tar of file 5GB

[Jairo Campana]

consult:
I did backup (file of 5GB.) with tar1.13.25 that its permit files > 2gb

my questions is:
for restore I must use the tar of default hpux11.0 (that it does not allow backup >2gb)or have use the tar1.13.25 .

[Steven E. Protter]

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 did not understand my question

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.

[A. Clay Stephenson]

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.

[Jairo Campana]

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