amcheck 命令

常用示例

说明

amcheck performs self-checks on both the Amanda backup server and client hosts before a backup run. It helps identify potential issues that could cause backup failures, such as incorrect tape mounting, permission problems, or unreachable clients. On the server side, amcheck verifies that the correct tape is mounted for the next scheduled backup and checks local configuration and permissions. On client hosts, it confirms that the Amanda client daemon is running and that the backup server has proper permissions to access the filesystems scheduled for backup. The tool is typically run before scheduled backups or manually by administrators to verify the backup infrastructure is ready. Results can be displayed on standard output or sent via email using the -m option. The default behavior runs both client and server checks (-cs). Client checks have a configurable timeout (default 30 seconds) controlled by the ctimeout setting in amanda.conf.
