Setting World-Writable File Permissions Prior to Preparing the Backup Can Break It

It’s bad practice to provide world-writable access to critical files in Linux, though we’ve seen time and time again that this is done to conveniently share files with other users, applications, or services. But with Xtrabackup, preparing backups could go wrong if the backup configuration has world-writable file permissions.

Say you performed a backup on a MySQL instance configured with data-at-rest encryption using the keyring plugin. On the backup directory, the generated backup-my.cnf contains these instructions to load this plugin that will be used by Xtrabackup while preparing the backup:

backup-my.cnf

[mysqld]
innodb_checksum_algorithm=crc32
innodb_log_checksum_algorithm=strict_crc32
innodb_data_file_path=ibdata1:12M:autoextend
innodb_log_files_in_group=2
innodb_log_file_size=1073741824
innodb_fast_checksum=false
innodb_page_size=16384

Percona XtraBackup Now Supports Dump of InnoDB Buffer Pool

InnoDB keeps hot data in memory on its buffer named InnoDB Buffer Pool. For a long time, when a MySQL instance needed to bounce, this hot cached data was lost and the instance required a warm-up period to perform as well as it did before the service restart.

That is not the case anymore. Newer versions of MySQL/MariaDB allow users to save the state of this buffer by dumping tablespace ID’s and page ID’s to a file on disk that will be loaded automatically on startup, making the newly started server buffer pool as it was prior the restart.

Details about the MySQL implementation can be found at https://dev.mysql.com/doc/refman/5.7/en/innodb-preload-buffer-pool.html

With that in mind, Percona XtraBackup versions …
