Hello I wrote a script shell to make backups. First, I execute my script "manually" ans there is no problem. In a second part, I wrote a crontab to launch my script as there : 31 11 14 11 * /home/gldavid/Coding/Shell/Backup/keepme.sh My problem is when the script is launched by cron, I have an error in my log and my backup is not effective : rsync: getaddrinfo: 873: Name or service not known rsync error: error in socket IO (code 10) at clientserver.c(94) Is there a solution to correct this ? Thank you very much for answer. Have a nice day. David
