rsync backup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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% /
tmpfs                   241388         0    241388   0% /dev/shm

[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/

sent 520737900 bytes  received 1810 bytes  7602039.56 bytes/sec
total size is 4010614859  speedup is 7.70

	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
etc/smartd.conf
etc/alsa/asound.state
etc/blkid/
etc/blkid/blkid.tab
etc/blkid/blkid.tab.old
etc/sysconfig/hwconf

[root@k5di]

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.
