Percona XtraBackup supports storing the backups history on the server. This feature was implemented in Percona XtraBackup 2.2. Storing backup history on the server was implemented to provide users with additional information about backups that are being taken. Backup history information will be stored in the PERCONA_SCHEMA.XTRABACKUP_HISTORY table.
To use this feature three new innobackupex options have been implemented:
Backup that’s currently being performed will NOT exist in the xtrabackup_history table within the resulting backup set as the record will not be added to that table until after the backup has been taken.
If you want access to backup history outside of your backup set in the case of some catastrophic event, you will need to either perform a mysqldump, partial backup or SELECT * on the history table after innobackupex completes and store the results with you backup set.
User performing the backup will need following privileges:
This table contains the information about the previous server backups. Information about the backups will only be written if the backup was taken with innobackupex --history option.
