DESCRIPTION
       Amfetchdump pulls one or more matching dumps from tape or from the
       holding disk, handling the reassembly of multi-tape split dump files as
       well as any tape autochanger operations. The dump are by default
       decompressed and decrypted.

       It will automatically use the Amanda catalog to locate available dumps
       on tape, in the same way that the find feature of amadmin(8) lists
       available dumps.

       The hostname, diskname, datestamp, and level dump specifications are
       further described in amanda-match(7). Note that at minimum a hostname
       must be specified.

       Unless -p is used, backup images are extracted to files in the current
       directory named:

       hostname.diskname.datestamp.dumplevel

       If a changer error occurs, or the -d option is given, then amfetchdump
       prompts for each required volume.

OPTIONS
       -p
           Pipe exactly one complete dump file to stdout, instead of writing
           the file to disk. This will restore only the first matching
           dumpfile (where "first" is determined by the dump log search
           facility).

       -h
           Output the amanda header as a 32K block to same output as the
           image.

       --header-fd fd
           Output the amanda header to the numbered file descriptor.

       --header-file filename
           Output the amanda header to the filename.

       -d device_or_changer
           Restore from this device or changer instead of the default,
           prompting for each volume.

       -O directory
           Output restored files to this directory, instead of to the current
           working directory.

       -c
           Compress output, fastest method available.

       -C
           Compress output, smallest file size method available.

       --decompress
           Always do the decompression, this is the default.

       --no-decompress
           Never do the decompression.

       --server-decompress
           Do the decompression only if the compression was done on the
           server.

       --client-decompress
           Do the decompression only if the compression was done on the
           client.

       --decrypt
           Always do the decryption, this is the default.

       --no-decrypt
           Never do the decryption.

       --server-decrypt
           Do the decryption only if the encryption was done on the server.

       --client-decrypt
           Do the decryption only if the encryption was done on the client.

       --init
           Prepare for a restore, some device require it for faster restore.

       --no-restore
           Do not start the restore, useful with --init.

       --exact-match
           The host and disk are parsed as exact values

       --extract
           Extract the backup on the server in the target path.

       --directory directory
           Deprecated, use --target

       --target target
           Where to extract the backup with the --extract option.

           Warning: All files in that path can be removed.

       --data-path amanda|directtcp
           The data path to use with --extract, the default is to use the
           fatest data path.

       --run-client-scripts
           Run the client script if it is set.

       --prev-level level
           The previous level that was restored for this dle. If not set, run
           the pre-recover script. If set, run the inter-level-recover script.

       --next-level level
           The next level we will restore for this dle. If not set, run the
           post-recover script.

       --application-property NAME=VALUE
           Application property to send to the application with --extract.

       --include-file file
           The name of a file to restore.

       --include-list filename
           The name of a file containing file to restore.

       --include-list-glob filename
           The name of a file containing file to restore using
           --include-list-glob of the application.

       --exclude-file file
           The name of a file to exclude from the restore list.

       --exclude-list filename
           The name of a file containing file to exclude from the restore
           list.

       --exclude-list-glob filename
           The name of a file containing file to exclude from the restore list
           using --exclude-list-glob of the application.

       --release-tapes
           Release the tapes already reserved for the restore.

       --reserve-tapes
           Reserve the tapes needed for the restore.

       -l
           Leave dumps in the compressed/uncompressed and
           encrypted/unencrypted state in which they were found on tape. It is
           a synonym for --no-decompression and --no-decryption

       -a
           Assume that all tapes are already available, via tape changer or
           otherwise, instead of prompting the operator to ensure that all
           tapes are loaded.

       -n
           Do not reassemble split dump files at all, just restore each piece
           as an individual file.

       -o configoption
           See the "CONFIGURATION OVERRIDE" section in amanda(8).

EXAMPLES
       All the examples here assume your configuration is called SetA.

       Here's a simple case, restoring all known dumps of the host vanya to
       the current working directory.
       $ amfetchdump SetA vanya

       A more likely scenario involves restoring a particular dump from a
       particular date. We'll pipe this one to GNU-tar as well, to
       automatically extract the dump.
       $ amfetchdump -p SetA vanya /home 20051020 | gtar -xvpf -

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