12 amcheck \- run Amanda self\-checks
30 runs a number of self\-checks on both the Amanda tape server host and
31 the Amanda client hosts.
33 On the tape server host,
35 can go through the same tape checking used at the start of the nightly
37 run to verify the correct tape for the next run is mounted.
40 can also do a self\-check on all client hosts
41 to make sure each host is running and that permissions
42 on filesystems to be backed up are correct.
44 You can specify many host/disk expressions, only disks that
45 match an expression will be checked. All disk are checked if no
50 man page for more details about Amanda.
54 Run the tape server local and tape checks
59 Run the client host checks.
62 Run the local tests (e.g. permissions) on the server host.
65 Run the tape tests on the server host.
68 Enables a destructive check for write\-protection on the
69 tape (which would otherwise cause the subsequent

74 erased (actually depends on the device driver: there is no portable
75 non\-destructive way to check for write\-protection).
78 and is only made if the tape is otherwise correct.
81 Nothing is printed, but mail is sent
82 if any errors are detected.
