Restore a entire directory using tar command

member_unix — Tue, 30 Aug 2011 18:30:16 GMT

Hi All,

Can anyone help me to provide the syntax to restore a directory from tape archive? I am able to restore entire tape and didn't find a correct command to restore a directory. below is the option I already tried. The directory I am trying to restore from tape is alreay created with the same name.

cd /

tar xvphf /dev/rmt/1m <directory name to restore>

tar xvphf /dev/rmt /1m "directory name to restore"

Please help

It might be easier for us non-psychics to help if you showed us (a
relevant part of) a listing of what's on the tape, and revealed what,
exactly, you want to extract from the tape.

tar tfv [...]

> [...] <directory name to restore>
> [...] "directory name to restore"

Hiding potentially important details may not be the best way to get
accurate answers.

Also normally interesting:

uname -a

Operating System.

HP-UX B.10.20

Here is what I get

tar -vxt /dev/rmt/1m

rwxrwx--- 0/101 53066 May 8 00:54 1999 ./symix27/symix/dc/menu-r.r

rwxrwx--- 0/101 81766 May 8 00:54 1999 ./symix27/symix/dc/mir.r

rwxrwx--- 0/101 52291 May 8 00:54 1999 ./symix27/symix/dc/mmenu-r.r

.....

so...on

there is a directory in the system... by the name.

/dev/vg01/symix 3053521 9 2748159 0% /symix27

and I want to restore entire contents of /symix27 from tape archive to sytem directory name symix27.

please help to set the command to restore a directory using tar

Thanks,

   A name which you specify must match the name in the archive. If the
names in the archive are "./symix27/[...]", then you should probably
specify the thing to extract as "./symix27". You should be able to test
this:

      tar -tvf /dev/rmt/1m ./symix27

If that shows you the right files, then, assuming that all those other
options are what you want, I'd try:

      tar xvphf /dev/rmt /1m ./symix27

   Because the names in the archive are relative ("./", which is
normally a good thing), you do need to do that "cd /", as you showed
before, if you want "./symix27" to go into "/symix27".

HP's tar doesn't take a file with -t. But pax does: (Perhaps GNU tar too?)

pax -tvf /dev/rmt/1m ./symix27

   Hmmm. Trust no one, I always say. But, ooh. That's pretty lame.
Even the (pretty lame) VMSTAR on VMS does that. My brain is probably
tuned for Zip+UnZip these days, and, of course, "unzip -t" does it, too.
(It's not a good excuse, but it's the best I can do.)

   GNU "tar" does, too. (Of course.)

HP should get with the program and look at the wealth of features GNU tools bring :-)

Personally, I have grown quite fond of 'pax'. In an HP-UX environment, in my opinion, it is a superior replacement to 'tar'.

For those keeping score, AIX /usr/bin/tar, Solaris /usr/sbin/tar, and
Tru64 /sbin/tar also do it. (Perhaps my brain is not quite so weak as I
had feared.)

Yes, and score one more for Apple Max OS X.

Just another (old) GNU "tar":

$ uname -a
Darwin appleq2 9.8.0 Darwin Kernel Version 9.8.0: Wed Jul 15 16:57:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_PPC Power Macintosh

$ tar --version
tar (GNU tar) 1.15.1

(An OS version newer than 10.5.8 may include a newer "tar", of course,
but I tend to live in the past with my old junk collection.)

Well, for the sake of interest, it looks like this:

$ uname -a
Darwin JRFs-iMac.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386

$ tar --version
bsdtar 2.6.2 - libarchive 2.6.2

...so here's another variant.

It has to be, since pax is the "replacement" for fbackup/frecover. ;-)

Indeed, that's the hope :-) I have not played with the graph ability of 'pax' either.
