Re: Fill a disk with more recent files

With a source disk containing x-amount of space, and a backup disk containing 
y-amount of space, where x > y, to back up files from x, newest first, until
disk y is full, it's as simple as a bash-loop where you specify date ranges on
each iteration:
 
for days in {1..30}; do
find source/ -type f -mtime -${days} -exec rsync --archive '{}' target/'{}' \;
done

- or -

for days in {0..30}; do
find source/ -type f \( -mtime +${days} -mtime -$(($days + 1)) \) -exec tar cf - '{}' + |
  tar xvf - -C target/
# and use '--strip-components n' to remove leading paths on target
done

There are advantages and disadvantages to each.
