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

[Athanasios Dousis]

Andrew,

Thank you for pointing this out.  I removed the old rdiff-backup using
apt-get, and I reinstalled v1.2.6.  I restarted rdiff-backup using the
command:

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

but I still get:
--
Found interrupted initial backup. Removing...

I then deleted /usr/bin/rdiff-backup and
/usr/lib/python2.4/site-packages/rdiff-backup/ and installed v1.2.6
again, with the same error.  I also deleted the contents of the
rdiff-backup-data directory and tried again, with the same error.  I 
then tried to rsync the contents of my /home and /backup/home
directories using:

/usr/bin/rsync -avz --one-file-system --exclude='/home/shared' --delete
/home /backup

and then I retried rdiff-backup using:

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

I still get the same error.  How can I be sure that I've deleted or 
overwritten all the old rdiff-backup files?  Any other suggestions?

Many thanks,
Nasos
