During a backup I got the following messages:

Found interrupted initial backup. Removing...
UpdateError lib/dhcp/dhcpd.leases Updated mirror temp file /usbackup/backup-by-rdiff/april/var/lib/dhcp/rdiff-backup.tmp.9233 does not match source
UpdateError log/btmp Updated mirror temp file /usbackup/backup-by-rdiff/april/var/log/rdiff-backup.tmp.25553 does not match source

Anyone know what the Update Error means?

I was backing up

rdiff-backup --exclude-other-filesystems --preserve-numerical-ids --exclude-sockets --exclude /var/mail root@???::/var /usbackup/backup-by-rdiff/april/var
