Doing a staging run setting up a new xtrabackup restore script I'm running into a somewhat cryptic error I can't readily google a solution for.
I'm working with an incremental backup design. During the initial copy back of the last full the an attempt to apply changes to the first incremental is failing with
xtrabackup: error: failed to read metadata from /var/tmp/mysql_backups/inc/day1/xtrabackup_checkpoints
The cited file is present and world readable.
It's contents are
backup_type = incremental from_lsn = 12:4121088784 to_lsn = 12:4121089203 last_lsn = 12:4121089203
Thoughts on what to check from here?
I think I found my problem. My testing server install was an ubuntu mysql default; not percona.
