[rdiff-backup-users] Moving from rsync

[john stultz]

Something that I think would be helpful in the FAQ would be howto for moving 
from using rsync to rdiff-backup, pointing out some of the subtle 
differences between the arguments.

Currently I mirror nightly two partitions to a firewire disk using:
rsync -ax --delete / /mnt/backup_root
rsync -ax --delete /home/ /mnt/backup_home/

With rdiff-backup I'm guessing the proper arguments would be:

One time conversion to rdiff-backup:
rdiff-backup -f --exclude-other-filesystems / /mnt/backup_root
rdiff-backup -f --exclude-other-filesystems /home /mnt/backup_home

Then a nightly:
rdiff-backup --exclude-other-filesystems / /mnt/backup_root
rdiff-backup --exclude-other-filesystems /home /mnt/backup_home

rdiff-backup --remove-older-than 2W /mnt/backup_root
rdiff-backup --remove-older-than 2W /mnt/backup_home

I believe this will give me the same mirror as rsync does currently, along 
with rdiff-backup-data dir in each partition. Correct? Are there any side 
effects I should expect? (anything else like: 
http://lists.gnu.org/archive/html/rdiff-backup-users/2004-08/msg00019.html  
?)
