HP has a tar upgrade that allows files up to 8 GB.

Make sure the target filesystem has largefiles enabled before you restore.

This is one of the problems with using something like tar for large files. As far as I know you MUST use an equivalent version of tar to do the restore since the native version of tar does not handle files larger than 2GB.

You could try using the default version of tar, but I have a feeling it will not work. You should install the tar 1.13.25 that you used on your other machine.

An even better option would have been to use fbackup to back up the file. fbackup handles large files and is also quite portable between HP-UX platforms and is native to HP-UX so there is nothing else to install.

You'll have to use the 1.13.25 (or latest) version of tar.

Use 'cksum' on the original and copied 5gb file to verify integrity of data.

cksum original_file
cksum copied_file

And I believe you'll need 13.25 on the destination machine. So just 'ftp' or 'rcp' it over. Should be in /usr/local/sbin but 'which tar'.

Also, here's the download site:

not understand my question
jairo.bak 5GB.
have a backup with tar1.13.25(supoort >2gb) ok.
in /usr/local/bin/tar -cvf /dev/rmt/0m jairo.BAK
so,for restore use tar1.13.25:
/usr/local/bin/tar -xvf /dev/rmt/0m

or I cant use the tar default of HPUx(/usr/bin/tar)without problems

As my understanding, you move the backup to another machine without tar 1.13.25. I believe you should install the tar 1.13.25 to untar the backup.

Once you use Gnu tar the only safe method is to use Gnu tar to restore. The patched version of HP's tar (that allows up to 8GB files) might work but Gnu tar WILL work.

yes,yeeeessss, twang: the questions is
I can or I cannot .
I must install in the other server tar1.13.25 for restore

Re: tar of file 5GB

Patrick Wallek — Thu, 26 Jun 2003 16:01:55 GMT

Yes, you must install Gnu Tar 1.13.25 on the server you are restoring to.

Re: tar of file 5GB

Pete Randall — Thu, 26 Jun 2003 16:02:31 GMT

That's what I said, I think! You'll have to use the 1.13.25 version of tar to restore the file on the other server. If it's not already installed, you will have to install it.

Hello!

Yes you must use the version that you made a tar for open it so you need to work with tar1.13.25 that you used!

Also if you will have a newest version it also should work because of the suport backware.

!!! IMPORTANT: THESE EXAMPLES ONLY WORK IN KORN SHELL (KSH) !!!

Use the UNIX pipe and split commands:

Export command:

echo|exp file=>(split -b 1024m - expdmp-) userid=scott/tiger tables=X

Note: You can put any "exp" parameters. This is working only in ksh

Import command:

echo|imp file=<(cat expdmp-*) userid=scott/tiger tables=X

Splitting and compressing at the same time:

Export command:

echo|exp file=>(compress|split -b 1024m - expdmp-) userid=scott/tiger tables=X

Import command:

echo|imp file=<(cat expdmp-*|zcat) userid=scott/tiger tables=X
