Problem using HDUP

Miek,
I wonder if you can help me. 
I have been using your excellent utility for a couple of months now, but I
am having a few problems with the remote backup.
Sometimes it works, and sometimes it does not.
It seems to be date dependant (usually starts failing 23 days into the
monthly backup cycle).
When a monthly backup is run on the 1st of the month, the problem goes away.

I was running version 1.6.18 up to today, when I upgraded to 1.6.23.
However, this does not seem to cure my problem.

When a remote backup fails, I get the following message:

	/usr/local/sbin/hdup: sslserver: STARTING BACKUP.
	/bin/tar: Removing leading `/' from member names
	/usr/local/sbin/hdup: sslserver: STARTING BACKUP.
	/usr/local/sbin/hdup: FATAL: Could not create directory: /home.

	/usr/local/sbin/hdup: WARNING: SIGPIPE received, cleaning up!
	/usr/local/sbin/hdup: WARNING: AN ERROR OCCURED!

	Hdup version.:  1.6.23

	Host.........:  sslserver
	Date.........:  31-12-2003
	Scheme.......:  weekly
	Archive......:  sslserver.31-12-2003.weekly.tar.gz
	Encryption...:  yes (rijndael-192, /usr/backups/system/hdup.key)

	                AN ERROR OCCURED!
	                NOTHING WAS DONE!

I don't really understand why it is attempting to create a directory of
"/home".

The config of my local host is as follows:
	[global]
	archive dir = /usr/backups/system

	[sslserver]
	dir = /var/cvs, /var/jtime, /var/www, /var/users, /etc,
/var/spool/mail
	mcrypt = /usr/local/bin/mcrypt
	algorithm = rijndael-192
	key = /usr/backups/system/hdup.key
	proto = /usr/bin/ssh
	proto option = -1 -i /home/nigel/.ssh/identity
	remote hdup = /usr/local/sbin/hdup
	remote hdup option = -c /home/groups/serpentine/backup/hdup.conf

The config file of the remote host is:
	[global]
	archive dir = /home/groups/serpentine/backup

	[sslserver]
	allow remote = yes


Any ideas of what I can do to resolve this problem?

Best regards,

Nigel Green
