[rdiff-backup-users] removing specific files older than

[Sherrard Burton]

forgive me if this has been covered before, but it wasn't clear from the 
documentation whether i could do this, and web searches were basically 
useless.

i have certain files scattered throughout my filesystem, that because of 
their binary nature, have most or all of their contents backed up daily. 
here's the problem: even for a file as small as 50M you could end up 
with 1G of backups every 20 days. my regular --remove-older-than is 
currently set to eight months, mostly because i'm paranoid and disk 
space is pretty cheap. but, relative to their actual size, these files 
occupy a disproportionate amount of "backup space", measured as actual 
file size plus increment sizes. also, these particular files are usually 
only needed in their current state in case of catastrophic failure. if 
they could all be centralized, i could run a separate backup, but that 
is not an option.

my proposed solution:
i would like to be able to use file selection criteria with 
--remove-older-than so that i could shorten the time period for these 
files, in essence only keeping a two or three day backup.

other options:
i am open to other suggestions that might accomplish the same thing.
