## SCRIPT: 00_rsync_bkup_2maxtor.sh    in $HOME/Rsync
##
## PURPOSE: This script uses 'rsync' to backup data files
##          (esp. home directory) --- to an external disk drive.
##
## HOW TO USE: Can make a desktop icon to run this script by
##             simply clicking on the icon ---
##             after the external disk drive is attached and
##             running (powered up).
##
##             BUT ... you will not see the messages from the rsync
##             command unless you set this script up to be
##             run within a terminal window.
##
## (It is good to check the current size of the home directory to see if
##  if fits on the external drive.)

## 'rsync' only copies files that are different. With large files that
## have changed, it only copies the parts that have been altered.
## Its main parameters are a 'from' directory and a 'to' directory.
##
## The '--delete' option removes files not present on the first directory.
## The '--archive' option causes all file permissions and timestamps to be copied to.
##
## The trailing slashes on the directory names are important because they indicate
## that you want to sync the contents of the folders. If you omit them, you could
## end up copying one directory into another.
##
## Since we may be using an MS Windows FAT file system on the 'to' drive,
## we use '--modify-window=1', as explained here:
## --modify-window
##	      When  comparing  two  timestamps, rsync treats the timestamps as
##	      being equal if they differ by no	more  than  the  modify-window
##	      value.   This  is  normally  0 (for an exact match), but you may
##	      find it useful to set this to a larger value in some situations.
##	      In  particular,  when  transferring to or from an MS Windows FAT
##	      filesystem (which represents times with a 2-second  resolution),
##	      --modify-window=1 is useful (allowing times to differ by up to 1
##	      second).
