Incremental backup tar error

view story

http://stackoverflow.com – I'm making a backup system. I have 2 servers : the main sends data to the backup server, then, the backup server compress the data. To save disk usage, I just compress the files that have changed thanks to a flag-file that stores the last backup time. Sometimes it works fine, but sometimes my script is exiting with an error 123This error is comming from xargs The description is : 123 if any invocation of the command exited with status 1-125 So the command I launch is : find /home/* -name "." -not -path "/home/*/www/cache/*" -not -path "/home/*/www/cc/cache/*" -not -path "/home/*/www/ot/ca (HowTos)
