Tar with large files

[David_367]

I'd like to use tar in HPUX 11.00 to migrate some database files of size larger than 2GB.
Is this possible?
I read the man doc. It says tar doesn't suport files larger than 2 GB.

Thanks in advance.

Hi,
You install gnutar .With this u can backup the files which are bigger that 2GB.
Download from the following site.

Hi,
yes, hpux tar does not support filez over 2G, and so does gzip.


IF you must move this files is better to use fbackup/frecover, dd, or a commercial product.

David:

Try the gnu tar:

I will also try fbackup and frecover.

As mentioned, industry-standard tar does not handle files over 2Gb. This is also true for cpio, pax and other legacy Unix tools. Large files usually contain important data and should be handled with appropriate tools for reliable data transfers. To transfer between two HP-UX systems, use fbackup. It is much faster (use a config file) and much more reliable.

And although there is a patch for tar to handle files up to 8Gb, the resultant tar tape is incompatible with other HP-UX systems without the patch and also incompatible with other Unix systems. GNU tar (the right version) will handle large files but the same version of GNU tar must reside on the target system too.

If this sounds like a call to evaluate backup methods, it certainly is. Dozens to hundreds of gigabytes of data demands a careful decision about the backup solution. Gigabytes of data is too expensive to recover from a cheap backup program that can't handle tape problems.

David -
I documented the attached, for fbackup of large files, last time I needed to.

Best of luck.
