being maintained for each
Both of the backup servers (named feynman and
a Perl program which pulls in and retains the
periodic backup snapshots efficiently, without
taking any more space on the server than is
necessary. Many of our backup archives
(especially the backups for our home directory
server) are setup to be retrievable by the users
with no help from us, so that if a user needs to
recover something, they may simply find their lost
files and copy it out of the archive themselves.
While logged in on
can find past incarnations of ones home directory
on NFS-mount at /nfs/feynman.
Also, for the backups of individual Mac desktops
that are being backed up, the personal backups can
be accessed over AFP from the desktop of the user
they belong to, by doing "connect to server" on
the Mac desktop, and connecting to afp://penrose/.
These backups are secure, and are not accessible
to others besides their owner and the IT staff.
Recently, we began doing backups of Windows
desktops. If you would like this service for your
machine, it will require us to install an
additional program on your computer to allow for
connections from the backup server.
When looking at the backups, you will see a list
of "daily", "weekly", and "monthly" snapshots.
Each of these contains the complete state of the
backed up content as it existed at the date of
that folder. Look at each folder's date
information to find the backup snapshot from the
time period you are looking for.
Some types of backups, such as JFI email backups,
can currently only be retrieved with IT staff
If you're interested in getting backup service for
a desktop or server in your research
group, contact us, and
we'll setup a periodic schedule on penrose for
