6 amdump - back up all disks in an Amanda configuration

10 [--exact-match] [-o configoption...] config [host [disk...]...]
11
13 Amdump is the main interface to the Amanda backup process. It loads the
14 specified configuration and attempts to back up every disk specified by
15 the disklist(5). Amdump is normally run by cron.
16
17 The command optionally takes a set of DLE specifications (see amanda-
18 match(7)) to narrow the DLEs that will be dumped. All disks are dumped
19 if no expressions are given.
20
21 If a file named hold exists in the configuration directory, amdump will
22 wait until it is removed before starting the backups. This allows
23 scheduled backups to be delayed when circumstances warrant, for
24 example, if the tape device is being used for some other purpose. While
25 waiting, amdump checks for the hold file every minute.
26
27 In some cases it is desirable to dump all Amanda clients to holding
28 disk without writing anything to storage media. The --no-taper option
29 instructs Amanda to not start the taper, and thus enter degraded mode
30 immediately.
31
32 See the amanda(8) man page for more details about Amanda.
33
35 --no-taper
36 Disable writting to tape, including flush and vault.
37
38 --no-dump
39 Disable dump operations.
40
41 --no-flush
42 Disable flush, like setting autoflush to NO for all storages.
43
44 Dump done in this run will be flushed.
45
46 --no-vault
47 Disable all vault.
48
49 --exact-match
50 The host and disk are parsed as exact values.
51
52 -o configoption
53 See the "CONFIGURATION OVERRIDE" section in amanda(8).
54
55 host [disk]*
56 Specify the host and disk on which the command will work -- see the
57 description of DLE specifications in amanda-match(7).
58
60 Here is a typical crontab entry. It runs amdump every weeknight at 1
61 a.m. as user bin:
62 0 1 * * 1-5 bin /usr/local/sbin/amdump daily
63
64 Please see the crontab(5) or crontab(1) manual page for the correct
65 crontab format for your system.
66
68 amdump: waiting for hold file to be removed
69 The "hold" file exists and amdump is waiting for it to be removed
70 before starting backups.
71
72 amdump: amdump or amflush is already running, or you must run amcleanup
73 Amdump detected another amdump or amflush running, or the remains
74 of a previous incomplete amdump or amflush run. This run is
75 terminated. If the problem is caused by the remains of a previous
76 run, you must execute amcleanup(8) and then rerun amdump.
77
79 The exit code of amdump is the ORed value of:
80 0 = success
81 1 = error
82 2 = a dle give strange message
83 4 = a dle failed
84 8 = Don't know the status of a dle (RESULT_MISSING in the report)
85 16 = tape error or no more tape
