  • Innobackupex Not Backing Up All Data

    I am new to xtrabackup and mysql for that matter and I doing some initial testing on an ubuntu 11.10 image running in KVM.

    When doing a full backup it does not appear to backup all data schema etc.

    Specifically I have my innodb ibdata files on various NFS mount points and all innodb ibdata files seems to be backed up fine, but in the directory where the data base was created not all data is backed up. This is a simple test DB and under the datadir I have the following sub directories:
    mysql
    performance_schema
    sbtest

    Below is the "ls -l" for what was backed up followed by the "ls -l" of the same directory in the database for each directory.

    FYI - both the full backup and apply log runs "completed OK!".

    Can anyone shed light on this - what am I doing wrong?

    I added the --defaults-file='location of my cnf' to the innobackupex --copy-back command and it now appears to backup all data.

    However, why would I need to do that? I also noticied on the output of the backup where the files where not appropriately backed up the output said they where.

    Below is the saved output of showing it said it copied the files (but indeed it did not). So something seems a tad weird...

      Small typo in prior response:
      I added --defaults-file option to the innobackupex on full back up.

      The wording --copy-back was a "typo" and should have not been there.
