Prepare the backup

Before you can prepare the backup you’ll need to uncompress all the files. Percona XtraBackup has implemented --decompress option that can be used to decompress the backup.

$ xtrabackup --decompress --target-dir=/data/compressed/


--parallel can be used with --decompress option to decompress multiple files simultaneously.

Percona XtraBackup does not automatically remove the compressed files. In order to clean up the backup directory you should use --remove-original option. Even if they’re not removed these files will not be copied/moved over to the datadir if --copy-back or --move-back are used.

When the files are uncompressed you can prepare the backup with the --prepare option:

$ xtrabackup --prepare --target-dir=/data/compressed/
Confirmation message
InnoDB: Starting shutdown...
InnoDB: Shutdown completed; log sequence number 9293846
170223 13:39:31 completed OK!

Now the files in /data/compressed/ are ready to be used by the server.
