NAME

       amfetchdump - extract backup images from multiple Amanda tapes.

SYNOPSIS

       amfetchdump [-phcClawns] [-d device] [-O directory] [-b blocksize]
                   [--header-fd fd] [--header-file filename]
                   [-o configoption]... config hostname
                   [disk [ date [ level [ hostname [...] ] ] ]]

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.

       It will automatically use the logs created by amdump(8) to locate
       available dumps on tape, in the same way that the find feature of
       amadmin(8) lists available dumps. If these logs are unavailable, it can
       search tape-by-tape to find what it needs, and can generate new logs to
       serve as an emergency tape inventory.

       The hostname, diskname, datestamp, and level dump pattern-matching
       works as in amrestore(8), with the added requirement that at minimum a
       hostname must be specified when not in inventory mode.

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

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

       hostname.diskname.datestamp.dumplevel

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.

       -l
           Leave dumps in the compressed/uncompressed state in which they were
           found on tape. By default, amfetchdump will automatically
           uncompress when restoring.

       -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.
