Re: [rdiff-backup-users] cron job opens and closes ssh without copying.

[roland]

hello chris,

check for envvars differences between the user-account (you are testing 
with) and the cron-job.
it's a common pitfall with cron that jobs don`t run properly due to missing 
environment variables.
put your command in a wrapper-script "backup.sh" and eiter put "set 
>/tmp/env.txt" before rdiff-backup command
(or put backup.sh >/tmp/backup.log in crontab)

regards
roland
