     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.



     −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.











                             ‐2‐


     −−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









                             ‐3‐


     −−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.











                             ‐4‐


     −−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).



     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 −



     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.
