I've used rsnapshot for many years with no problem, but suddenly I've

I've looked in /var/run and cannot find the rsnapshot2.pid referred to
above. I run rsnapshot with a variety of different conf files, but they
are all behaving the same way.
I've also looked for a running rsnapshot or rsync process in top, but
there is none.
Apart from reading my crontab a day or two ago (not writing/editing it) I
cannot think of anything I might have done to trigger this behaviour.
What does your rsnapshot log file show about the previous run? Had it
completed by then or has an increase in data to be backed up resulted
in it over-running the next interval?
This is the log of the latest hourly run:

I'm not sure whether these logs are helpful, but will try increasing the
interval between jobs in crontab, and see if that fixes the problem. So, here
is my new crontab entry, increasing the intervals between hourly, daily,
weekly and monthly from 10 minutes to 20 minutes:
# Backup schedule to /castor every 4 hours:
0 2,6,10,14,18,22 * * * root /usr/bin/rsnapshot -c /etc/rsnapshot.conf2 hourly
40 1 * * * root /usr/bin/rsnapshot -c /etc/rsnapshot.conf2 daily
20 1 * * 6 root /usr/bin/rsnapshot -c /etc/rsnapshot.conf2 weekly
0 1 1 * * root /usr/bin/rsnapshot -c /etc/rsnapshot.conf2 monthly
Thanks,
Bob
