29 runs a number of self\-checks on both the Amanda tape server host and the Amanda client hosts\&.
31 On the tape server host,
33 can go through the same tape checking used at the start of the nightly
35 run to verify the correct tape for the next run is mounted\&.
38 can also do a self\-check on all client hosts to make sure each host is running and that permissions on filesystems to be backed up are correct\&.
40 You can specify many host/disk expressions, only disks that match an expression will be checked\&. All disks are checked if no expressions are given\&.

55 Run the client host checks\&. Multiple specific clients can be checked by specifying the client name\&.
60 Run the local tests (e\&.g\&. permissions) on the server host\&.
65 Run the tape tests on the server host\&.
70 Enables a DESTRUCTIVE check for write\-protection on the tape (which would otherwise cause the subsequent
72 to fail)\&. If the tape is writable, this check causes all data after the tape label to be erased\&. If the
74 option is enabled, this check may ERASE any non\-Amanda tape in the drive or changer\&. The check enable the tape tests on the server host and is only made if the tape is otherwise correct\&.
79 Nothing is printed, but mail is sent if any errors are detected\&. The mail goes to the
