rsync backup

[Karl Larsen]

	Here is the most basic use of rsync to perform backup of your computer. 
This is very easy to understand and that is why I did it. Below is a 
bash file that calls rsync with the -avg filters and it sets up the 
things to be backed up. I stopped backing up /sys because it has some 
things that do not want to be copied.

# This is the rsync bash file for root

rsync -avg /home/ /media/disk/

rsync -avg /etc /media/disk/

rsync -avg /usr /media/disk/

rsync -avg /boot /media/disk/

rsync -avg /var /media/disk/

rsync -avg /bin /media/disk/

rsync -avg /lib /media/disk/

rsync -avg /root /media/disk/

rsync -avg /sbin /media/disk/

# rsync -avg /sys /media/disk/

	Last evening it took about an hour for rsync to backup all this stuff 
and put it on the USB connected hard drive at /media/drive/. Here is 
what it looked like this morning.


[root at k5di disk]# df

The portable hard drive is too small. I need to get a bigger one. You 
can see the backed up directories on the portable disk drive. As the 
first incremental backup is started you see things like this:

karl/work/thunderbird/
karl/work/thunderbird/updates/0/

total size is 4010614859  speedup is 7.70

	In /home/karl/ there was just a small amount to back up.

etc/aliases.db

etc/resolv.conf

	So you see the first incremenmtal backup was just about 5 minutes in 
duration. All this needs to be saved while we design a better way to do 
this.
