backup software recommendations?

[koder]

I like Joseph's use of NULL to avoid backing up tmp files.

Here is my rsync script for backing up a small home network:

#############
##  the line for wiki must be run as root
##############

###############################################
##  Start script here:                       ##
###############################################

# set 'now' to time and date for filename
now=BUDD$(date +%y%m%d)-$(date +%H%M)
mkdir /media/_bu/$now
sudo rsync -avh /var/www/ddwiki/wiki.d/ /media/_bu/$now/wiki.d.bu |
tee /media/_bu/$now/bu.log
rsync -avh /home/koder/ /media/_bu/$now/koder  | tee
-a /media/_bu/$now/bu.log

###############################################
##  End script here:                         ##
###############################################

My mail editor wrapped the line at the tee option.

I locate the system time and date, format it the way I like, then make a
directory in target media. This gives a time stamped folder to store
data in.

The BUDD is Back Up Delta Dawn, the computer I am working with.
I tee the output to a file on the external so I can review what was done
if I desire.

It is relatively simple, easy to understand and readily modifiable.
You could tell it to omit things if you wanted to. For me it is easier
to just grab it all.

I am only backing up personal data since I can rebuild the machine if I
need to.

I need to have it make sure the media is available and abort if it is
not, but that is for later.

I ended up using DAR for a backup I needed to do to a 500G USB drive.  It took roughly 28 hours (USB isn't a very good filesystem interface, especially for 400G of backup data...), but it worked fairly well.

Below is the command I ran (from /, and after dropping the system into single user mode, very important when backing up the root filesystem...)

dar -y9 -s 4G -D -R / -c "/media/disk/Backup-$(date -I)" -Z "*.gz" -Z "*.bz2" -Z "*.zip" -Z "*.png" -Z "*.jpg" -Z "*.jpeg" -P tmp -P mnt -P dev -P proc -P "media/*" -P var/run -P var/lock -P "lib/modules/2.6.*/volatile" </dev/null 2>&1 1>"/tmp/darbackup$(date -I).out" &
