Max,

It doesn't look like you are doing anything wrong. Here are four  
suggestions:

1) Use a different option to specify which restore point you would  
like, eg, '-r 1B' to specify the newest increment (that is, not the  
current backup, but the one immediately before it). Perhaps /var/mysql/ 
rcm/ does not look as you think it did exactly 72 hours before you  
entered the command.

2) Try not creating the db1 restore target. Rdiff-backup can create  
that directory for you. (Although my testing shows that it will work  
either way.)

3) Try restoring the /var/mysql directory to /tempp/mysql and then  
getting the /tempp/mysql/rcm directory out of that.

4) Run rdiff-backup with -v5 to see more information about the restore  
process.


To answer your other question, no you do not have to restore files to  
their original location. /Volumes/Backup320/var/mysql can be restored  
anywhere.


hope this helps,
Andrew
