Help creating incremental backups using --backup-dir.

[David Miller]

Normally I would use the --link-dest option to do this but I can't  
since I'm rsyncing from a Mac to a Samba share on a Linux box and hard  
links don't work. What I want to do is create a 10 day rotating  
incremental backup. I used the first script example on the rsync  
examples page as a template. The only thing I changed was the  
destination to be a local directory and paths for the other variables.  
when I run the script nothing gets copied into the directories named  
by the day of the week. Each day when the script runs the directory  
with the name of the current week day is created but everything just  
goes into current. and stays there. Can someone post an example that  
does work for what I'm trying to do? Below is the script I'm using.


#-------------------
# directory to backup
BDIR=$HOME/Documents

BACKUPDIR=`date +%A`
OPTS=" -aX --force --progress --ignore-errors --delete --backup -- 
backup-dir=/$BACKUPDIR"

# the following line clears the last weeks incremental directory
[ -d $HOME/emptydir ] || mkdir $HOME/emptydir
/usr/local/bin/rsync3.0.5 --delete -a $HOME/emptydir/ /Volumes/SAMBA/ 
$BACKUPDIR/
rmdir $HOME/emptydir

# now the actual transfer
/usr/local/bin/rsync3.0.5 $OPTS $BDIR /Users/Shared/current
#-------------------

Thanks.
David.
