i am using xtrabackup for the first time here, to backup a mysql server on fedora 20.
i only have xtrabackup installed and no other percona packages, presently.
innobackupex --user=root --password=mypassword /my/path/to/backups
plus also ran it a 2nd time using sudo.
in both cases, errors were shown in the terminal log.
the 2nd one (using sudo) produced:

can anyone decode this for me? i have not been able to figure out what the cause of the problem is yet.
