I tarred a directory to a different location. I then deleted the original directory.
Now I need to restore the directory, and I am unable to do so (The contents do not get restored). However, when I type tar -tvf <tarfile), the list of contents are displayed :
What actually goes wrong when you try to extract the tarball ? You say the contents do not get restored - but what actually does happen ? Is there an error, or anything else out of the ordinary ? You'll have to provide a bit more info regarding what is actually going wrong here before anyone can assist further.
Just guessing - tar usually removes leading \ when archiving, unless told otherwise. Is it possible that your restore ends up just below the cwd?
Did you mean leading
Code:
/
?
About the output from the tarring :
I just ran the command :
Code:
# cd <tar file directory>
# tar -xvf lhs20170405.tar /home/lhs
Then there was nothing.It just ended with a prompt without any message/error.
And when I checked the /home/lhs the folder was still not there.
Even performing a bdf /home still showed same usage as before the tarring was done. (6%).
Just guessing - tar usually removes leading \ when archiving, unless told otherwise. Is it possible that your restore ends up just below the cwd?
That is only the case for GNU tar AFAIK... Regular tar's will happily oblige and store the leading slash. That is why one usually creates a tar with a relative path from the / directory..

@OP:
Try using a chrooted environment...
Or try removing the leading slash by using POSIX compliant pax, which should also be available on your system :
Code:
pax -r -s '|^/||' < tarfile
First cd to the directory where you want the tree to be created, like you would do with tar ..

I think I can sort of replicate this on Solaris, using the SunOS native tar rather than GNU tar (which handles this fine).
As counter-intuitive as it might seem, try syntax like this:
Code:
tar -xvf lhs20170405.tar home/lhs
So actually leaving off the initial / basically. It will then extract it underneath wherever you are, and you can move it in to place.
Generally leading /'s in tar archives are not a good idea. GNU tar automatically strips them, as RudiC says; it seems SunOS tar (and I'd also guess HP-UX tar as well, by logical extension) doesn't, and will actually create an archive with them in it.
Different OS's implement tar slightly differently.
With the information provided I'm still guessing but......
Just see what happens if you list without entering the minus.....
Code:
# tar tvf lhs20170405.tar
and if that lists okay then try
Code:
# tar xvf lhs20170405.tar
again without the minus.
Anyway you should be able to tell if it is actually extracting because (a) it will be slower than just listing, and (2) the disk activity light(s) will be reallt flashing whilst it's writing the files down. If you do see a difference in the two operations then you need to go find where tar has extracted the files to.

And regarding your post#4, if you use the 'v' (verbose) option on the extraction command line, all files will be listed as they are extracted. Therefore, I would say, no output indicates no extraction occurring.
This will be covered elsewhere im sure but i just cant seem to find my exact issue.

I created a relative backup of my home directory using tar into a file named backup.tar.
No problem there.

But, when I tried restoring backup.tar into a... (2 Replies)
I backed up a unix database using
"tar -cvf /dev/rmt1 -N 800 /*"
Normally I would restore this using
"tar -xvf /dev/rmt1 -N 800"
This is reporting an error about
"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)
