[rdiff-backup-users] independantly writing to the mirror

[Toby Dickenson]

I am hoping to use rdiff-backup in a scenario where I might make independant 
changes to the mirror. 

I intend to use it to maintain a complete remote operating system backup. 
Occasionally I might boot that backup for some other purpose, and may make 
some changes. I hoped that I could then re-run rdiff-backup to erase those 
changes, restoring the backup to a clean copy of the source filesystem. (The 
man page warns that I might be unable to access old revisions after doing 
that, which I can live with.)

Unfortunately I am seeing that it does not always resync all files that were 
changed on the mirror, I guess because the change is not recorded in the 
metadata cache. Is there a way to force it to fully check the mirror 
filesystem? Will that do what I want, or is there some other danger?

Thanks in advance,
