I once made --remove-older-than part of my automated backup tasks. But the
amount of time it took to complete execution went up to at least 30+ hours
(I have months of backup history). This coupled with the fact that it is a
remote backup, just made the execution time worst.

In the end, I removed it from my backup tasks and just allow rdiff-backup to
eat up HDD space. HDD space is cheap, time is not.

Subject: [rdiff-backup-users] Expected remove-older-than execution time?

I started a --remove-older-than run on my backup server to remove a 
large number of increments (hundreds). The command has been running for 
over 24 hours now. Is this expected? If not, is it safe to cancel the 
command and run it again with a smaller number of increments? 
(rdiff-backup version 1.0.5 on CentOS 4.)

Also, I finally got around to uppgrading my Debian server to etch, but 
the rdiff-backup version in etch is 1.1.5. Is it possible to use this 
version with my backup-server running rdiff-backup 1.0.5?

Thanks,
Jan

You can decide for a fixed amount of time to backup and do a "--remove-older-than" on a daily basis.
So, for example, if you want to keep the last 6 months of diffs you can use something like "... --remove-older-than 6M", but doing that daily you'll be removing only a day worth of diffs (what will be much faster).
