Your home directory is backed up automatically each day to backup server. You can access these daily images by going to:
There you will see directories with names like '
20070804,' which corresponds to the date of the backup.
Inside this directory you'll see another directory named '
tree' corresponds to your home directory. So, in side it you'll see all the files and dictories backed up on that date. This is an 'image' or snapshot of what your home directory looked like at backup time. Backups are taken sometime between midnight and 8am generally.
