Solved ZFS missing directory

This morning (2020-03-22) I received this message from cron:

Code: 
cp:
/var/spool/backups/ca/harte-lyne/hamilton/vhost06/hll_vhost06_etc_rc_conf.txt:
No such file or directory

However, looking in the root history file I find this:
Code: 
hg mkdir | grep vhost06
2044  2020-03-11 16:23:30: mkdir -p /var/spool/backups/ca/harte-lyne/hamilton/vhost06/
2084  2020-03-12 15:37:01: mkdir -p /var/spool/backups/ca/harte-lyne/hamilton/vhost06/
2129  2020-03-13 17:27:44: mkdir -p /var/spool/backups/ca/harte-lyne/hamilton/vhost06/
2248  2020-03-21 22:43:54: mkdir /var/spool/backups/ca/harte-lyne/hamilton/vhost06/

Checking the file system shows that the directory is indeed missing.

There is nothing in /var/log/cron showing that the directory was removed. The disappearance of this directory is clearly a recurring event. What could be causing it?

Which cron job is this? What is it trying to do? It is probably running cp. Is that missing directory ...conf.txt the source or the target?

I wouldn't expect to see a message in /var/log/cron, it only shows which cron jobs were started, not what they do. For example, one of my cron jobs is my own (self-written) backup software, which creates and deletes many things, every hour or two.

It seems you are running some sort of backup software, on a stock FreeBSD system there is no directory /var/spool/backups. Look at all your crontabs to see which cron jobs there are, and which are non-stock.
 
All of the cron jobs for root are non-stock. This is not a directory structure created by a software package. It is just a place to copy important configuration files so that they can be picked up en-masse by a scheduled rsync . Having written that now I wonder if it is rsync that is the culprit. I will check to see if ther are any --delete flags on any of those jobs that might account for this.
 
Rsync was the culprit. I changed the cron command to remove the - -delete-after option and the directory stopped disappearing.
