Have you looked at the "rsnapshot" package?

In words, if the amount of the previous full backup 
is less than free space, nuke the oldest full backup,
and check again.

You could write that in shell/perl/python,
using rsync to make the backups.

Greetings,

Joel

This isn't tested, just typed into mutt, so I might have some syntax
errors.

#!/bin/bash

if [[ ! -d ~/.backup ]]; then
   mkdir ~/.backup
fi

FreeSpace=$(df -PB1 ~/.backup|awk 'NR==2 {print $4}')
FileSize=$(stat -c='%s' $1)

if (( $FileSize >= $FreeSpace )); then
   # No room to copy file. Clear out oldest file
   rm $(ls -tr ~/.backup|tail -n 1)
fi

cp $1 ~/.backup/$1.$(date +'%Y%m%d')

Eliminating race conditions etc are left as an exercise for the reader
:)

Keeping backups until storage runs short (deja-dup style) with command line tools?

Hi,

deja-dup has an option to keep backups forever or until storage on the drive 
backed up to runs short (at which point it starts deleting old backups). 
Does someone have any pointers on how to copy that behavior using duplicity 
and/or other CLI tools?

Cheers, Joh
