In one particular disaster scenario, you don't have a Linux machine with tbackup and trestore at your disposal, but need to get files from your backups anyway.
The following text describes how to unpack a floppy backup set if you don't have tbackup.
PARTAA.001
, PARTAB.002
, ...
from the backup disks.cat
them all together in one large file, i.e.
cat `ls part* | sort` >archive
export dea_unpackmethod=...
line in a
DESCR2K
file on
one of the disks to find out if the archive is a tar
or an afio
archive.
tar
, use tar
to unpack it.afio
, unpack it with
afio
or cpio
.
(Afio produces cpio-format archives.)If you don't have access to a unix machine you may have some luck with
tar
, afio
or cpio
ports to other operating systems
(MS-DOS, VMS, OS/2, amigaOS, ....), provided the ported versions have
a sensible way of dealing with filename limitations.
If you do not have tbackup installed, you can use the lower-level
backup tool tar
or afio
, depending on what pack method you
used when creating the archive to read the tape directly. If you used
GNU ecc to add error correcting codes to tape, you need to read the
tape with ecc and pipe the result to the archiver.
If you don't have access to a unix machine you may have some luck with
tar
, afio
or cpio
ports to other operating systems
(MS-DOS, VMS, OS/2, amigaOS, ....), provided the ported versions have
a sensible way of dealing with filename limitations. Afio produces
cpio-format archives, so you can use a cpio port to unpack an archive
created by afio on linux. Compressed files in the archive will not be
automatically decompressed though.
