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@k5di disk]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb6 39674192 7651488 29974820 21% /

/dev/sdg1 9614116 7538928 1586816 83% /media/disk
[root@k5di disk]# ls
bin boot etc karl lib root sbin sys usr var
[root@k5di disk]#
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/

In /home/karl/ there was just a small amount to back up.
etc/
etc/adjtime
etc/aliases.db
etc/mtab
etc/printcap
etc/reader.conf
etc/resolv.conf
etc/resolv.conf.predhclient

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.
