The technical staff performs backups every night starting at 12:30 AM. If you accidentally
delete or change a file and do not discover the error the same day, send
e-mail to
tech@sci.pitt.edu describing
the file you would like recovered.
If you discover the error the same day (i.e. before the next nightly backup
is done), you can quickly recover the file yourself. Each night, a copy
of all files within your AFS volume is backed up to a separate volume pointed
to by the symbolic link called "Backup" in your home directory. You may use
the UNIX command "cd" to get to this volume and its subdirectories
which is a mirror of your home directory for the previous day.
Once you locate the file in question, use the UNIX "cp" command
to copy this file to the appropriate spot in your home directory. See the
"cp" man page for the system that you are logged onto; there are slight
variations between UNIX platforms.
It is faster to recover files yourself from the ${HOME}/Backup directory
whenever possible since it does not involve the staff loading tapes when
time permits.
