Daily backups of Unix home directories are available to all accounts. You can access them by double-clicking the “ECF_BACKUP_DIRS” icon on your Unix desktop.
You can also access the backups from a terminal window. For example, if you would like to retrieve a file from November 7, 2016:
% cd ~/ECF_BACKUP_DIRS # (~ is a shortcut to your home directory.) % ls 20161101-Nov-01-2016 20161105-Nov-05-2016 20161109-Nov-09-2016 20161102-Nov-02-2016 20161106-Nov-06-2016 20161110-Nov-10-2016 20161103-Nov-03-2016 20161107-Nov-07-2016 20161104-Nov-04-2016 20161108-Nov-08-2016
Select the date you are interested in:
% cd 20161107-Nov-07-2016
Search the directory structure and copy the files you want back to your home directory:
% cp assignment1.c ~/assignment1.c
