红帽全球峰会第 2 章 Automated recovery from manual backups
You can automatically restore data from manual backups when MicroShift fails to start by configuring automatic recovery.
Use automatic recovery options to store all of your backups in a single directory, then automatically select the latest one to restore. Modifying existing backup and restore commands enables you to set up automatic recovery.
The --auto-recovery option treats the PATH argument as a path to a directory that holds all the backups for automated recovery, and not just as a path to a particular backup file. You can use the --auto-recovery option with both backup and restore commands.
-
For example, if you use the automatic recovery option with
restore, such as inmicroshift restore --auto-recovery PATH, running the modified command automatically selects and restores the most recent backup. -
If you use the same option in the
microshift backupcommand, such as inmicroshift backup --auto-recovery PATH, a new backup is created in the PATH. -
By default,
microshift restore --auto-recovery PATHcreates a backup of the failed MicroShift data inPATH/failed. You can add the--dont-save-failedoption to disable the creation of failed backup data.
重要
You can only use the --dont-save-failed option with the restore command.
