Hi everybody,
I’m using Streaming and Compressing Backups to perform my backup on a MariaDB 10.19:
$ innobackupex --user=$db_user --password=$db_pass --compact --stream=tar ./ --no-timestamp | gzip - > $WORKING_DIR/$BCK_FILE
All seems ok even when I restore the backup, innobackup output shows:
...
innobackupex: Finished copying back files.
160801 13:52:31 innobackupex: completed OK!
but when I start the mysqld I find the next message in its log:
2016-08-01 15:52:33 7f08d8ed87c0 InnoDB: Error: page 371 log sequence number 2340146
InnoDB: is in the future! Current system log sequence number 2337804.
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files. See
InnoDB: http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html
InnoDB: for more information.
...
a lot of times!
In some cases I can’t initialize the mysql.
On the page 23 of the manual ‘PerconaXtraBackup-2.1.9.pdf’ you can read:
‘Note that the streamed backup will need to be prepared before restoration. Streaming mode does not prepare the backup.’
I have no idea of how prepare the backup before the restoration in this situation.
In the manual explains how prepare it using --apply-log argument but the backups aren’t performed using stream and compressing mode.
Anybody knows how prepare it correctly?
How can I retore it?
Should I use the --apply-log to prepare it? How?
Thanks for your time.
Best rgrds,
Boadrius
