Re: [rdiff-backup-users] trying to restart rdiff-backup after failure without deleting entire mirror

[Athanasios Dousis]

Maarten, Jakob,

Thanks for your quick responses and suggestions.  I'm using v1.1.5 in 
Ubuntu 6.06.2 with kernel 2.6.21 on an Intel Xeon system.  I have python 
2.4 installed.

When I delete the rdiff-backup-data directory and then try the force 
argument as such:

/usr/bin/rdiff-backup --exclude-other-filesystems --force /home /backup/home

I get the following message:

---

How do I empty the rdiff-backup-data directory without deleting it? 
Also, do you have any further suggestions for how to fix my situation?

Thanks and kind regards,
Nasos
