DESCRIPTION

20       Amfetchdump pulls one or more matching dumps from tape or from the
21       holding disk, handling the reassembly of multi-tape split dump files as
22       well as any tape autochanger operations. The dump are by default
23       decompressed and decrypted.
24
25       It will automatically use the Amanda catalog to locate available dumps
26       on tape, in the same way that the find feature of amadmin(8) lists
27       available dumps.
28
29       The hostname, diskname, datestamp, and level dump specifications are
30       further described in amanda-match(7). Note that at minimum a hostname
31       must be specified.
32
33       Unless -p is used, backup images are extracted to files in the current
34       directory named:
35
36       If a changer error occurs, or the -d option is given, then amfetchdump
37       prompts for each required volume.

OPTIONS

42       -p
43           Pipe exactly one complete dump file to stdout, instead of writing
44           the file to disk. This will restore only the first matching
45           dumpfile (where "first" is determined by the dump log search
46           facility).
47
48       -h
49           Output the amanda header as a 32K block to same output as the
50           image.
51
52       --header-fd fd
53           Output the amanda header to the numbered file descriptor.
54
55       --header-file filename
56           Output the amanda header to the filename.
57
58       -d device_or_changer
59           Restore from this device or changer instead of the default,
60           prompting for each volume.
61
62       -O directory
63           Output restored files to this directory, instead of to the current
64           working directory.
65
66       -c
67           Compress output, fastest method available.
68
69       -C
70           Compress output, smallest file size method available.
71
72       --decompress
73           Always do the decompression, this is the default.
74
75       --no-decompress
76           Never do the decompression.
77
78       --server-decompress
79           Do the decompression only if the compression was done on the
80           server.
81
82       --client-decompress
83           Do the decompression only if the compression was done on the
84           client.
85
86       --decrypt
87           Always do the decryption, this is the default.
88
89       --no-decrypt
90           Never do the decryption.
91
92       --server-decrypt
93           Do the decryption only if the encryption was done on the server.
94
95       --client-decrypt
96           Do the decryption only if the encryption was done on the client.
97
98       --exact-match
99           The host and disk are parsed as exact values
100
101       --extract
102           Extract the backup on the server in the directory directory.
103
104       --directory directory
105           Where to extract the backup with the --extract option.
106
107           Warning: All files in that directory can be removed.
108
109       --data-path amanda|directtcp
110           The data path to use with --extract, the default is to use the
111           fatest data path.
112
113       --application-property NAME=VALUE
114           Application property to send to the application with --extract.
115
116       -l
117           Leave dumps in the compressed/uncompressed and
118           encrypted/unencrypted state in which they were found on tape. It is
119           a synonym for --no-decompression --no-decryption
120
121       -a
122           Assume that all tapes are already available, via tape changer or
123           otherwise, instead of prompting the operator to ensure that all
124           tapes are loaded.
125
126       -n
127           Do not reassemble split dump files at all, just restore each piece
128           as an individual file.
129
130       -o configoption
131           See the "CONFIGURATION OVERRIDE" section in amanda(8).

EXAMPLES

134       All the examples here assume your configuration is called SetA.
135
136       Here's a simple case, restoring all known dumps of the host vanya to
137       the current working directory.
138       $ amfetchdump SetA vanya
139
140       A more likely scenario involves restoring a particular dump from a
141       particular date. We'll pipe this one to GNU-tar as well, to
142       automatically extract the dump.
143       $ amfetchdump -p SetA vanya /home 20051020 | gtar -xvpf -
144

CAVEATS

146       Amfetchdump is dependent on accessing your server's config, tape
147       changer, and (normally) dump logs. As such, it's not necessarily the
148       most useful tool when those have all been wiped out and you desperately
149       need to pull things from your tape. Pains have been taken to make it as
150       capable as possible, but for seriously minimialist restores, look to
151       amrestore(8) or dd(8) instead.
